XJ Expedition Basics

[brockmub]

OK, guys and gals, I'd like a little guidance on this one. I've been a member of a lot of different forums and have lurked here for a while, but just finally decided to join up. The reason is that I'm surprising my wife in June with a little road trip from Sioux Falls, SD to Imogene Pass to Puerto Penasco for a wedding anniversary/mission trip. Essentially, she has no idea where we are going and want to surprise her with a mini-adventure to whet her appetite for more.

Question is... What are the top things I should consider when preparing my 2001 Cherokee for the two week trip on Interstates, Mountain Passes, and Mexican Desert?

My wife is going to love a little adventure but would not exactly be thrilled at being stranded some where. Can you help a guy out? I love cshontz's build but am I naive to think I can do it with my stock gray XJ?

Welcome aboard!

To answer your question: Preventative Maintenance!!!!! All the usual stuff - fluids, grease points, cooling system, belts/hoses, tire balance, brakes, wheel bearings, stuff like that. If you break something in an extreme situation or in an emergency, that's one thing. But to break something that is really a PM issue...that's no fun at all. If it is worn out, or nearly worn out, just replace it - you're going to have to do so sooner or later, and it is better to pick your time for addressing this stuff, right? So often folks focus all their energy on flashy accessories and "upgrades", when in reality all they really need is a reliable, well-maintained vehicle to get out and enjoy an adventure.

From there, organization. If you're going to be living and camping out of your vehicle (or just living and staying in hotels, frankly) then everything should have its place, should be boxed up and strapped down, and the vehicle should not be overcrowded with goods. Items should be strapped down for safety and to keep the annoying bouncing and rattling of cargo to a minimum. Where possible, take items that will serve more than one purpose, saving space, weight, and reducing clutter.

Good maps, a few planned destinations and a sense of the other cool or curious stuff along the route. Bring along your preferred soundtrack for the adventure (music, book-on-cd, whatever). Look at the route and see what other people have liked about the places you're going to pass through.

Recovery gear, tools, spare parts as appropriate for the destination, the route, and the vehicle. Find the right balance here, and pack accordingly.

I'm sure other folks will chime in with other ideas, but in my experience exploring by car on pavement and off, these are the things that I've found to be important.

Extra gas... you can get pretty far between gas stops without trying ;) and on you never know if the little town's station will be open or even have gas.

For Imogene and other "off the beaten path" trails you should be able to air up and down by yourself.

Maybe keep a list of the guys here that volunteer help and support if you are in their neck of the woods and need assistance.

[brockmub]

So far awesome advice! I'm sort of heading down that route already so I don't feel like such a noob. Probably should have stated what I already started doing to prepare for the trip.

A couple of summers ago, my brother and I took an off-road training from Mark Filonowich at the Iron Range Off Road Park in Virginia MN. Had a blast, got stuck, no major carnage other than a broken plastic center cap, and learned what the Jeep was capable of. Can't recommend him enough! For the course, we mounted recovery hooks on the front, then used the receiver hitch at the rear recovery point. (you might be able to see the hooks if you look closely enough)

http://lh5.ggpht.com/_lBceBoAHK6c/S9w5FKawDCI/AAAAAAAAAbM/Qr9aAStTZjo/s800/IMG_2215.JPG

There is also a small recovery bag that stays in the Jeep at all times, super helpful in winter, and you never know when you're going to need a hammer.

http://lh6.ggpht.com/_lBceBoAHK6c/S9w5FxvSsPI/AAAAAAAAAbU/D4DIaAirv58/s800/IMG_2227.JPG

In the bag, there is always my 30' tow, large and small clevis, receiver pin, gloves, tape measure, crescent wrench, screwdrivers, hammer, pliers, and tape. Really should throw a roll of duct tape in there too. Not a big bag but what else should I drop in there? I keep my Leatherman in the glove box with my mini LED Mag.

Went through both differentials last fall, checked the optima battery, and all other normal maintenance points this Spring. However, the check engine light came on last week after a particularly rough initial start and idle. The Jeep seemed fine after that but the engine light was still on. So I ordered the....

http://lh3.ggpht.com/_lBceBoAHK6c/S9w5FZJ9TGI/AAAAAAAAAbQ/X5jxuSB_XWY/s800/IMG_2213.JPG

ScanGaugeII. The Scan Gauge cleared the trouble code and showed me that there was a misfire on Cyl 3. Just going to keep an eye on that during the month before we leave.

Maintenance left to do...
1. Keep eye on Cyl 3.
2. Replace cracked front windshield
3. Fuel injector cleaning (might take care of Cyl 3)
4. Oil change
5. Coolant change

Thanks for the tips, keep them coming! I'm up for the adventure, but like being prepared!

[Root Moose]

There is a TSB for the misfire on #3 (if it is the same thing). Heat from the engine makes the fuel injector at that location too hot. The TSB kit has little insulators to wrap around the injectors to protect from heat. Amazingly it works in spite of the heat soak.

[wikun]

There are a few things that you could add to the list to do and throw in the bag. The engine scanner and code book is something that is always in the vehicle somewhere. This has been helpful on the trail or more particularly at base camp. Others need it and you have it. Second, with the misfire. You are right a great place to start is the fuel injector cleaning. And not just some tank additive. A full cleaning where they remove the injectors and clean them offline is best, but there are other quicker and cheaper alternatives, just ask your local mechanic. I don't remember what year you have so if you have a distributor cap, pop it open and check the points for burns or carbon that could make you miss and throw a code. Next the plugs. Let the engine cool and pull the plugs. Just a once over for peace of mind. And if any are showing wear, just throw a new set in. Other than the PM that you have mentioned, you should be good to roll. If you might get into some more technical stuff, you might want a new/spare yoke, or install a SYE. Some wheel bearing grease and diff oil. Other than you should be just fine. Oh and make sure you HAVE FUN:sombrero::sombrero::sombrero:

I really like the ScanGauge so far... I think I'll keep it Velcro-ed to the steering column but I was thinking that maybe I should print out the trouble codes and keep them in my travel binder on big trips. Maybe if it gets mounted in a more permanent place, I'll get the additional cord.

How necessary are 8 and 9?

[cnskate]

I would bring an extra crank position sensor and the necessary tools to change it. Fuel pump too maybe? Fuel size spare, compressor, tire patch kit. Does your lady like heights? If not, she might not thank you for Imogene Pass:coffeedrink:

[shogun]

How necessary are 8 and 9?

I have had two pumps die on me, the first was intermittant and drivable until replaced. The second left me stranded for a half hour in the desert, luckily it started and we avoided a several hour walkabout. It died a week later on the side of the road, tow away. They cost about $100, and take maybe an hour to change.

The belt is cheap and given that it runs all the ancillaries, could ruin your day. I've never had one break, yet. Cheap insurance.

Actually she's on the flight team at the local hospital, so she might be more ready for this than I am.

Haven't heard about bringing a CPsensor before. I'll throw a fuel pump in, sounds like that's a safe bet. Not sure what a fuel sized spare is?:coffee: But I do have a full spare already and I'll have a little compressor along. Never patched a truck tire before, but it can't be much different than my Tri-bike.:Wow1:

[jacobfreeman]

I am glad that you posted this thread.. I am getting ready for the exact same situation as you haha. Heading out on an 2 or 3 day expo trip! :smiley_drive:
Have fun!

[A7XJ]

Fuel pumps do not like heat. So if you happen to pass through AZ in the summer it might not hurt to have a spare. I replaced my serp belt and carry the old one as a spare. I have a few extra 2001 Jeep XJ factory service manuals, so if you happen to pass through mesa AZ on your way to mexico I'll be glad to give you one. They are an amazing help if you need to know how to replace or dianose anything on your jeep.

[SWbySWesty]

Can we get more info? Are you camping and being self-contained or are you posting up in hotels? The answer to that questions will direct what I'd recommend from my Baja and other trips :)

[Rosco862003]

Some say that he has to remove his shoes with an allen key, Some say his nipples are shaped like the nuremburg ring...All we know is that hes called the stig and hes on Expo Portal wearing a bow tie...Also nice to see that hes modest enough to drive a Cherokee!

[hugh]

Spare rad hoses and a couple of feet of ATF rated hose might also come in useful. Cherokees as a rule are pretty reliable. Having said that, when I go out I like to carry a spare steering link setup. On mine I upgraded to a ZJ steering and keep the old set up as a spare. Experience has taught me the steering linkage on Cherokees is vulnerable to rocks. On that note a spare unit bearing for the front wheels can't hurt, along with the necessary tools to change it out. Also a transmission cooler is nice the AW4 does not like heat.

[XJINTX]

I agree with most of this list. I would (time available) replace the top and bottom radiator hoses and serp belt. Good maintenance if you have not already and it gives you spares. Easier to change at liesure at home rather than on road.

A triple A membership is a wise choice too :)

[brockmub]

I probably would have done most of the things that are being suggested, without posting on this forum. However, no matter who I talk to or where I go, there are always little grains of information gleaned from the conversation. Maybe 2 weeks is a bit ambitious, but the areas that we are going to hit are pretty safe and well known. Jacob... where are you going?


Can we get more info? Are you camping and being self-contained or are you posting up in hotels? The answer to that questions will direct what I'd recommend from my Baja and other trips :) I will probably be posting a trip report as we are travelling and much of it is very open ended. But there are a few points that we HAVE to hit:

1. Denver - new god-daughter born and haven't seen yet
2. Ouray - not exactly interested in rock crawling but growing up on the plains has drawn me to high mountain passes like Imogene.
3. Phoenix - meeting old college friends that are definitely kindred spirits so we can drive to...
4. Puerto Penasco - doing a church mission trip to build a small spec home for a local family
http://www.onemission.us/vision.php

Every where else is up in the air. Coming back from Mexico, we might go north to Utah and east through Wyoming but who knows were we will go. We can probably take highways if we wanted but could also take some dirt. The wife probably won't have the patience for an entire 2 weeks of dirt.

I never know what to use as an avatar, so Stiggy got the nod on this one.

With all of the mention of fuel pumps, I'm going to put on in my ActionPacker. I think it's probably a good idea to do what you suggested and replace my serpentine belt, and keep the old one as a reserve. We should be through Phoenix on June 10th and then again on the 14th. We might take you up on your offer on the extra service manual.


Can we get more info? Are you camping and being self-contained or are you posting up in hotels? The answer to that questions will direct what I'd recommend from my Baja and other trips :) Really thinking about going the B&B route with a few hotels mixed in. There also is a bit of a problem with the mission at Rocky Point so we might be camping there. In case we want to camp more of the trip we are bringing most of our camping gear - 4 man tent, thermarests, and bags. But I would not consider this trip "self contained"

On that note a spare unit bearing for the front wheels can't hurt, along with the necessary tools to change it out. Also a transmission cooler is nice the AW4 does not like heat.

Radiator hose - check. I might have some left from my Blazer project. The transmission cooler has always been an upgrade that I've wanted to do. Again, I might do it on my Blazer and then on the Cherokee.

I need to flush the radiator and swap out fluid so that would be a great time to change the hoses. The AAA membership is already taken care of. Kind of feel like an old blue haired lady when I think of AAA but its saved me once or twice before.

Saftey Seal tire puncture repair kit and a GPS are two things I haven't seen mentioned yet.....

Tire Repair Kit ... check. As for navigation it's maps and just in case, my (don't make fun of me) Moto Droid.

http://lh4.ggpht.com/_lBceBoAHK6c/S92mUVwJzYI/AAAAAAAAAbc/UEUQ3Thz-UA/s800/motorola-droid-2.jpg

Love this phone. Will probably use it just to keep track of where we've been with the GPS My Tracks. I know it's not a Garmin or a SPOT but I think it will do just fine. It's been great for navigating cities, picked up rural South Dakota just fine, and keeps me in touch with the outside world (if I want to). Bring on the GPS vs. DROID hate... but I'd like to rely on maps more. I trust paper for some reason.

[XXXpedition]

honestly, i don't know what to tell you...
i put 250k very hard miles on my 94 XJ and the only things i ever swapped was water pump, power steering pump and alternator (except aftermarket stuff).
the engine always ran strong. i'd bring a spare belt and tools if you don't do any serious 4x4ing you should be fine...
i always had slight problems with overheating until i dropped in a radiator from alumrad.com - that did the trick.

i think the 4.0l is an awesome engine and the truck should run for a long time...
have fun on the rip!
sven

[kc0tma]

One super important thing to remember too is a nice bottle of wine and some fine chocolates. I know from personal experience that going on a jeep drive for a date can some times turn into more of a guys trip where you are dragging the wife along when it should be the other way around.

Maybe it's just me, but every time someone mentions something, I notice something about my Jeep that I hadn't before. The steering fluid level dropped a few weeks ago so I topped it off. Now that I just drove it, the level is fine but the wheel doesn't seem very smooth on turns. Probably just paranoid, but does that sound like it's going out?

[cnskate]

I posted a thread on NAXJA awhile back asking people what sort of breakdowns had left them stranded. CPS came up several times. You might look up the thread.

Depends on how many miles on your truck, I suppose. My starter and water pump crapped out at about a 100k miles. I bought new, not rebuilt, parts before my last month long desert trip.

Sounds like you are not going to far off the tarmac and the AAA lifeline, so I wouldn't worry too much.

[SWbySWesty]

Since most of your trip is in the US, I agree with XXXpedition. You don't really need much. If you're staying at B&Bs and mostly paved roads, then a full size spare tire, tire puncture kit, water/food in case, engine fluids (premixed rad fluid, engine oil) and other little doodads I'd call it set.

Unless you're going somewhere REMOTE, then you'll usually be near enough a town or something to call AAA if you have a break down in the US.

In Mexico, that's what you have the toolbox, fluids, and tire kit for, but as has been mentioned, if you maintain the rig (bushings, seals, gaskets etc) then you should always be good to go!

ENJOY!

Man, why have I never heard about the Crank Position Sensor issue until now? Have I been living under a rock? I've heard about exhaust heads cracking, o2 sensors going out, rough idle with AC, and blown head gaskets... but no one has ever told me to watch out of the CPS.

Hopefully will get the Jeep in the shop this week to finish up the other loose ends for the trip. Roughly one month left till we take off. Once the Jeeper is buttoned up then I'll need to start focusing on parts of the trip like tips on Imogene, Monument, and other parts.

[troy]

I agree with the responses posted above, but not sure I agree with carrying a spare feul pump. '97-01 cherokees have the pump in the tank and it is fairly expensive ($2-300) and is also delicate so you'd have to keep it in the box which is good sized (from memory - 8"x8"x15").

While I agree spare parts are good, a feul pump on these models is not an easy roadside fix. Drop the tank, hope the pump went out when it was near empty. Mine had 3/4 of a tank and it nearly killed me to get it down. To me, this is when you actually use AAA or some other roadside assistance to get you off the road and back to a place where you can do the work, or have someone do it. Through my insurance company I pay about $8 a year for roadside assistance.

A better bet if you are really paranoid about a fuel pump going bad is some rubber hose, hose clamps, small electric fuel pump and some wire.

'97-01 fuel pumps do go bad, but is usually the diaphram that maintains pressure in the line. This causes hard starts, but the pump is usually fine. They start giving these symptons for a long time before it becomes an all or nothing issue. Temporary fix is to cycle the key on and off for 2-3 times, this will put pressure in the line and allow a faster start. Then you can repair it at your liesure when you get home.

Another item that is an XJ specific problem in the Nuetral Saftey Switch acting up and not allowing the Jeep to start. There are some instructions on NAXJA on how to bypass it (print and put in glovebox). Simply crossing a couple wires right by the back of the valve cover. Not the safest thing, since it will allow you to start in any gear, but all you'd need is some electrical tape and wire cutter. It'll get you home in a pinch.

You may also want to throw a couple of extra relays in your glove box. The rectangular fuse box under the hood has a couple relays that are known to go bad on occasion. I know one is for the starter (most important), and there are a couple more. They may be the same relay for all, and they are like $10-13.

I've got 233K on my '98 XJ and I've drive it anywhere. Only major things I've needed to do was Fuel pump and NSS. Basic maintenance and you should be fine. Other items have just been inconvenience items like A/C, power windows, etc.

Sounds like a good time. Have fun.

Troy Thanks!

You made me feel a lot better and worse at the same time:Wow1: The Jeep has given me 70K miles of problem free driving and I have always maintained and garaged it to the best of my ability. I have the utmost confidence in it getting us there and back. So a belt, relays, and a few other small parts might be all that I take because I don't have a lot of faith in my field repair skills. My repair experience is mostly with my old Blazer and some old motorcycles that I once had. They were projects that I could work on for a couple of hours, then leave if I ran into problems or needed parts. In this case, it's fix it or hoof it.

Maybe as our first long expo we shouldn't get too crazy and as a result we shouldn't need too many parts. This forum has been awesome so far... keep it coming!

I cannot speak to the later model pumps, my pump is smaller than a coke can (about the size of a fist) and cost $105. While I havent done it, I think it can be changed in-situ due the the tank mount plate being on an angle, which should allow you to reach up and remove the sender/pump unit. Agreed, you dont want to drop a full tank on the trail/street. I've since upgraded my tank and installed an access plate in the rear floor, about a 30 min job now. Yes, I suppose you could kluge a secondary pump. Yes, they do give warning, at least mine did, if you recognize what it is. But it may be a couple years or a couple days out. Not everyone is going to replace the pump the first time the engine hiccups.

NSS is a thought, I 've never had the problem but a good backup plan.

My general consideration isnt completely "what can I do on the side of the road", but also "what can this garage in the middle of nowhere fix on a sunday afternoon". I'd rather have a few parts to hand the guy rather than wait for the UPS/DHL truck. Its easy to go overboard, but a few inexpensive (<$100), vehicle specific parts can easily be carried.

Troy Thanks!

The point of my post was that you are traveling the bulk of the trip in the U.S. and just dipping into Mexico, your Jeep is well maintained and you're plannig for basic repairs. Parts for these trucks are cheap and easy to locate on your planned trip.

My first expo related trip was 10K of driving through the western U.S. I had an '88 wrangler and just my college girlfriend with. It blew a head gasket in Rawlings, WY. The dealer knew I was in a pickle and wanted $2,500 to do it immediately. I parked the jeep and rented cheap car (40 mpgs) and continued the trip. Once I was back in Rawlings, I thought of renting a U-haul with a tow dolly, but ended up limping the truck back while my Dad headed my direction with a car trailer.

The net cost of the trip was about the same (40 mpg vs. 15 mpg) and we had a blast. You really can expo travel in anything. I had the Geo metro on 3 wheels in several occasions in Moab.

BTW - I repaired the head gasket myself and drove it for another six months until I let the girlfriend borrow it. She overheated it and kept driving until it stopped. Installed new engine and got rid of the girlfriend shortly thereafter.

Traveling across Africa or a remote location is one thing. Put some cash in your pocket, fill up the tank and worry more about opportunities to drink the wine you're bringing.

That is a great approach for someone like me to have. Especially if I plan on keeping my Cherokee for while, some thing like the fuel pump will probably go out. If I have it sitting in the garage after the trip, I can take care of it when I have the time or need. Got stranded in Iowa on a Sunday afternoon when my Dodge Daytona broke down. Thank goodness Chrysler put those crappy 2.2 motors in everything because the shop salvaged parts from a minivan behind the garage.

Now we are getting into the spirit of things here. I've been craving fish tacos and margaritas for about a month now.:sombrero: I liked your story Troy. My brother and I went on some trails around Pikes Peak last year. We were about 6 miles in on one semi-rough trail and were met by a Honda Insight! I'm not kidding, the guy just waved, and continued on. You can expo in anything.

I had the NSS go on my '98, it was a PITA because it would start sometimes, and not start other times.
Most of my broken parts are from abuse, driving through silty/muddy water 100's of times etc.

The NSS is pretty small, and usually easy to change out. Mine was frozen in place due to SEVERE rust, so I had to have a shop change it for me. Everyone else on NAXJA seems to have been able to change it themselves.
That might be a part you buy, seal up in a couple of zip lock bags and just keep around for a while until your original fails. But that might not be for another 100,000 miles...

I've had 3 alternators go, and front wheel bearings (twice now) as well, steering pump, still on original fuel pump though!

Again, most of replacement parts were damaged from abuse due to offroading through very wet and muddy conditions. If your XJ hasn't seen a lot of trail abuse, you will likely not have to change out any of these for quite a while.

Other than that, I hope you have a great trip!

At 103K, my Cherokee isn't a spring chicken anymore but it's also been really well maintained. Even though a lot of vehicles have problems start showing up at that point, we probably will be safe. I'll try and compile some of the parts that everyone has suggested and stash them in the under-seat compartment in the back. Which is where my rain poncho and extra-extra set of gloves are and I had forgotten about. Should be able to stash the serp belt and fuel pump under there along with maybe some relays or sensors.

Another question... how often do you guys replace your 02 sensors on your 4.0? A jpmagazine.com article suggested every 3-4 oil changes:Mechanic: Can't say that I've ever replaced one on any car that I've owned.

[brockmub]

Here's the article I was talking about... they mentioned a lot of the sensors and connectors that everyone else did. Just goes to show you how good of advice you were all giving out. However, I think that some of the problems that were mentioned pertain to older models of the XJ than my last of the run 01'.

[troy]

I was of the understanding that a bad O2 sensor will trigger a check engine light. Maybe there is a range they operate in and as they get older, they make the engine run less efficient? If your MPGs are trending the same, I'd leave it alone. They are $50-80 each, so fuel savings would have to be somewhat significant to warrant the cost.

This is also not a "leave you stranded" item. It may be more realistic to replace them at mileage intervals, ex. 30K or 50K. If you change oil every 3K, at the 3rd oil change that is only 9K miles. Sometimes I don't even rotate my tires that frequently. I personally will run them until a check engine light or bad MPGs.

Just my opinion, so take it for what it's worth.

[Root Moose]

Every 3 or 4 oil changes?

LMFAO!

Does Jp have stock in the O2 sensory industry?

[brockmub]

That's what I thought too, because I had to read it three times.

Just scheduled an appointment to have the fuel injectors cleaned and power steering checked out. Any opinions on having the fuel system cleaned with the MotorVac?

[The Adam Blaster]

Another question... how often do you guys replace your 02 sensors on your 4.0? A jpmagazine.com article suggested every 3-4 oil changes:Mechanic: Can't say that I've ever replaced one on any car that I've owned.

That's plain nuts...
If I started changing O2 sensors every 4 oil changes AFTER I had hit 100,000 km (I'm at 200,000 km now) I would have had to replace the sensors 5 times now. (Oil change every 5000 km.)
Up here (Canada) they cost about 100 bucks each, there are 2 of them on the Cherokee. $200.00 + labour (2 hours probably) X 5 changes, that's $1000.00 in parts alone, probably double that including labour if you have a shop do it.
They aren't that hard though, you could change them yourself.
But I don't see any need to do that.

Ironically my XJ is in the shop right now getting both sensors changed. But, I work for a chain of tire/mechanical stores so I get parts at cost and 50% off the labour rate. (So getting the shop to change them for me is about the same cost as anyone else buying the parts at full retail and doing the work themselves.)
This is the first time I've had to change the sensors since I've owned the Jeep, and I could easily tell that it was running rich by the exhaust smell. But, I don't have a scan tool and that's why it went to the shop and let them hook up the scanner.
On a Cherokee I think changing the O2 sensors every 30,000 - 40,000 miles would be prudent, and at that point they probabaly wouldn't "need" to be changed.
If you're hard core into preventative maintenance, then that schedule would make more sense than EVERY 3-4 oil changes...

[The Adam Blaster]

I posted my response without reading everyone else's.
That JP suggestion really freaked me out! lol

I agree that the O2 sensor will trigger the check engine light and give you poor gas mileage because that's exactly what it did to me, along with the unburnt/rich fuel smell.
Before I put my larger lift and 33x12.5 tires on, I had 31's and was getting about 500 km to a tank.
After the lift I was getting MAYBE half that. I never went to E though because I was worried about getting stranded on my drive home! :Wow1:

I knew that the lift wouldn't make that much difference in fuel usage, and of course the smell gave it away also. I think that the check engine light was on before I did the lift, but that was a couple years ago when I parked it, so I can't remember for sure...

The other big thing with mine was that at 4000-5000 RPM it would blow black smoke from the tailpipe like a diesel accelerating hard, yes it was literally a huge black cloud.
So, there's 4 key indicators that can tell you your O2 sensors are gone, and you'll still be able to drive the Jeep, you'll just use a lot more fuel. ;)

I'm wondering if any of my spark plugs are fouled now???
I guess I'll see how it runs after the sensors are changed...

[HenryKrinkle]

At the above guy: hope your cat is ok after that situation. That kind of fouling will plug them up quick.

[TOTJ]

I agree with evrything above.
I would not go anywhere w/ out a extra CPS. but I would also add
a idler pully. I have seen these just fail and your dead in the water.
Its less then 20 bucks and it is small. I even carry one in the Rubicon.

[sjk99]

Going to Mexico. If you are bringing a firearm for the rest of the trip check it and any ammunition or any other firearm related item (cleaning supplies, spent brass, magazines, targets, anything) at one of the stores that offers the service in either Ajo, Why or Lukeville. If the Federalies catch you with anything gun related they do not fool around and you'll most likely do some time in a Mexican jail. Really.

I will probably leave my gun at home. Thanks for the tip though... that's something that people will often overlook in their preparation. We're going to be on this trip to see the wildlife, not hunt and kill it. :elkgrin:

Ok... Crank Position Sensor is on the list. I'll pick one up and stash it under the back seat. I think these three are the last parts that I'll add to the trip.

1. Fuel Pump
2. Crank PS
3. Idler Pulley

[The Adam Blaster]

I'm hoping I was able to avoid damaging the cat, I only ran about 1.5 tanks of fuel through the engine before getting the O2 sensors changed.
If I start a thread on here about having to get a new cat then you'll know! lol

And plus the OP said this Mexico trip has half wedding anniversary and half mission trip. In a mission trip you are doing the work of god and trusting him if I'm correct (am atheist), so isn't that contradictory to think you will need a gun for your own protection?

[ExpoMike]

O2 sensors typically fall under the emissions related items, which I believe under Federal law must last for 75,000 miles (CA I think it's 100,000).

If you are changing O2 sensors sooner than 75,000 miles you are either throwing away money or you have another serious problem you need to fix. In my 25+ years of working on cars and owning 38 vehicles, I have yet to replace an O2 sensor. YMMV

That said, having 104,000 miles on our XJ, it might be something to think about doing but at the same time, the most recent smog check (Feb) showed that is is almost putting out cleaner air than what is coming in. LOL

I still wouldn't get a OEM fuel pump, do the in line get you by method as dropping that fuel tank is going to bring the suck in the hills - I know someone posted that it is on the front of the tank but that is only true on older XJ's your 01 it is only accessible by dropping the fuel tank.

This forum cracks me up! Such a wide range of beliefs, opinions, and experiences and thats ultimately what most will find on their expeditions. I trust that God will take care of us and I also trust that God has given me enough intelligence to prepare for such a trip by joining an online forum.

Ha Ha!

[mudbutt]

Just scheduled an appointment to have the fuel injectors cleaned ....

Find out how much that costs first....

I was having trouble with my F350 and they benched the injectors.... Cost twice as much as new ones if I did the work myself..

[brockmub]

Got the MotorVac done yesterday and spent the day driving around doing errands and testing it out. It really feels like it makes a difference on starting, but that might be just my wishful thinking or bias. There is a definite difference on the idle. I believe it's worth the money.

It used to be at stop lights, I could hear the motor rattling all the way back through the muffler. That sound and roughness is gone. It might be snake-oil but I can't deny that there is a difference on idling. As for gas mileage or HP increases, I can't say other than it "feels" like its better.

Flushed the brakes and that made a nice difference. Brakes are more solid and stopping distance has decreased... all from a little flush. Coolant is flushed and fresh too.

Had the guys at the shop checkout the steering pump and they noticed the little bit of shakiness I was experiencing but couldn't find an answer for it. If it gets worse, I'll consider replacing the pump, but that can be one for another day.

Departure in less than a MONTH!!! My wife is starting to figure things out about the road trip, we'll see if I can keep it a surprise long enough.

Absolutely agree, O2 sensor (OEM or higher quality) should last 75,000 mile or more. Besides that if 1 fails on the trail just disconnect the other 1 and it runs in a default mode enabling you to complete the trail. Then stop by the auto-parts store for a replacement after you get back home.

Good thread and fun read. Last year I attempted (the operative word) my seemingly routine drive back to the east coast from Colorado. My pesky check engine light came on the morning I headed out. I didn’t think too much about it until about mid-Missouri when the Jeep sorta just turned off while clipping down the I-70. Miraculously, I coasted up the off-ramp and within spitting distance of the Missouri Jeep dealership. They were closing in 30 minutes so I quickly Googled some options on my iPhone. I presented the internet options / opinions to the Jeep folks & they told me to have the auto parts store order a CPS for starters. They said I could wrench on my Jeep in their parking lot all weekend long, but the beer light was on and they were closing shop.

The next morning the auto parts store tried to sell me the wrong CPS. Luckily I had pulled the CPS during my “free time” and could show them that it was obviously the wrong part. In the afternoon they got in the right part, but after installing it the Jeep would still crank & not fire. Since I had another day of “free time” on my hands I decided to remove the gas tank skid that I installed ten years prior, drop the ½-full tank, pull the fuel filter and stare at it. I won’t go into the myriad of improper and unsafe use of tools, straps & jacks to get it all off. I looked over the fuel filter, not really sure what I was looking for. Heck it took me 30 minutes to figure out how to get the dang filter out of the tank in the first place.

Three hours, busted knuckles and smoked forearms later the tank and skid plate were back in/on. That night I got cleaned up, found a local karaoke joint and got hammered. I was running out of options because I had to be in North Carolina on Monday, so my best option was to catch a ride back to Kansas City and fly the rest of the way. But before I left, I wrote a detailed letter to the dealership with a business manager of a business which was located nearby. Below are the pertinent parts of the letter:


… I was travelling eastbound on Interstate 70 when my Jeep Cherokee suddenly died. I thought the cruise control kicked off, so I applied more throttle, then the idiot lights came on, and all power stopped. I coasted off the Interstate onto the frontage road where some of your staff helped tow it to its present location. At first, I thought it got hot on just turned off for whatever reason. I let the Cherokee cool for an hour before and tried a few times to get it going.

Presently, the Cherokee will turn-over but not fire. If I bump the ignition a few times, it will sputter once or twice and die. Spraying starting fluid into the throttle body does not do any good either. That is when I was officially stumped; I figured it would at least fire a few times. Since the CPS I had ordered from O-Riley Auto Parts wouldn’t be here until 11am on May 31st, I figured I would at least go through some of the troubleshooting steps since I had plenty of time on my hands.

I performed the following troubleshooting/maintenance on the Cherokee on May 29th & 30st:
• Pulled the codes using the on-off technique with the ignition:

Codes:
12 Start
25 automatic idle / speed motor circuits
11 ignition reference signal
55 Finish

• Ensured the engine ground block was clean
• Checked all fuses & relays, just ‘cuz
• Replaced the Crank Position Sensor
• Ensured the fuel pump was turning on at ignition
• Double-checked the fuel pump relay
• Pulled the to-the-engine fuel line to make sure it was pumping fuel
• Checked the fuel pressure at the fuel rail: 35psi (ruining an air pressure gauge)
• Pulled the fuel tank off, to ensure all of the connections and fuel lines were in good order (I was once told that there is a fuel line/hose inside the gas tank, which if broken, would cause the system to lose pressure or vacuum. I did not fish around in the fuel since my hands were dirty, but I did not observe a fuel line or hose inside the tank.)
• Pulled the distributor to look at it. Didn’t see significant burn anywhere.

I know my air cleaner is dirty, but I did not think that it would matter too much or kill the Cherokee while flying down the road. I also tried the clear flood procedure several times with zero success. I did not check the plugs or wires… did not really think they would be to blame right away. I know the radiator could use a good flushing, but did not think that it would kill the Cherokee either. Finally, I didn't order a new computer because I did not want to throw that big of a chunk of money at a problem that may not exist without having had a diagnostic test.

Please do not get rid of my Optima yellow top or Green air filter. The battery should not be too drained from the attempted turn-overs and the air cleaner just needs to be cleaned. I will be leaving all of my tools and some personal effects that I will not be able to take with me on the airplane. I do not know if it matters, but my Cherokee has current registration and insurance. Additionally, I am prepared to make payment over the phone with a credit card…

The dealership called me a week later and told me they got it running: plugs, cap, rotor, wires & injection cleaning. I wasn’t able to pick it up for another two weeks. But once I flew back I drove a rental car to the nearest town to Odessa and had the rental agency drive me to the dealership so I could pay for the services and get back on the road.

Everything was fine… for fifteen miles. However, when the Jeep broke down this time it broke down on a back road. I was taking the back roads to avoid interstate construction. This time fuel poured out from the top of the fuel tank. I won’t go into the details of the freaking weird Deliverance-esque experiences of that evening getting a tow truck, guarding my Jeep while armed, or random meth-lab discovery. The next morning the "tow service" that picked me up a few hours earlier fit me into their busy weekend schedule (yes, the dealer was closed) and with a literally a couple extra hose clamps managed to control the somehow over-pressurized fuel system (wtf?) and got me headed back west. 14 hrs later I made it all the way back to Colorado. Of course I had a huge knot in my stomach then entire way back thinking I was gonna get stranded in the middle nowhere again. This could easily be a B-movie mellow-horror (is that a genre?).

I got back, pulled the codes again and it directed me to change the O2 sensor. I must have changed the wrong one because the light is still on, the Jeeps smells burnt after I start it, and my gas mileage still sucks.

Soooo… since I’m here in Africa for a few more weeks I’ll plan on changing the other O2 sensor, possibly getting a new cat when I get back. I think I’ll take a look at the fuel system too, because the fuel pressure thing has me really confused.

Sorry to ramble on and on, but it actually feels quite therapeutic! :wings:

[brockmub]

Glad that this was a good therapy session for you. Please don't take any offense to this, when you look at all of the "creative" things that you've done to your rig, it's no-wonder that you have some weird gremlins showing up. I'm a firm believer in KISS, especially when it comes to a vehicle that I rely on everyday and for long trips.

That's another reason why I have my old Blazer. A monkey with a shop manual could work on it and the most technical part on it may be a tie between the carb and the broken 8-track deck.

Again, please don't get me wrong, with out people who tweak and change every last bolt on their vehicles, we'd know very little about our machines and what they are capable of. But for me, I'm not interested in stroking the motor, running different fuel maps, or mount a set of 38s when I'm not willing to spend the time to fix the bugs that will turn up in a vacant parking lot. I would rather spend that time exploring, that's why I started this post.

For our next therapy session, I want you to tell me about your relationship with your mother. :ylsmoke:

[nbleak21]

Our departure is less than a week away, so my wife and I decided on a shake down run. Just wanted to make sure that all of the gadgets were working correctly and packing so we drove from Sioux Falls to the burbs of Chicago to see family. We turned on the Droid MyTracks and recorded the short section from LaCrosse to Madison.

http://lh3.ggpht.com/_lBceBoAHK6c/TAOsAwmM1_I/AAAAAAAAAcc/0NOUUdHp6uE/s400/La%20Crosse%20to%20Madison.jpg

Took a few pics on the way of the crazy amounts of windmills.

We also loved coming from Minnesota and literally dropping into the Mississippi valley.

Then visited some friends that lived in La Crescent on the ridge with a beautiful view of the river.

I will post the trip report of our trip to Mexico in the on-going trip section next week.

[T>D>C]

My DD is a 91 cherokee beater with 272,000 miles on it. I bought it used in 2002 with 134,000 miles on it and I drove it to Utah bowhunting 2 weeks later for a shake down cruise. Over heated in Albuquerque and the dealer tried to rip me a new one because I was in a pinch. They charged me $95 just to look at it. I would not allow them to empty my checking account but since I paid my $95, they let me talk to the mechanic. I left there and bought the replacement parts and changed them out in the town I spent the night in.

I live in East TX and I take an annual trip or 2 to places like Big Bend SP/NP in West TX (650 mi) & Manti LaSalle national forest in Utah (1,200 mi). I changed my fuel pump in my garage (had to drop the tank and the metal ring that holds it in is a pain) so I would not take one. I had my alternator replaced in Odessa once and I changed it once in my garage (huge pain on Cherokees). One year, pulling my friends Samurai to Big Bend, I had the gears in my rear-end replaced in Dallas.

So, if you break down, so what? You might lose a day or two at the most. I never lost more than 4-6 hours on any of my adventures due to mechanical problems. As long as you look at it as part of the adventure and keep a positive attitude, who cares? I guarantee you the break down will force you to slow down a little and probably see things you would not normally see and meet people that you would not meet normally (most being descent people willing to help you out).

I carry replacement radiator hoses, heater hoses, and idler pulley, additional fluids and fuses. I would also reconsider the gun, it's not for the little furry animals if you know what I mean...

After that, carry enough food, water and personal gear to stay comfortable until help arrives for the big stuff. And most importantly, have fun!

No worries...

T>D>C

[YJake]

I agree with evrything above.
I would not go anywhere w/ out a extra CPS. but I would also add
a idler pully. I have seen these just fail and your dead in the water.
Its less then 20 bucks and it is small. I even carry one in the Rubicon.

This man speaks the truth. I've had one completely fail and another begin to fail within the last 8 months and am tempted to carry a spare the next time that I go on a long trip. The first one's bearing fell apart causing my Serp belt to fall off on the way one fall afternoon.

Not fun.

The second was making an intense whining noise so I just replaced it before something silly happened.

Moral of the story is, carry an extra idler pully and lots of tools. It is a Jeep after all! (Although my YJ has 145k on it, with mostly little repairs and nothing too major to date!)
