GenIII Limited Slip Diff

[Worshington]

Hey Gang,

So I was goofing around on the way home from work today in my GenIII, and I decided to put it in a cross axel to educate myself on the capabilities of the LSD on my '02 Monty Limited. I could not get it to engage! I was wondering if anyone had some magic techniques for making this thing work. I tried a few different things…the rear passenger tire kept spinning while the rear driver side tire had plenty of grab and remained motionless.

-I tried keep the tire spinning at a slow and constant rate
-I tried revving
-I tried applying the hand brake lightly
-I tried applying the hand brake forcefully

Anyone have any insight on how to get these things to perform on demand?

Are you sure it has an LSD?

I believe all 01-02 GenIII's came with them as standard equipment in the Limited trim. Mine is a Limited…I bought it under the impression it had the LSD.

When was the last time the fluid was changed?

 

[Worshington]

The truck has 175,000 miles on it…I've put 40,000 on it. I haven't changed the fluid, but it doesn't look too bad.

IIRC they are a torsen type. These might help.

Changing the fluid would seems like a logical place to start.

To get my LSD to engage with one rear wheel in the air, partially applying the e-brake (to pre-load the LSD) while modulating the gas pedal works.

The Mitsubishi LSD used in the Montero/Pajero is a hybrid design using a helical gearset (Torsen, Eaton, etc.) and a clutchpack. The gearset designs are stronger, but do not function under free-spin since they need some torque on both wheels. The clutch pack was added in case of a free-spinning wheel to heat up and engage enough to provide torque for the gears to lock.

The double check is to look for HYBLID LSD on the back of the rear differential case. Some have said that all 01-02 Limited models had the LSD, but that would be the only way to confirm it was not swapped with another one. (Some have swapped LSD into 03+ models or swapped to XLS 4.9 gears)

Need more junk in the trunk- make it lift a front wheel instead :ylsmoke:

The diff needs servicing one way or another. The oil may look good but what sort of oil is it?

 

[Plumberjohn]

double check the diff, my limited does not have an LSD. its an '03

 

[Plumberjohn]

the Diff has a code on it. I cant remember them right now, but the Limited has one diff, and the XLS (?) has another. I believe that the XLS has the LSD. can anyone confirm?

 

[Offroadmuch]

Can someone with a confirmed Limited Slip diff take a pic of the tag so I know what it looks like? I will be checking mine now that it is up for debate....

I haven't owned a Gen 3 with a Limited slip diff but Mitsubishi has always used a bright orange sticker much like the locking differential sticker.

HYBL1D LSD

Should have a LSD.

03-06 does not. As Far as I know all 2001-2002 has the LSD.

The fluid clutch portion is integral to the diff. I.E. not serviceable from my understanding.

You can left foot brake to help it engage.
