    Drivetrain whine - FG434 + Entertaining Pics

    Just an update for those that helped out. I dropped all drive train fluids (again haha) and went with Gulf Western (Australian) full Synthetic 80w90LS across all components (talked to their tech department first to confirm suitability). I can confirm that running 80w140 does impact...

    It's sapping 1 of my 3 horsepowers haha Yes cold doesn't make it go faster like it did on many previous turbo cars. I put it down to engine air density vs fuel, ie air increases, fuel doesn't, on a diesel not gonna help power I guess if i was rich could put a 90ish grade full synth in the...

    Oh, on another note how much does drivetrain oil type affect performance (and intern fuel)? I ask as since going to 85w-140 hills that use to hold speed now loose speed. Only change is oil grade

    Asep, Interesting you've got the same thing going on. Sounds like it's doing your head in. Did the rear Uni's tonight and also pulled the front shaft which needs a new slip joint. While appart I spun it up to 90 in 5th and used the handbrake for load. The Whine could be heard so 100% not the...

    Diff play seems very minimal.

    I put 85-140 in the transfer and I think it's less prounced, haven't driven for hours straight yet though. Going to out the same in the diffs. I haven't drained the gearbox oil. It's always had a whine since I got it, drained fluids then near 1 year ago and all were very good. But yes makes...

    Cheers for the reference point.

    It's a SWB so not centre bearing, transfer straight to diff. ?

    Yes I thought it looks pretty good. Now I've got 85-140 in it, is that a problem if it's good? Spec is SAE90. On stands I got under the back and the noise was so pronounced in the middle of the truck, it just didn't seem to be from the diff. The gearbox bloke recons once on stands with...

    A bit of an update on this. I pulled the inspection plate and to me it all looked really good, almost new. No bits came out on drain, the year old oil looked really good, and magnet had only a small amount of filings, hardly noticable. I couldn't pick up any side load play or any wiggle play...

    Thanks for the guide, I'll inspect on the weekend. When I changed the fluids after purchasing all were pretty clean and nothing on the magnets. I put in Penrite 75w-90 Trans Gear in it (Gearbox too, I went of what guides indicated to put in). This sounds like it is probably too thin. It's...

    That's not a bad idea, I've seen that big inspection plate. Will I need to drop the fluid before taking that plate off?. I talked to a gearbox/diff shop today and the bloke said that it won't be the gearbox if it's the exact same in 4th and 5th and thought it would be most likely the diff...

    Thanks for the input guys. I'm hoping it's just helical cut gears in the transfer that I now notice more. I did a bit of testing and it's only apparent with load against the motor, either in acceleration or deceleration. So clutch in it does nothing, Clutch out and in in Netural does...

    Cheers, while it stops with no load (clutch in) I'll certainly try neutral on the box and transfer and see.

    FG's in Action

    I put these in my tech thread but figured they'd fit here nicely :) Holes look much smaller way up in a cab over. The rear left wheel lifted when I winch back out and slacked the winch for a period. The truck wasn't stuck, I just didn't want to drag the fibreglass body through anymore. Rear...
