Differential Main Gasket

[DeadpaN]

So I was thinking of replacing my diff. bushing, but rather than remove the whole thing, I thought hey I'll just drain it, pull off cover and swap bushings.

Parts needed: gasket-oil-new bushing.

Does this seem feasible anyone who's rebuilt their differential? Or have I been smoking to much.....again?

should be feasible. i would also get some Permatex® Hylomar® Aerosol High-Temp Gasket Dressing or equivalent and also new drain/fill plug washers.

i think that this bushing above is the problem i have been looking into. When i go over a speed bump/driveway at an angle; or let the clutch out with any amount of force i hear a stretching and creaking from the rearend. Then it stops as i drive. It wont come back (or at least i cant hear it in 3rd,4th,5th gears. but 1st,reverse, and sometimes second creeeeak? Also when i let off the gas quickly the car lurtches forward a little (sometning loose?), and is worse w/ac on. The easier i am the less i hear it! :cool: Would the bushing cause this? It is cracked so i am gong to replace it. Any advice or problems would greatly be appreciated.

have a friend that can sit in the back and try to get a better idea where the sound is coming from for sure? i'd check the parking brake cables (typical creaking points), sway bar end links and brackets, trailing arm bushings or possibly subframe bushings, upper shock mounts ...

any change in noise when turning vs going straight?

i can't imagine what would cause it to lurch when you take your foot OFF the gas, that's an odd one.

its a small pull. like something holding the drivetrain is loose

might want to take a look at the guibo and/or center bearing as well.

Having done both a few times, definitely the way to get at the diff bushing is to take the backplate off. You'll need a press to get the bushing out though. And second the high-temp liquid gasket stuff, that works great.
