Clunk noise from under car.

[DegreE]

Ever since I bough my car I've been getting a "clunk" noise when ever I let off teh accelerator pedal. Then again when I give it some gas.

Only does it when I'm driving the car. Sounds ike its comming from the rear more or less.

Any ideas?

Drive Shaft Steady bearing

correct me if im wrong, the preload on the differntial. Put your car in gear and go under your car and see if you can rotate your drive shaft back and forth. That play in the driveline is in the differential, I have the same problem and I'll tackle that another day.

I'll try this @ work when I can get the car on the lift on Monday.


Anything else I should check for?

bad u-joints? Carrier bearing? bad or missing bushings?

This sounds silly, but check your wheel nuts... We had the same type of noise a few weeks back... Took it straight to the workshop (thinking it was the diff), got it up on the hoist, and it turned out to be 4 loose wheel nuts :nono:

i would check the diff mounts and the pinon bushings. i had an rx-7 that made the same noice and sure as shit that was it.

My lug nuts are tight, I just took my wheels down to swap my sawblades and tires to the correct side. I torque all my lugnuts to 80ft/lbs.

Yeah I have a feeling it has to do with the differential mounts.

Trans. mount, engine mounts, carrier bearing, loose pinion nut, worn bushings. Just get it up on the lift, and check everything. I'd start with the trans. mount and carrier bearing.

i would 2nd bad u-joints. my old pickup had the exact same problem. every time i let of the gas it would clang. i change the u-joints and no more clanging. they are a bitch to change just to let you know.

subframe bolts...

the spherical bushings in the rear hubs go out and will do this as well...
