I have a nasty grinding/clunking/groaning noise in the rear. It only does it after the car has been driven for a while. I recently did rear shock mounts so I know it's not that. It only does it when turning at a relatively low speed. It's been to two mechanics and neither has been able to pinpoint it. The rear subframe bushings look good and I don't think it's wheel bearings. Ideas?
Need help diagnosing a horrible groaning sound

Would they do that only when the car has been driven for a while? How can I check half shafts? I'm assuming one of the two garages it was at would have figured out one of those two things since they are fairly visible. Differential?Comment

Could be the differential. You said turning, where each wheel would be spinning at different speed, which could cause groan.
Might want to consider it.Comment

The car makes it possible, but the driver makes it happen.

All of the above can do it....I'm contemplating just replacing the axle shafts, differential, and wheel bearings. It is after all a 21 year old car and I'm sure the second I replace one item a new one will poop out. I'd rather do it all in one fell swoop than constantly be finding a new broken thing.Comment

You can do it that way, but unless you are using new parts there is a chance that the result will be worse. I'd start with the wheel bearings. And I'd put the car on a lift and try to find the source of the noise if it was still present after wheel bearing replacement.The car makes it possible, but the driver makes it happen.

I would of course use new or rebuilt parts. I've had the car to two mechanics and neither was able to effectively trace the sound. It only happens when the car has been driven for a while.Comment
