clunk in the night?

[chief44]

i got this clunking noise whenever i accelerate or de-accelerate. I thought u-joints right? Nope, replaced them both, still have problem. Anyone have any ideas? Noise is coming from rear of car.

Control arm bushings maybe. Or Trans mount?

My thoughts are exactly as reddy said.

give your rear sway bar a nice kick it shouldn't move. it coulod be the infamous snapped rear sway bar.

According to my tuners, they all have a little play in the drive-lne. Mine does it also letting off and getting on the throttle at times. Mine is in the rear, it has a little play.

In addition to motor/trans mounts, I'd check the crossmember bushings.

Good luck.

it could be bushings or a broken pinion ring tooth, could be to much backlash, broken sway bar, or you could be dragging somebody or something Are you missing any animals?

jack car up so the rearend suspenion and all is hanging then try moving the rearend side to side also check bushings, check gas tank make sure its secure.

Is it a constant clunk every so often or does it happen once per downshift/upshift?
