I just had a shop swap rearends in my 86 iroc.Everything seems fine except for a pop or clunk coming from the rear only when I turn left or hit a sharp bump going under 30mph.The noise wasnt there before but these fools messed up one of my wheels so bad I wount take the car back.It sounds like a spring is moving around or popping.The noise seems to be on the passenger side rear.If I rock the car side to side in the rear sitting still I can just barely hear the noise.Everything I can see is tight.Maybe a spring isolator? they reused the old ones.thanks

 

Are you sure they put the spring isolators back in? Also check your wheels and make sure they aren't loose or something.

 

from what I can tell with the car on the ground,the spring seats are in there.All the wheels are tight.

 

my problem was a broken sway bar end link on the pass. side rear.I did a search and found someone else with the same problem,went out and looked again and sure enough the bolt is broke.

 

I just did a rearend swap yesterday and have the same problem. I KNOW everything is tight, and I know I installed the springs with the insolators on them. I was going to check today and make sure the springs are seated correctly.

 

I thought you just said you found your problem? Wasn't that it?

 

yeah I found my problem(end link),It was someone else with a similar problem
