Clunking Back End

my 91 RS occasionally clunks when I take a corner or hit a bump. I also noticed that when my car is sitting still on a flat surface I can push on the quarter panel and the body of the car can move back and forth but the rear axle stays in the same place. What would do this? I there a panhard bar bushing or something thats gone bad?

Re: Clunking Back End

Yeah, check the panhard bar, bushings and mount brackets.

Re: Clunking Back End

Hey 91camarolover. Agree, it sounds like a potential bad bushing or loose bolts.

The stock Panhard on these cars is a weak link even when everything is tight. An aftermarket Panhard is one of the first and best upgrades you can do.

Give us a call if you need tech help.

Have a good weekend.
