i cant find this this for the life of me. there is a pretty loud knocking sound when im driving. i know that it is coming from my driver side rear wheel. i think that its knocking at a certain point because it seems to be a knock for each rotation of the wheel. the knocking goes away when i apply the brakes. i have a stock GTA set up with C5 Z06 rims with 275s out back so i dont think its rubbing.
thanks

 

hey i know this thread is two years old but i have the same problem and was wondering if you figured out what the problem was. thanks

 

If your sound goes away with braking id start by inspecting the brakes.

 

check the bolt to the panhard bar? might be loose.

btw are you running discs or drums

 

Yeah, more info is needed. If you have discs and it occurred with every turn it could be a warped rotor or the clips are not on the brake pads. start by jacking up the car and making sure all bolts are torqued correct and the sway bar end link is not rusted or cut apart. Could also be a broken belt in the tire?
