My car never had the clunk from the rear that a lot of folks complain about, up until I went to the track and blew out my diff cover. I since replaced the cover and have the brace. When I was putting the new cover on, I noticed that the driver's side rear wheel had a slight bit of movement to it. All of the controll arm bushings, ball joints, toe arm bushings were solid and showed no movement. I havn't had much experience with halfshafts and am wondering if this is where my newfound clunk is coming from, as well as the wheel movement. I have since put 1500 miles on the car and doesn't sound any worse. I have done a search on the clunk but havn't come across anyone talking about wiggling wheels.
