Mine has a squeak/chirp sound coming from the rear also... I think it happens mostly when I'm on the highway traveling at speeds around 50+ mph.

I'm guessing it's bushings related. If so, I'll just have to add this to my list of things to do. Look for me to post questions about this in the near future <img src="/forums/images/graemlins/smile.gif" alt="" />
