My '01 XKR has been making a squeaking sound when going over bumps. The Dealer replaced the Upper Arm Bushings which was covered under my extended warranty. They say that it still makes "a klunk" and want to replace the Scock and Shock Monts which will cost me $710. They still don't guarantee that will fix it so at this point I'm not sure I want them to continue replacing things at my expense till they find the problem. Any idea what it could be and why they can't use a stethesope to find out exactly what's causing the squeaking?
Thank you,
Stephen
