Ok guys, I am having an issue that the dealer cant figure out. Since day one, I noticed some creaking noise coming from the rear suspension when going up or down the parking garage at work. It is a cork screw garage so the car is at odd angles. The creaking can also be heard when going over speed bump but its not as noticeable. I tried removing the rear strut tower brace but that did not seem to help. The first time I took it in to the dealer they said I had a bad shock and replaced with a new one. The problem went away but came back after about 2 weeks. I brought the car in again and the retard techs just tightened the strut tower bolts and said it was fixed (even though they never took it for a test drive). So, I am at my whits end with this problem and need to figure this out on my own since I cant get anyone at the dealer to troubleshoot correctly. Has anyone else experienced any weird noises coming from the rear suspension? Any suggestions on what I can try next?
