I have a 2001 ZX3 with about 54,000 miles on it. At 24,000 miles I installed Eibach Pro Kit springs and Eibach Pro Dampers. Everything has been peachy up until early last fall. I began hearing a creaking noise coming from the front of the car. It was very difficult to hear/produce at the time, but I knew it was there. During the winter months I started to hear it more often and now it's spring again and 70 degree temps have returned and it is extremely loud. The noise only happens on right hand turns (weight transfered to the left side of the car), ESPECIALLY long sweeping right handers. Usually below 20 mph is when I hear it the most. Going over driveway entrances at 5 mph or less also produces the creak.
If I open the door and jump up and down on the drivers door sill, the noise is easily reproduced as well (bouncing the passenger side results in nothing, btw) The suspension still feels extremely tight and safe at speed, but it is just noisy as hell. It sounds like a dry bushing is creaking perhaps?
Any input? Things I should check before I take it to the dealer?
