Rear Suspension CRUNCH

I have 01 Hawk with Bilstein Suspension.
When driving over a mild incline, rear suspension compresses and makes a crunching type of sound. I thought it was due to cold springs...now im not sure. Has anyone experienced rear suspension noise. I know the Bilstein is tight...just didnt expect to hear "crunch".
Any comments would help...thanx.

Comments ANYONE??

hard to say. what i would do is grease all of the suspension bushings and see if this removes the noise. you'll have to remove each part and then put grease on the part of the bushings that touch the metal.

good info...thanx
