Lately when I have been driving, I get a hard clunk in the rear of my gti when I run over the expansion cracks in the highway, or speed bumps in a parking really make the suspension sound off. I believe it's coming from one or both struts, they feel fine when you do the strut test and there is no oil leaking out. I am still running a stock suspension from 96 and it seems to be in great shape with only 70k miles on it. The strut bolts seem very tight, and I feel no play in any bushings, you folks have any ideas? Thanks in advance for any help.
