I have a 70 SS that I've had about 3 years. I hear a squeak as I come over the curb into my driveway. I also hear it to a lesser degree just driving down the road. Things I've done to the car: Replace front control arm bushings with the black polyurethane bushings. Installed QA1 coil over front shocks and larger sway bar. Replaced rear leaf springs bushings with black polyurethane. The black energy suspension bushings are impregnated with graphite. Also replaced the rear shocks with QA1 double adjustable shocks. I had the exhaust system checked to eliminate and interference problems. Again, this squeak is observed when the chassis is unsettled as I drive up the curb into my driveway. Does anyone have any suggestions to pinpoint this squeak? Thanks in advance.

 

For those that followed this thread, I have the culprit to my squeak. I wish I could tell you that I found this myself, but alas, I didn't. I found a thread on the LS1tech site. It seems that with the double adjustable QA1's, that if you loosen them up to 0 or the softest setting (righty tighty, lefty loosey) the sound will disappear. Mine did. Now, I don't have a solution yet, but I know in what direction to go. I'll post the final solution when I find it.
