Rear Suspension Noise

Well Ive got about 250 miles on the Cuda now. She is running sweet. One issue I have is I'm continuing to have a rubber sqeaking sound when I hit a pot hole or go over a speed bump in the rear suspension. Iv'e checked tightened the rear shock bolts and now Im down to the leaf spring attach points new rubber. Im curious if anyone else has had this issue and short of taking it back apart is there a solution to this problem? I guess im looking for an easy fix or someones prior experiences for resolution? Thanks

Did you use Urethane bushings? If you did not use the lube supplied they do squeak.

No I thought of that too so I checked my reciepts and they are just the Rock Auto Rubber ones.
