92 Supreme SL

[Guest]

I just purchased a great condition 92 with 95K and all the records. Put on a new muffler system, but still one thing.. The rear eand chunks over mild ridges in the road. The exhaust shop rechecked their work and we both checked out everything in the rear end and it looks tight. All bushings are there, no hardware missing. The shocks need to be replaced, but the jounce is okay and we cannot duplicate the noise on the lift. Any Ideas??<P>Also, do I really need to fiberglass spring compressor on the leaf to remove the shocks, or can I just use jack stands under the rear hubs to rplase the struts?
