Same here....sounds like a knock under my seat.[/b][/QUOTE]
If it's a thumping or knock under your seat, that could be the leaf spring hanger bushings that are located right under the passenger doors in the rear on each side. Those bushings are easily replaceable...one bolt and washer on each side, drop the leaf pack, and replace the bushing. I have the same knock, just too lazy to get around to changing out the bushing
