Over bump clunks?
Whenever I go over bumps, I get this really low bass sounding clunk. I've gotten under the truck to hit things to see what may be loose but I have nothing. Any recommendations for things to check that I have not thought of? Or are these just truck clunks? It sounds like something is loose more than the suspension rebounding.

Also if you can, raise the entire front end onto jack stands by the frame so the suspension is hanging loose and see if you can find something that is loose and banging around. But PLEASE...use jack stands...would hate for you to crawl under there and wind up a pancake cause the truck slipped off a jack.

my guess would also be radius arm bushings. I had a couple of 79 pickups that did the same thing. I discovered that the old rubber bushings had seen better days. They weren't too bad to swap in new ones... went with poly bushing while I was at it, made a big differance.
