I've had an annoying clunking noise coming from my the rear end of my 98 Camaro for quite some time now. Over anything besides glass smooth pavement there is a clunk or loose wheel thunk type sound. Pretty sure that it's coming from the axle/diff. There seems to be quite a lot of play from both axles. I've heard that a certain amount is normal in a c clip axle but it seems excessive. I've ruled out all of the simple stuff like lug nuts, lca's, sway bar, end links. Any recommendations for a local shop that can fix this? I'm thinking the broken axle but am open to suggestions from beyonders who have had axle/diff related issues.
