93 C4 rear clunk noise over bumps?

[Vette40th]

My 93 is making a clunk at slow speeds over bumps. The rear has new hubs, leaf srpings, spring eye bushings, shocks are qa1's about 3 years old. What else can clunk back there, before I get into it this evening.

I also have a "clunk". I think mine is the rear hatch. I do know the weather stripping needs replaced.

Besides all of the bushing and tie rod links- you can have some diff side bearing play on the driver side, but I don't think that usually makes much noise.

I'd look at the shocks again. could have loosened up at the top.

I retorqued shocks, wheel bearing spine nut, dog bones etc. I even verfied spare tire carrier was tight. I may be getting old, but it sounds like a tire when you take it off and it slams to the ground on the flat side/tread. Noises are hard to describe.the supension is all pretty new.very few miles, due to Hawaii and deployments...

Exhuast ??? Are the nuts on the muffler hanger at the rear loose?

Nope. exhaust is tight. I think it is the half shaft. I remember when I did the u joint that it had a slight noise to it I could make when it was off the car. From what I know it is a cardboard type material in there, for noise suppression. I have no idea what is in there, but it was loose. Now with the weight of the car, it magnifies it. Thoughts?

Update. Found the problem. I have QA1 adjustable shocks with ZO7 springs. I had the rear shocks set on very soft, 2 clicks. Apparently it doesn't work with the spring. When I bumped it up to 5 clicks, noise went away.. So, a 5 is matched somewhat with the year spring. Too low, and it doesn't work and do its job of dampening..
