Check your universal joints (all 6 of them), and make sure the front differential mount and it's cushion are all tight. If you don't find the problem there move out to the wheels and check the bearings, braakes, and trailing arm bushings.

OK guys, here's my verdict. Mine has been doing this for 3 years now. IT CAN'T BE FIXED. I have talked to several people who said their C3's did this right off the showroom floor. It is a result of the slack between gears in the drivetrain, especially the diff. Have talked to 4 or 5 people who properly replaced every U-Joint and that did not fix it. GM makes the lubricant to add to your diff which is supposed to help stop the noise. I have not heard how it works. Anyone?

I had this happen on a DD and it turned out to be the universal joints. the needle bearings in the joints were completely toast.

Don't forget about a loose pinion yoke on the rearend. If so remove it and turn it 180 and re-install and torque to spec.

I have seen several clunk from this and it doesn't have to be that loose to clunk. JIM
