I know there are lots of questions about this but mine is a little different. Whenever I am decelerating I here a constant clunking. Since it is only when there is no load on the drivetrain, I think it is either the driveshaft or halfshaft u-joints. Anybody ever have this happen to them.

i assume this is a 240,260 or a 280z ,if so it could be the rubber snub block on your rear end. if this fine, it is you half shafts

I had the same thing on my front wheel drive tercel (winter car). I found when I was coasting with no power on the wheels it would clunk and wobble like crazy I just replaced my bearings and cv joints.
