Default on/off rear end clunking noise, _but_ I have all new mounts, sway, etc... already STFA

I have new engine mounts, trans mounts, dts, rear diff ring plus 034 bushings, Stasis (Koni) motorsports and h-sport sways. When I go from coasting to accelerating and accelerating to coasting, I get a loud clunking noise from the rear end. I tightened all the bolts I could, repositioned the exhaust, and I still get the clunking noise. Ideas?

is there stuff in your spare wheel well instead of a spare?

Default the upper and lower shock mounts need to be tightened with a jack under the upright.

at or near ride height.

This may be causing the clunk.

No. Spare is in place and tightened down.

The suspension hasn't been touched in a long time. I will verify that the bolts are tight though.

Default I had that once after a dealer tech did a bearing replacement. Left a rear sway bar bolt off.

Look again.

Default Some bolts worked themselves loose on the rear diff rear support bracket

I tightened the allen bolts back down and the problem went away. Whew...
