Time for name that sound...
 

When I'm driving my 98Z if I apply the brake and then give the car gas, I hear a pop towards the back of the car. It happens when I go from a stop, it's like some pressure is built up and released when I go. The funny thing is I can apply the brakes, then release them and coast, then give it some gas, I hear the pop from the rear. I thought it was my torque arm and I changed the bushing, but that didn't do the trick.

Any ideas what I should be checking for?

is it a pop? or more of a clunk?

Somewhere in-between... I guess more of a clunk. It happens when I give it gas, occasionally on a shift. (I have an A4). But it almost always happens when I'm coasting, hit the brake, then give it some gas.

transmission mount...

lower control arm bolts...

Loose bolts to driveshaft caps and your pinion yoke. Possibly a bad cardan joint, excessive play in the rearend. Just going over what hasn't been covered.

Thanks, I'll take a look underneath and check those out.
