Did you check all your mounts or do you feel its definately driveline related?

Control arm bushing might be worn. Or you could have a loose bolt on one of your CA's.
Loose mount, motor, tranny....
*edit. I had a couple of loose bolts on my CA's a while back. Thought my "clunk" was DL related, not so was the Control arms..

Clunks could be anywhere.
I'd check all the suspension links for slop. Check driveshaft splines for looseness. Check U-joints in the driveshafts. Check the locker for something broke or loose. Check lug nuts to make sure they're tight. Check shocks.
Basically, crawl underneath that sucka, and wiggle everything.
If that don't work, have someone else actuate the clutch with you nearby (or underneath) and listen & watch to see if something jumps out at you

ill check my contral arms. i thought the u joints would fix it. i have looked on google and it seems that this happens to alot of tj but no sites had the same two answers as a fix. the noise is driving me insane. if i let off the gas and shift very gently i dont get the clunk.

When you normally engage the clutch you are shifting the power from the engine, thru the tans & tcase, to the rear driveshaft, which in turn pushes the frame (and body) forward. Since it's got to push the vehicle (thru the control arms), your noise could be anywhere. When you drive particularly carefully, you are also minimizing the suspensions cycling and the contol arm's movements.

wish it was a seatbelt. i jacked the rear end of my jeep up and in nuetral and in gear i cant get i loud clunk. i can feel a slight amount of play in the splines of my rear driveshaft, when i say slight i mean very slight. is this normal?
Where do you live? If it's close to Puyallup I could take a look at it and help diagnose it.
