I'd check the ring and pinion. Jack it up (chock the front wheels), pull the diff pan, put it in neutral and spin the driveshaft with your hand. Check the teeth on the ring and pinion for a chipped tooth.

If that doesn't work, you might have trans problems

feel like its coming farther back then the trans its either the rearend or the carrier bearing hard to get a day off to check it out

U checked your u-joints yet? I always check those first sign of trouble. Then move to the next possible.

When I had my posi unit put on at my brothers shop they found a piece of my gears missing and I did have a little slip as well I would address it soon before it messes up all of it.

i had a few chipped teeth on my ring gear and when you let off the gas and coasted without load on it it sounded just like a bad u-joint clunk

Yeah I know...I had to have my rear end rebuilt last summer because the pinion bearing went out and then metal shavings wore down the gears...total cost was $1100 I should have just bought a 14 bolt then, but I didn't know enough about the swap at that time...
