AW4/Driveline thump when starting or stopping

Lube the slip yoke, it takes about 1/2 hour to do. You either already have anti-seize, or you need to buy some.

Does any of the hardware need to be replaced when doing this? My '00 does the same thing...

My vote is spring wrap. When you brake, the axle rotates top forward, spreading the leaves ahead of the axle. Let off the brake, or accelerate, axle snaps back, with a nice deep clunk. I fixed mine with spring straps-originals were rusted off. Got 'em at NAPA, weren't much money. I will add that I need new springs, Got it 3 years ago with 100k on it, was already making noise. Seems to be no rhyme or reason to how or when these things wear out. My '92, 202k miles, no clunks or bangs, springs still shaped correctly.

i would vote no on the spring wrap, i have new RE spring pack not related. lubing all my points on the drive train solved the problem.
