Mine is 97 with factory diff lock. I am going to check on:
1. Rotate tires to see if it makes difference.
2. Squirt couple grease to xerk fittings
3. See if exhaust tip angle change makes difference.

I will let you know.
Thanks.

I had the same problem on mine after I put in the 2.5" lift. It only happened on long trips at 65mph+ and when I let off on the gas. Toyota thought it was the diff and replaced the pumpkin (on warranty). It turned out that it was due to the changed pinion angles; a set of upper Slee rear control arm extensions should alleviate the problem. I've not had the problem again since I installed them.

Good Luck,

Matt
