Check your fluids. Change them if necessary. I believe you can have your transmission "flushed" also if there are too many contaminants in there. You have your rear diff, transfer case, trans, and front diff's to check and or change.

Perform the scuba mod. Which is to relocate the breather valves for the rear diff, rear locker, trans, transfer case. Search "scuba mod" and you will see a stick thread that tells how.
