Supposedly, another cause could be the tcase clutches and the fix is replacing the tcase fluid. My 00 4x4 has 67k on it; I replaced the fluid with synth at 30k, and just did it again in May 06 at about 65k miles. The noise went away both times. My thinking is that that awd engaging through the tcase on demand must wear the fluid out fast. Try changing it with synth or at least make sure that's what gets put in with a new tcase. It might work.
