After reading all these posts, I'm more inclined to say it's your 4x4 computer module. From what the guys have written here, I'm assuming that the 4x4 computer module controls the 4x4 system by managing it when you select Auto, 4x4 high, or 4x4 low. I too get the noise but only after I select high or low. When I'm in Auto mode, everything is quit and smooth (which tells me that the computer module is working and engaging the proper gears when I select them). It sounds like your mechanics made a mint of money when you showed up because from the sound of it, they're chasing their tails by replacing what they 'think' is wrong, not 'what' is wrong.... I'd go to a different mechanic if I were you since they're just after your money....
I tend to agree with this. I recently drove mine back and forth down a 4000 foot long driveway to pack down the 12" of snow. I selected 4x4 high for this and the first time I got to the end and turned around on the dry pavement there was a lot of clicking and lurching which is normal when 4x4 is manually selected. After this first time I just switched to 4x4 auto when turning around and everything was quiet. The module could be defective leaving it in 4x4 high without an indication. Not sure how the shift motor plays a part in this but if it hangs up it could possibly have it mechanically stuck in 4x4 high.
arlind04 you have not said if your 4x4 works fine otherwise or whether you have AWD or 4x4. When they replaced the rear end for the suspected noise I sure hope it was not an open rear end (no limited slip).
