03 z71 transfer case issues

My neighbor has an 03 z71 truck and somehoe all the transfer case fluid drained out. He had it towed and we just refilled it with royal purple fluid. The noise went away at startup but when its in gears and he moves back and forth it sounds like a chain or something is broke or loose inside. Any suggestions or does this thing need to go to a shop? Thanks

Not sure excatly what goes wrong internally, but two of my friends have similar year trucks that had the same thing happen that you describe. One actually had a hole in the side of the case. Both had to have the T-case replaced.

 

Check passenger side of transfer case. I've seen 4 chevy truck transfer cases crack there.

 

If it sounds as u say. He needs to find a junkyard transfercase.

 

you guys are thinking of the 2500 transfer cases.
