Has anyone found a solution to this problem yet? I've been having the same problem for the last year and a half. Only when mine is in 4wd, and driving under a medium load, like mud or slushy snow, doesn't matter if in a straight line or turning. It makes a loud pop and acts like it's kicking in and out of 4wd, no rhyme or reason, could be fine for 5min, then suddenly starts doing it randomly. It's almost left me stranded while towing my ice shack across a lake in shallow slushy snow. It went to the dealer and they adjusted the cables, but did not change anything. Seems to be something broken in the front diff if I had to guess. HELP!!!
