I let out of it, put it in 2wd and rolled a little ways and started giving it more throttle and heard the pop again. Went on home and babied it for a few days and decided to try it in 2wd again to see if it did it again. No more pop but im scared to try 4x4 again. All i can think of is maybe something in the transfer case slipped. Like maybe a gear or chain skipped a tooth. I dont know if these things are chain driven or what. But, like I said, it has me pretty nervous to try 4x4 again. I am assuming that I got the pop in 2wd because everything probably wasnt all the way unlocked.

But this was a long ways from a slight pop and it was in the middle of the gear. How solid were the pops you experienced? I would say mine felt like someone hitting the bottom side of my floorboard with a good sized hammer.
