My 97 has started doing the same thing at 165k miles. Starting off uphill or under any load or moderate acceleration, it will pop and clunk until it gets into 3rd gear, and sometimes when making a turn. Since Bravada AWD operates much like a positraction unit, I expect it has something to do with worn clutch packs.

However- with 165k, I'm not in a hurry to fix it as the truck itself isn't worth the expense of replacing the transfer case. I'll drive it till it quits, then I will junk it. It's been a fairly troublesome and high-maintenance vehicle anyway, especially compared to the K-car and the Custom Cruiser wagon.
