so long story short a little more than 2 years ago i had my transfer case go on me. every time i put any power in reverse it would seem to drop out of gear and have a nasty grinding noise. a snap ring broke on the shaft and essencially caused a shitload of shrapnel in it and i had it replaced with a gm remanufactured unit. so fast forward to the past couple weeks, had the same thing happen from what the tech told me. i dont care about fixing it, that isnt the issue. my issue is if anyone has heard anything like this problem in other nnbs trucks and if they had a lift/tires/tune/gears etc. i have looked around a couple forums and have found nothing. i just dont see what could cause a second transfer case to blow up on me or how/what can be done to strengthen so so called snapring from breaking.
