Ok, so i'm gonna start off here by tellin you i blew out my first 12 bolt rear end. From what i read, seems to be commin. Well, when i blew it out, i had no other way of gettin it home other than pullin the rear shaft and drivin home in 4hi. I did ruffly 45 for about 15 miles. Along the way though, i noticed if i was crusin, it'd be alright, but if i'd try to accelerate a little bit, i'd get a vibration from hell, and what would sound like ground out gears from either the front end or the transfer case. I'm sure someone else has had this problem. I'm gonna be gettin another blazer to swap the engine trans and transfer case out of the one i have into the other. So if i had the transfer case out of the one i have now, would it be worth crackin it open to see if that's the problem?
