This past Saturday I took my 1990 Blazer with a 4" pro-comp lift and 33's down a few muddy roads. It worked like a champ all day, not a single hiccup. I drove it to my parents house to ride with my brother in his k-5 for the nite. We got to my truck around 9 hours later, and when I went to move it, reverse was grinding horribly. It was also making a racket like the hubs were still locked it (it still has the factory auto-locks). I crashed on my mom and dad's couch for the night and the next morning took it for a spin. The reverse grind is still there, but now it is starting to grind in drive when the throttle is pushed over a fast idle. I did push it backwards to unlock the hubs, one did open for sure, but the noise is still there. I have talked to some people and they have suggested the transfer case is to blame. I hope it dosen't take much to fix because I'm stuck driving my grandpa's Jeep Cherokee untill the K-5 is road-worthy again. Please help me get out of this MOPAR!
