I just bot a 2003 1500LT. When I put it into 4 wheel drive on dry pavement, it started to seize up almost immediately. I couldn't go more than about 20 ft and it felt like it was going to break. Now I know you can't drive on dry pavement in 4 WD for too long, but I thought you could go for at least a few hundred yards or more before it would start to seize up. I think it has a transfer case problem. Does anyone else have an idea on this? I would be glad to hear ghow your burb acts.
