i played hard this weekend and then driving down the road the wheels locked up in 2wd. towed it home and in 4 low the truck will fine. in 4 hi or 2wd, it locks up at 10mph. jacked up rear wheels off the ground, the transfer case tries to move the front drive shaft. and ideas? transfer case or transmission issue?

 

Sounds like transfer case issue, which tcase you have?? Hell what kind of truck is it??
