I've got a 2002 Chevy 2500HD and it doesn't want to move. Got it pinned down to the transfer case. It shift from Park to Drive just fine, Wants to move, but it won't. Has anyone had a problem with this? Looks to be expensive to replace the transfer case. Any thoughts???

why do you think its the transfer case and no the trans or rear? i would take the rear shaft out of the tcase and see if you can move the tires
