Hey there, this thread is 9 years old

Highly recommend starting your own thread, and detailing as much of your issue as possible, and detailing as much as you know about the vehicle.

 

Unlock the front hubs and see if it will roll under power in rwd. Then pull the rear driveshaft and do the same thing but in "Front wheel drive". If it will do one and not the other you have narrowed down your problem. If it won't roll then you have eliminated 2 major working parts and are down to the trans and transfer case.
But yea will probably get better help by starting your own thread in the newbie section.
