Re: Full Time 4x4 T-case, only turns front shaft!

If it is a full time case (NP203), and you tried to move it with the front hubs unlocked, what you describe is exactly what would happen. The front shaft would spin and the truck would go nowhere. That is normal operation for a 203. An '85 would have come stock with an NP208 though.
