Just inherited a pretty nice '91 4WD pickup. Today, for the 1st time, I attempted to put the truck in four wheel drive (we're having a bit of an ice storm), but no luck. The transfer case shifter won't shift. It'll move a few degrees in all directions, but won't come near engaging. The previous owner had a clutch installed somewhat recently, but was told that 4WD had worked since then. Any comments greatly appreciated!

 

Does it have a body lift?

 

It doesn't.
