If the light is on, that means the transfer case actually shifted into 4x4.

With the switch in 4x4, and the light ON, jack up the front wheels off the ground and spin each one. See if the u-joint behind the wheel spins with the wheel. It sounds like one of your hubs is hanging up and not really locking.

It may be worth taking the shift motor off of the transfer case and inspecting it also.

I believe it is possible for the motor to break in such a way that it still moves the switches but doesn't actually turn the shift cam shaft. The switches are what reports back to the 4WD control modules that the shift has completed.

Good point David, if the square drive rounded off, or something else broke, maybe...

I seem to recall someone reporting that just that happened. The square drive rounded off of the shaft, or the motor, I don't remember which. It's probably not very common, but worth checking.
