Does it have a posi-traction rear end? This happens when the sider gears or locked up.

You are saying that when you let the clutch out, the driveshaft rotates, the vehicle does not move.

I have to ask this one! Were you dogging it out when it happened?

In the beginning, I was going to suggest that maybe your differential was "popping" because that maybe your posi-traction differential lacked hypoid fluid (needed changing + hypoid additive) or needed to be driven in tight figure "8"s to lubricate the clutch discs within the differential.

After your second response, I am now leaning towards something broken within the differential (not good) or maybe you broke an axle (a little bit better!).
