Either you broke an axle shaft causing all power in the open diff to go to the side with the broken shaft.
You broke your spider gears or stripped the pinion or ring gear.
If it is your axle shaft you must not have c-clips as you tire didn't walk out with half an axle shaft attached to it. I'm not certain offhand if YJs ever came with non c-clip rear axles...
