If a rear caliper locked up, only one wheel would be stuck and if you were driving, it wouldn't have enough force to really lock up the wheel completely. They generally would get stuck after you stepped on the brakes, they don't just "lock up"

Sounds like your LSD didn't have any fluid or was very low and heated up too much.
