Same thing happened to the shop when they put the locker in Bushwood - finished up, went for test drive, made a slow u-turn, axle and wheel exited the Jeep.
The owner of the shop said it was the retaining ring (?) He said that there was another type of bearing that did not rely on the ring, but that it was standard for the Jeep. He replace the bearing (on both sides) with the other style... no, I don't know how to source that bearing. I can call him and ask if someone here can't answer it first.
