His hopping looks like it grenaded the u-joint on the axle shaft which pushed out at least one ball joint in the process, and led to the failure of the other. The fact that the knuckle and hub was no longer attached to the stub shaft is what tells me the u-joint likely is what went.

This is also why you run ball joints where the upper ball joint has a snap ring and steel/iron knuckles - the snap ring tries to keep the upper ball joint in the C, which prevents the bottom from pushing all the way out, and thus knuckle and hub stay attached to the vehicle in the event of a u-joint failure. The steel knuckle resists stretching/bending/cracking better than the stock aluminum knuckle.

I'm considering going to steel ball joints when I add a lift and bigger tires. What brand do you like for a JLUR?

It’s worth saying that, at a glance, this Gladiator appears to be modified with larger wheels and tires compared to a stock Rubicon. Larger tires are heavier, which burdens the rest of the driveline and increases load and stress, which have been specifically calculated at the factory for the stock wheel and tire package. This is important because of the type of failure that the Jeep suffered...
Just a word of warning: larger tires and heavier wheels are dangerous! /s

Dynatrac or Teraflex for ball joints. Dynatrac are more expensive, but you can rebuild them without removing them from the axle. Teraflex are cheaper but when they're shot you gotta push the old ones out and replace them. Both have snap rings on the upper ball joint.

For knuckles, the Mopar steel knuckles or Reid knuckles.
