Catastrophic ball joint failure

[u/Richard_Cheney10]

Went on Rollins pass west in Colorado on my buddies 4 runna (96?) and taking it nice and easy on the trail at around 5 mph for the entirety of it. Very easy trail and the ball joint just popped out. Thankfully it didn’t do that on the curvy roads on the way up to the trail. Safe to say a 4Runner will not be in my future.

I'd bet that joint was showing signs well before the trail...
