Hit the transition to a dune at speed, el snappo. Been on my car for a couple years, full hydro, 40s. Nothing else broke, studs were all good, and properly torqued, stops were correct (although I don't see where that would be a factor with this break) knuckle itself is still good to go. When the upper went it put all the load on the lower pin and bearing, bending the ear way up. So now I have to cut the ball off the housing to get the birf out, so the housing is wasted as well.
