Guess what broke...... Centerforce Dual Friction + slicks

Are you saying that the end of the axle that is stripped was messed up before this incident and not a factor?
Correct, happened 15+ years ago and I just swapped out for the single spline side gears.

Looks like the suregrip/powerlock came apart.

I either didn’t install the seal deep enough in the housing or didn’t press the bearing on far enough.
