I was not talking about the ball joint. I have seen the shoulder on the shank of the bolt to long on those non factory gold grade 8 bolts. Longer then the ball joint is thick. So when tightening the bolt the shank sticks through the ball joint and gouges and squeezes its way into the threads of the spindle. I don't see washers on the gold bolts. The factory bolts have a shorter shoulder on the shank of the bolt then the gold grade #8 over the counter bolts. Just something I ran into myself in the past.
A good strong impact gun should hammer it loose as it was probably install the same way.
