Get the grinder and cut the nut off. What a job these thing's can be. Take a brake and then go back at it.
Need more info. What exactly is stripped? The nut spinning on the ball joint or the ball joint in the control arm?
Yes the top nut. Have had to cut nut's off before that where stripped. Know it is a job. But we have to do what ever it take's. Have cut them off with a torch all so.
Got you. Yes cant grind that off sorry. Thought it was the nut on the bottom you where talking about. Yes that is a real pain. Use the ball joint puller to push the stud out of the spindle. Then rap it with a hammer while turning the top of the ball joint. Hope that helps. It might screw out if the bolt is not connected to the spindle arm.
