a-arm bolt?
Are you talking about the ball joint??? You may be able to chase the threads w/a thread chaser if they arent screwed up that bad, if not (and your talking about the ball joint) your gonna have to pull the arm off and have the ball joint pressed out and a new one just pressed in. You wont have to remove the spring itself, just unbolt the strut. Just had new bushings and lower ball joints pressed in on both sides, $100 in parts and $100 bucks in labor for a local shop to do them- Got fricken raped on labor
Hope this helps-Jeremy
