To break the lower a arm loose from the ball joint simply loosen the lock nut and grab a couple of ball peen hammers. Hold one firm against the a arm by the ball joint and firmly hit the a arm on the opposite side with the other. A couple of sharp hits will break the arm loose from the taper of the ball joint. Then remove the three allen screws and retaining plate from the ball joint on the bottom of the stut. Loosely place the a arm back onto the ball joint with the lock nut and simply pry between the a arm and bottom of the strut. This will pull the ball joint from the strut. Simply tap in the new ball joint and reassemble. Be sure to use a small amount of blue loctite on the 3 retaining screws when reinstalling. Simple to do once you look at it. Hope this helps.
