Trying to remove the front control arms to install Energy bushings. I cant get the ball joint end of the arm separated from the knuckle. I was banging on the end of the ball joint bolt, but it is starting to deform, so I think I need to stop that. Trying to whack the arm, close to the ball joint, but no luck. I thought about using a tuning fork, but I'm concerned about damaging the ball joint rubber boot. Any suggestions?
