My ball joints on both front lower control arms are busted and the suspension is making a clunking noise over road imperfections and small bumps. I searched the net and found a few lower control arms with new balljoints installed (complete new arm), for $200-250 each. I was just wanting to replace the balljoints but have not found the ball joints themselves. I am assuming that these are dealer only parts. Local auto parts stores don't even carry them. I was just wondering if someone has already replaced their ball joints or front lower control arms and where did they source the parts.
