The ball joint position is indexed and relocated to correct for alignment and range of motion for 1"-4" of lift. When used with 1" of lift, caster will be at the high end of the specification; Do NOT hit the aluminum knuckle with a hammer to separate the ball joint. Use appropriate ball joint separation tool (OTC 204-592); A ball joint press is needed to press out the ball joint in the factory arm and press it into the Zone Offroad UCA. ATD 8696 ball joint press is recommended and can be rented from most auto parts stores.
