My maintenance manual says the ball joint and swing arm are and integral part and you have to buy the arm and joint together as one piece. But my local AutoZone has the ball joint available with some loaner tools to push the joint out of the arm. Is my manual wrong? I sure hope so because I’d hate to have to remove perfectly good swing arm.
