Abstract
Abstract A ball joint link includes a center tube and a ball stud. A one-piece, thermoplastic, molded housing extends around the ball to form a ball joint and is secured to the tube. The tube and the ball of the ball stud are both insert molded in the housing in a single molding operation, and the housing is formed of a glass-filled nylon that forms the bearing surface for the ball joint.
