Abstract
A ball joint has a metallic ball stud shaft with a ball at one end that fits within a housing that defines a ball socket. A primary liner made of a non-metallic material surrounds the housing inside surface. The ball is separately encased in a secondary liner that acts as a seal to prevent moisture and debris from collectively corroding and marring the outside surface of the metallic ball and the primary liner. The primary and secondary liners rotate against each other and create a corrosion-free articulation surface. A dust seal part seals with the ball joint housing and the ball stud shaft. A recess in the ball accepts a tab formed on the secondary liner to prevent the secondary liner from rotating on the ball during ball articulation. Lubrication channels may be formed in the primary liner to lubricate the articulation surfaces of the liners.
