ABSTRACT:
A ball joint includes a socket defining a chamber and having an opening therein. A ball stud has a ball portion in the chamber and a shank portion projecting through the opening. A bearing supports the ball portion in the chamber. A seal member seals the opening between the socket and the ball stud. The seal member includes a shank seal portion for sealing against the ball stud shank, a retaining ring, and a socket seal portion for sealing against the socket. The retaining ring is molded in the socket seal portion of the seal member. The socket seal portion with the retaining ring molded therein is located in the chamber. An axial end portion of the socket holds the socket seal portion in position against the bearing and the inner surface of the socket. The retaining ring blocks movement of the ball portion out of the chamber through the opening.
