ABSTRACT:
A ball joint (10) comprises a socket (60), a bearing (100), and a stud (80). The bearing (100) supports a first end portion (82) of the stud (80) in the socket (60) for movement relative to the socket. The stud (80) has a second end portion (84, 86) projecting from the socket (60) for connecting the stud for movement with the first suspension member (14). The socket (60) has a mounting portion (64) for connecting the socket for movement with the second suspension member (40) relative to the stud (80) and the first suspension member (14). The bearing (100) includes first and second relatively movable bearing elements (110, 130). The first bearing element (110) is movable with the first end portion (82) of the stud (80) in the socket (66), and has a pivot center (118). The second bearing element (130) is disposed between the first bearing element (110) and the socket (60), and supports the first bearing element and the stud (80) for pivotal movement relative to the socket about the pivot center (118). A biasing spring (150) acting between the socket (60) and the second bearing element (130) yieldably resists movement of the first and second bearing elements (110, 130) relative to the socket.
