ABSTRACT:
A ball joint (10) for interconnection between relatively movable parts (12, 14/16) includes a ball stud (70) having a central ball portion (24) and a pair of stud portions (40, 42) extending in diametrically opposite directions from the central ball portion. The stud portions (40, 42) and the central ball portion (24) have a central passage (54) extending axially through the stud portions and the central ball portion. A fastener (260) extends through the central passage (54) for attaching the ball stud (20) to the movable parts (12, 14/16). A housing (60) encloses the central ball portion (24) and has opposite openings (74, 88) through which the respective stud portions (40, 42) extend. First and second bearings (100 and 130) for the central ball portion (24) support the central ball portion in the housing (60) for movement relative to the housing. First and second seals (170 and 200) close the opposite openings (74, 88) in the housing (60). The first and second seals (170 and 200) have first sealing surfaces (186, 216) engaging the housing (60) around the respective opposite openings (74, 88) and second sealing surfaces (178 and 208) engaging the respective stud portions (40, 42) around the stud portions.
