The ball joint assembly (20) includes a housing (26) with an inner wall (40) that surrounds an axially extending open bore. A ball portion (48) of a ball stud is received in the open bore of the housing, and a shank portion (50) of the ball stud projects out of the open bore. A pair of bearings (56, 58) are disposed in the inner bore of the housing and are interposed between the ball portion and the inner wall. Each bearing has a curved bearing surface (60, 62) which slidably contacts the ball portion for allowing the ball stud and the housing articulate relative before use. Each bearing also has an outer surface (64, 66) that slidably contacts the inner wall. A pair of biasing elements (70, 72) bias the bearings in opposite directions against the ball portion of the ball stud such that the ball stud is movable relative to the housing in the axial direction before use of the assembly.
