Abstract
The ball joint assembly includes a housing with an inner wall which surrounds an inner bore that extends along a central axis. The ball joint assembly further includes a ball stud with a ball portion and a shank portion. The ball portion is received in the inner bore of the housing, and the shank portion projects out of the inner bore through an open end of the housing. First and second preload members are disposed in the inner bore on opposite axial sides of the ball portion and are in contact with the ball portion. The preload members are of an elastomeric material. At least one of the preload members is compressed to urge the ball portion to a central location.
