ABSTRACT:
A ball joint assembly with a preload feature derived from a dished washer type compression spring located between the semi-spherical head of the stud unit and the ball joint housing. The inner diameter edge of the dished washer spring engages the stud unit and has radially outward extending slotted portions therein which effectively shift the area of greatest flexure and stress outward from the inner edge on which the greatest wear occurs.
