Abstract
A joint housing has mounted therein a bearing supporting a ball portion of a ball stud, extending outwardly therefrom, so as to allow angular displacement thereof. The ball portion comprises a greater diameter portion of the ball stud, such as a sphere-segmental head on its extreme end, and a sphere-segmental shell coaxially surrounding the ball stud with a spacing therebetween. The shell has an inturned annular rim at one end thereof in an opposed relation to an annular shoulder provided by the head of the ball stud. A one-piece elastomeric bushing is injection molded in place between the ball stud and the shell. Part of the bushing further fills the annular gap between the shoulder of the ball stud and the inturned rim of the shell. Preferably prestressed, this part of the bushing serves to prevent the development of looseness with the progress of wear and further to minimize the axial displacement of the ball stud relative to the joint housing under load.
