ABSTRACT:
A resilient compression member for a ball joint which has a wear indicating mechanism formed integrally therewith is disclosed. The compression member preloads a ball unit of the joint within a socket-like housing. The compression member includes an indicator pin formed integrally therewith. The indicator pin is disposed within an annular recess extending partially through the body of the compression member. The indicator pin is attached to the body of the compression member by means of a relatively thin membrane-like web portion. The end of the indicator pin extends outwardly from the compression member recess and the housing of the joint by a predetermined distance. As wear occurs within the joint, the exposed end of the indicator pin is moved relative to the housing of the joint. Accordingly, a visual indication of the amount of wear within the joint is provided from outside the joint.
