Zusammenfassung:	An improved ball joint assembly includes a ball stud having a head end portion which is at least partially enclosed by a housing. A contact member has an end portion which engages the head end portion of the ball stud prior to the occurrence of a predetermined amount of wear in the ball joint assembly. The contact member and head end portion of the ball stud are spaced apart upon the occurrence of the predetermined amount of wear in the ball joint assembly. Prior to the occurrence of the predetermined amount of wear in the ball joint assembly, an electrical circuit through the contact member and head end portion of the ball stud is closed. Upon the occurrence of the predetermined amount of wear in the ball joint assembly, the electrical circuit is opened.
