A ball-and-socket joint, preferably for vehicle suspensions or steering mechanisms of motor vehicles, with a joint housing and a pivot pin, which is mounted rotatably and deflectably in a spherical bearing surface by means of a one-part or multipart bearing shell, wherein the bearing shell itself is fixed in the joint housing and wherein the joint housing or the pivot pin is fixed against the vehicle suspension in an electrically insulated manner, in which the joint housing 1 and the pivot pin 2 are connected according to the present invention to a potential difference-measuring means 13 by means of electrical contacting 12, 14 and the spherical bearing surface of the pivot pin 2 and its corresponding opposite surface in the joint housing 1 are electrically insulated against each other. Due to this measure according to the present invention, the state of wear of a ball-and-socket joint can be determined and the user of the motor vehicle can obtain an indication of the end of the service life of the ball-and-socket joint and the necessary repair in time.
