Abstract:
A method of assembling a joint, said method comprising the steps of:providing a metal housing having an end wall and a side wall which defines an opening to a chamber in the housing;placing a coil spring in the chamber in the housing, the coil spring engaging the end wall of the housing;inserting a first bearing formed of a polymeric material into the chamber in the housing, the first bearing engaging and compressing the coil spring and being urged in an axial direction away from the end wall of the housing by the bias of the coil spring;providing a movable member having a head end portion in the chamber in the housing and a shank portion extending from the head end portion, the head end portion engaging the first bearing in the chamber and being urged in the axial direction away from the end wall of the housing by the bias of the coil spring acting on the first bearing, the shank portion being at least partially disposed outside of the chamber in the housing;inserting a second bearing formed of metal in the chamber into the housing and into engagement with the head end portion of the movable member, the second bearing being urged in the axial direction away from the end wall of the housing by the bias of the coil spring acting on the first bearing;retaining the second bearing and the head end portion of the movable member in the chamber against movement relative to the housing due to the bias of the coil spring by an interference fit between a cylindrical outer side surface of the second bearing and a cylindrical inner side surface of the housing, the interference fit being sufficient to hold the coil spring in a compressed condition against the bias of the coil spring; andthereafter, deforming a rim portion of the housing surrounding the opening radially inward into engagement with the second bearing to form an annular lip which overlies the second bearing and assists the interference fit in retaining the second bearing in the housing.
