A universal joint yoke has a ball and socket connection at one end. The ball is held in the socket with an assembly of a retainer and a hidden spring. The spring is rectangular and is compressed into an external rectangular groove of the retainer. The retainer is then inserted into a recess at the end of the socket. The retainer must be inserted past its final farthest-in position for the spring to expand into an internal rounded groove in the recess to assure a loose connection without any preload on the ball. |
