  • Driveline yoke with improved seal retainer
    Patent number: 5078533
    Abstract: A seal is held against the end of the sleeve of a driveline yoke by a retainer formed with angularly spaced windows having axially facing edges which snap past and lock behind angularly spaced lugs on the sleeve when the retainer is telescoped onto the sleeve. Release of the retainer is effected by twisting the retainer to cause circumferentially facing side edges of the windows to cam against sloped side surfaces of the lugs and deflect the axially facing edges of the windows outwardly from behind the lugs so as to permit the retainer to be slipped axially off of the sleeve.
