Abstract
An axle shaft retention structure includes a retainer ring trapped between a shoulder on an axle shaft and the inner end of a hollow sleeve which is a part of a universal joint. The hollow sleeve is attached to the axle shaft by a snap ring. The retaining ring is provided with spherical slots which receive the spherical inner ends of retaining screws extending through the axle housing. The retaining screws nest into the spherical slots in the retaining ring inward against an internal shoulder on an axle housing. The shoulder on the axle housing and retaining screws limit both axial and rotary movement of the retainer ring. Thus, end play, which is detrimental to oil seal life, is limited to a minimum.
