  • Patent number: 4869556
    Abstract: A constant velocity universal joint of an axle shaft assembly has a drive hub which receives a splined shaft in an extension which projects from a drive bell. The splined shaft is held in the drive hub in such a position that it can be pushed further into the drive hub after removal of a locking ring. This makes it possible to shorten the axle shaft assembly for the purpose of mounting by an additional amount in comparison to prior-art axle shaft assemblies.
