Claim:
A hub member and shaft journal assembly comprising: an inner joint part of a constant velocity universal ball joint in the form of a hub member ( 11 ) which comprises a central through-aperture ( 14 ) with an inner toothing ( 16 ) for receiving a shaft journal ( 12 ), and ball tracks ( 15 ) for receiving torque-transmitting balls on an outer circumference, wherein the inner toothing ( 16 ) is formed in a predetermined limited length as far as a toothing run-out ( 17 ) inside the through-aperture and is followed by a bore ( 18 ) with a reduced diameter; and a shaft journal ( 12 ) having shaft toothing ( 19 ) introduced into the inner joint part, the shaft journal ( 12 ) having, at a distance from a shaft end, a first conical step ( 22 ) which serves as a stop face relative to the toothing run-out ( 17 ) of the inner toothing ( 16 ) at the inner joint part and directly contacting said toothing run-out ( 17 ), and a larger second conical step ( 21 ), which is positioned at an axial distance from the first conical step ( 22 ) and which forms a toothing end of the shaft toothing ( 19 ).
