Abstract: A fixture for press fitting an end yoke onto the end of a vehicle drive shaft tube includes a base having a plurality of tube supports secured thereto for supporting the tube thereon in a predetermined axial orientation. An end fitting is supported on a vertically-oriented, support pin assembly. The support pin assembly includes an upstanding pin having slot formed through the center of the upper end thereof. The slot has a lower edge which extends at an angle relative to the pin. A tab is retained within the slot and guided for sliding movement between a first extended position and a second retracted position. In the extended position, the tab defines a first width for the support pin assembly. In the retracted position, the tab defines a second width for the support pin assembly which is less than the first width.
