ABSTRACT An injection molded universal joint (10) in- cludes a central retaining member (40) captured between spherical balls (30, 32, 34, 36) seated in bores (22, 24, and 26, 28) located in diametrically opposed arms (14, 16, and 18, 20) of respective shaft members (11, 12). The spherical balls are each pressed through an associ- ated bore until a portion of the ball extends radially inwardly of the arm, and then maintained in position by a plastic material (80) insert molded into and retained in the bore. The insert molded plastic material (80) re- tains each of the spherical balls in place and permits the central retaining member (40) to be accurately posi- tioned and with a predetermined preload applied to the universal joint (10).
