Abstract

A trunnion of a universal joint cross-shaped member supports a bearing cup, thrust washer, and needle bearing assembly. The thrust washer includes a first surface that faces the bearing cup and a second surface that faces an end face of the trunnion. A first lip extends outwardly from the first surface to contact the bearing cup and a second lip extends outwardly from the second surface to contact the needle bearing assembly. The first and second lips cooperate to hold the bearing cup and needle bearing assembly in a proper installation for final assembly to form a universal joint assembly.
