ABSTRACT:
A universal joint assembly includes a cross having a plurality of trunnions extending outwardly therefrom. An internal passageway is formed in each of the trunnions that extends through to the outer end thereof. A bearing cup is disposed about each of the trunnions, and a plurality of needle bearings is disposed between each of the bearing cups and its associated trunnion to facilitate relative rotational movement. A thrust washer is disposed between the outer end surface of each of the trunnions and its associated bearing cup. Each of the trust washers is generally annular in shape, including an outer flat portion and an inner frusto-conical portion having a central opening formed therethrough. One or more grooves may be formed in one or both sides of the thrust washer. The frusto-conical portion of the thrust washer extends within the lubricant passageway to facilitate the installation thereof in a centered position on the outer end of the trunnion and subsequently maintain the thrust washer in that desired position during use.
