ABSTRACT:
A journal cross includes a trunnion having a lubricant passageways formed therethrough. A retainer is disposed in the lubricant passageway and includes a body portion and a lip portion. The body portion of the retainer is retained within the lubricant passageway in a press fit relationship, and the lip portion of the retainer extends inwardly into the lubricant passageway. The bearing cup includes a thrust washer that is retained therein by needle bearings and a seal assembly. The thrust washer includes a projection that extends radially inwardly within the lubricant passageway and has one or more fingers provided thereon. When the bearing cup is installed on the trunnion, the fingers of the thrust washer cooperate with the lip portion of the retainer to retain the bearing cup on the trunnion, such as during shipment from one manufacturing location to another.
