Abstract
A combination of a thrust washer and lubrication baffle adapted for a press fitting installation into lubrication chamber of a universal joint cross-member journal. The thrust washer and lubrication baffle incorporate one or more lubrication grooves, facilitating the flow of lubricant between the surfaces of the cross-member and bearing cap. Elastomeric properties of the thrust washer eliminate the need for grinding of the journal surfaces to desired tolerances, while incorporation of lubrication grooves into the thrust washer surface eliminates the need for pressing of lubrication grooves directly into the journal ends prior to hardening or heat treating.
