Abstract
An annular two-piece thrust washer for use between the end wall of a bearing cup and the axially outer ends of the bearings and trunnion of a universal joint assembly includes a first piece and a second piece. The first piece is sized to be disposed between the axially outer ends of the bearings and the end wall of the bearing cup. In a preferred embodiment, a circumferential recess is formed at the junction between the radially inner surface and the axially outer surface of the first piece. The second piece of the thrust washer is sized to be disposed between the trunnion and the end wall of the bearing cup. When assembled, the second piece of the thrust washer is disposed within the first piece. The outer circumferential portion of the second piece extends into the circumferential recess of the first piece. A predetermined small clearance is provided between the first piece and the second piece which allows a limited amount of relative movement therebetween.
