Abstract

A thrust washer of a planetary gear of a differential assembly has an anti-rotation feature. In one embodiment washer (21) has flats (24). In another embodiment a washer (31) has protruding ribs (34). In each case the anti-rotation feature engages an abutment provided by a differential casing. The washers (21,31) are preferably sintered and have different profiles on the opposite faces thereof.
