Differential Washer

A car differential is a gearbox that is used to transmit power from the engine to the gears that move the car’s wheels. The differential also allows the wheels of the car to move at different speeds during a turn. A differential comprises a housing having a spider mounted therein and four pinion gears rotatably mounted on stub shafts of the spider in a conventional manner. A semi-spherically shaped thrust washer is disposed between an outboard side of each of the pinion gears and the housing and has an elongated slot formed therethrough and disposed entirely within the confines of the thrust washer.
