It slides onto the spindle between the inner wheel bearing and the adjusting nut, with a keyway tab that locks it in place. It prevents the axle nut from loosening due to vibration and road shock. Replace it whenever wheel bearings are serviced, brakes are done, or if the washer is worn, bent, or missing, which can cause bearing play and wheel-end damage.
