Signs a pinion bearing may need replacing include a whine or growl from the differential that changes on acceleration or deceleration, and noticeable play at the pinion yoke. Worn gears or other bearings can make similar noises, so diagnose the cause before replacing anything. If a worn pinion bearing is the cause, this National bearing replaces it. Installation typically involves setting bearing preload and checking the gear setup, so follow the vehicle service information.
