A differential pinion bearing supports the pinion shaft in the carrier. It carries the loads created where the pinion meshes with the ring gear. Signs this part may need replacing include a whine or howl from the differential that changes between acceleration and coasting, a rumbling noise, or play at the pinion. Worn gears and other bearings can make similar noises, so diagnose the cause before replacing parts.
