H233 Differential Large Pinion Bearing - Nissan Patrol GQ & GU This large pinion bearing is located within the front or rear H233 differential housing, supporting the pinion gear shaft. It is a crucial component that allows the pinion gear to spin smoothly and maintain correct alignment with the crown wheel gear. Over time, differential bearings are subjected to immense pressure and heat, causing them to wear out. This can lead to a whining or humming noise from the differential, which often changes pitch with vehicle speed. Replacement is essential during a differential rebuild, gear ratio change, or when addressing bearing noise to restore quiet and reliable operation. Ignoring a failing pinion bearing can lead to catastrophic differential failure. The initial whine can escalate into a loud grinding noise as the bearing deteriorates. Eventually, the bearing can collapse, causing the pinion gear to move out of alignment and destroy the crown wheel and pinion gear set. In a worst-case scenario, this can cause the differential to lock up, leading to a loss of vehicle control.
