    Rear Differential Pinion Oil Seal ️

    This OEM-grade pinion oil seal keeps gear oil inside the final drive and dirt out. On Nissan luxury RWD platforms, it sits around the pinion flange where the driveshaft meets the differential. By locking in lubricant, it protects bearings and the ring & pinion, keeps noise low, and prevents messy leaks.

    Why you need it ⚙️

    Without a tight seal, gear oil level drops, heat rises, and metal parts scuff. A fresh rear differential oil seal maintains correct lubrication, prevents corrosion, and extends service life—saving you from costly rebuilds and roadside breakdowns.

    How it works

    A spring-loaded elastomer lip hugs the yoke surface while a rigid outer shell press-fits into the housing. As the shaft turns, the lip maintains even contact, channeling oil back in and blocking splash, dust, and water. The design handles heat, vibration, and shaft runout for long, quiet operation.

    If it fails

    Watch for wetness at the pinion nut, gear oil spots under the rear, humming/whine on acceleration, and burnt-oil smell. Continued driving can starve bearings, score the ring & pinion, overheat the diff, and even damage the driveshaft joint.
