AEU2515 Rear Differential Pinion Oil Seal – Defender & Series

Stop rear differential leaks at the pinion flange with this Rear Differential Oil Pinion Seal (Part No. AEU2515). This seal prevents gear oil from escaping where the driveshaft connects to the rear differential—an area that commonly wears with age, causing drips, low gear oil levels, and potential differential damage if left unchecked.

This replacement seal restores a tight, reliable fit and is essential during driveline service or after removing the driveshaft/pinion flange.

Install tip: Replace the pinion nut and mark the flange position before removal to maintain proper preload on the differential.*
