Timken 712020 Differential Pinion Seal - Front or Rear

Timken 712020 Differential Pinion Seal

The Timken 712020 differential pinion seal is a front axle sealing component for select Nissan and INFINITI applications. It is built to retain gear oil at the pinion area while helping block dirt and other contaminants from entering the driveline.

Key Features

• Precision sealing design helps control lubricant loss at the differential pinion
• Reinforced outer case helps resist installation damage and improve durability
• Ribbed rubber inner diameter helps seal minor spindle imperfections and promote seating
• Internal contamination exclusion system helps reduce debris intrusion that can lead to leakage
• Vent holes allow lubricant flow around the seal lip to help manage heat build-up

Detailed Description

Timken 712020 is a differential pinion seal for front applications on vehicles such as the Nissan Frontier, Nissan Pathfinder, Nissan Xterra, Nissan Armada, Nissan GT-R, and select INFINITI models. It is designed to maintain a tight seal at the pinion area, where gear oil retention is critical for differential operation and long-term driveline protection. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Gear oil seepage at the differential pinion seal area
• Contamination entering the differential through a worn seal
• Heat-related seal wear from poor lubricant circulation
• Leakage caused by minor surface imperfections at the sealing interface
• Noise or driveline wear associated with low differential lubricant level

Installation Notes and Tips

Inspect the pinion yoke, sealing surface, and surrounding housing before installation. Clean the bore thoroughly and verify the replacement seal matches the front or rear application listed for your vehicle. For best results, install the seal squarely to avoid lip damage and confirm proper seating before refilling the differential.
