Detailed Product Overview

This differential pinion seal is designed for rear driveline service where the pinion shaft passes through the axle housing. Its sealing design helps retain lubricant at the pinion area while limiting entry of dirt, dust, and moisture. The listed dimensions and seal construction make it a direct-fit service part for many rear axle applications across the Nissan and INFINITI lineup, including the 2003-2009 Nissan 350Z, 2008-2013 INFINITI G37, 2005-2012 Nissan Pathfinder, and 2014-2018 INFINITI Q70.

Use FAG SS4457 when servicing rear differential leaks or replacing a worn pinion seal on vehicles such as the Nissan Frontier, INFINITI QX50, and INFINITI QX70. The part number SS4457 is also useful when searching by interchange or OE-style reference during axle repair.

Common Problems This Seal Can Address

• Rear differential oil seepage at the pinion shaft
• Contamination entering the axle housing through a worn seal
• Loss of gear lubricant from the pinion area
• Noise or wear caused by low differential fluid level
• Service replacement for aged or hardened axle seals

Installation Notes and Tips

Confirm axle and vehicle application before installation, since fitment varies by model, year, and rear axle configuration. Inspect the pinion yoke, shaft surface, and housing bore for wear or damage before pressing in the new seal. Clean the sealing surface thoroughly and verify the seal is seated squarely to help prevent leaks after service.
