Detailed Description

National 710986 is an oil seal designed for rear differential sealing where the shaft measures 1.496 inches (38.000 mm) and the housing bore measures 2.154 inches (54.700 mm). The seal’s ethylene-acrylic construction supports sealing performance in driveline and axle service, while the metric sizing helps match the original application requirements. This part cross-references SKF 14473A for the same application. It is a direct-fit style service part for vehicles including Nissan Murano, Nissan Rogue, Nissan X-Trail, and INFINITI QX60 with the Nissan R145 differential.

What It Helps Address

• Rear differential oil leakage at the axle seal area
• Fluid seepage around the differential housing bore
• Seal wear from age, heat, and driveline use
• Loss of differential fluid caused by a damaged sealing lip
• Service replacement needs on Nissan R145 differential applications

Installation Notes and Tips

Verify shaft diameter, housing bore, and overall seal dimensions before installation. Clean the sealing surface and inspect the axle shaft and differential bore for wear, scoring, or contamination that could affect sealing. Confirm rear-position fitment and differential type before ordering. Fits 2014-2019 INFINITI QX60, rear, with Nissan_R145 Differential.
