Detailed Description

The InMotion WS710126 is a differential pinion seal engineered around precise dimensions: 45.6 mm inside diameter, 69.4 mm housing bore, 69.6 mm outside diameter, and 11 mm width. Those measurements matter when replacing a worn seal on the differential pinion, where a stable fit helps reduce gear oil leakage and limits contamination at the internal components. For drivers servicing a Nissan 300ZX front inner application, WS710126 provides a direct replacement path based on the listed fitment.

This seal is built from nitrile, with a SAE 1070 seal case and SAE 1008 spring material to maintain sealing contact under operating conditions. The result is a practical replacement for vehicles that need a reliable barrier against debris and moisture in the driveline. WS710126 is a focused solution for Nissan 300ZX differential service, especially when the original seal shows wear, seepage, or contamination-related damage.

What It Helps Address

• Gear oil seepage at the differential pinion area
• Contamination from dirt, water, and road debris
• Loss of sealing tension from an aged or hardened seal
• Wear-related leakage during differential service
• Seal replacement needs on 1987-1989 Nissan 300ZX front inner applications

Installation Notes and Tips

Confirm housing bore, shaft diameter, and seal orientation before installation. Clean the sealing surface thoroughly and inspect the pinion area for scoring or wear that could affect the new seal. Proper seating depth is important for maintaining a uniform seal, and the mating surface should be free of burrs or contamination. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
