Detailed Product Overview

This differential pinion seal is designed to create a secure barrier at the rear differential pinion, helping protect sensitive internal components from moisture and debris. The precision dimensions support a proper seal at the shaft and housing interface, which is important for maintaining differential fluid retention and reducing wear-related contamination. InMotion WS710363 is a practical replacement for rear differential service on Nissan and INFINITI platforms such as the 2003-2006 Nissan 350Z, 2002-2006 Nissan Altima, and 2003-2006 INFINITI G35.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Seal Can Address

• Differential fluid seepage at the pinion area
• Contamination entering the rear differential housing
• Seal wear from age, heat, and road exposure
• Noise or drivability concerns linked to low differential fluid level
• Service replacement during rear differential maintenance

Installation Notes and Tips

Verify shaft diameter, housing bore, and rear position before installation. Clean the sealing surface thoroughly and inspect the pinion area for wear, scoring, or contamination that could affect seal performance. Proper installation technique and correct differential fluid level are important for long-term sealing results.

Quality Assurance

InMotion manufactures this seal with precision-focused construction and fluoro-elastomer material selection to support reliable sealing in rear differential service.
