Front Inner Differential Pinion Seal

The InMotion WS444116 is a nitrile wheel seal built to create a secure barrier at the differential pinion area. It helps keep moisture and road debris out while supporting a tight seal that reduces fluid loss and internal wear.

Compatible With 1982-1984 Nissan Maxima, front inner; 1984-1986 Nissan 200SX, front inner; and 1984-1986 Nissan 300ZX, front inner. The WS444116 is a direct-fit sealing component for vehicles that need precise pinion-side protection.

Key Features

  • Nitrile construction for sealing performance and resistance to contaminants
  • Inside diameter: 1.812 in.
  • Outside diameter: 2.332 in.
  • Width: 0.437 in.
  • Shaft diameter: 1.812 in.
  • Housing bore: 2.327 in.
  • Designed for the front inner differential pinion seal location

Detailed Description

InMotion WS444116 is engineered around the dimensions required for a precise seal at the differential pinion. By maintaining a tight interface between the shaft and housing bore, it helps protect sensitive internal components from debris and moisture while supporting stable differential operation. This seal is a practical choice for Nissan 200SX, Nissan 300ZX, and Nissan Maxima applications that call for a front inner seal with these specifications.

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

Common Issues Addressed

  • Differential fluid seepage at the pinion seal area
  • Contamination from water, dirt, and road debris
  • Wear caused by a compromised sealing surface
  • Noisy or inconsistent differential operation related to seal failure
  • Loss of protection for internal differential components

Installation Notes and Tips

Confirm the shaft diameter, housing bore, and seal width before installation. Clean the sealing surfaces thoroughly and inspect the pinion area for scoring or wear that could affect seal life. Verify front inner placement and match the vehicle application to the listed fitment before assembly.

Quality Assurance

InMotion manufactures this seal with precision-focused dimensions and high-quality nitrile material to support reliable sealing performance in differential service.
