InMotion WS100715V Differential Pinion Seal - Rear Outer

Overview

InMotion WS100715V is a differential pinion seal built to keep contaminants out and lubricant in at the pinion area. It uses fluoro-elastomer construction for sealing performance across a wide range of rear outer applications, including Ford E-350 Super Duty, Ford E-450 Super Duty, and Dodge Viper fitments.

Key Features

• Fluoro-elastomer material for resistance to heat and sealing wear.
• Precision dimensions: 1.874 in. inside diameter, 3.163 in. outside diameter, and 0.5 in. thickness.
• Designed to maintain a tight barrier against moisture and debris.
• Fits rear outer differential pinion applications with Spicer axle and independent carrier configurations.
• Part number WS100715V for direct catalog identification.

Detailed Description

This differential pinion seal is engineered for applications that require a secure seal at the pinion shaft and housing bore interface. The fluoro-elastomer construction supports consistent sealing where exposure to gear oil, road contamination, and moisture can accelerate wear. Fitment includes rear outer applications for Ford E-250, Ford E-350 Super Duty, Ford E-450 Super Duty, Ford E-550 Super Duty, Dodge Ram 1500, Dodge Ram 2500, Dodge Ram 3500 Van, Chevrolet Express 2500, Chevrolet Express 3500, GMC Savana 2500, GMC Savana 3500, and Dodge Viper models listed for this part number WS100715V.

For buyers searching for a rear outer differential pinion seal for Ford E-350 Super Duty or a differential pinion seal for Dodge Viper rear outer applications, WS100715V provides a fitment-specific sealing solution. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Gear oil seepage at the pinion seal area.
• Contamination entering the differential housing.
• Seal wear from moisture and debris exposure.
• Loss of sealing integrity at the pinion shaft interface.
• Service needs on rear outer differential applications.

Installation Notes and Quality

Verify axle configuration, carrier type, and housing bore dimensions before installation. Confirm the application notes for Spicer 70-2U, Spicer 60-1, Spicer 60, or independent carrier assemblies where listed. Proper sealing surface condition is important for reliable performance. InMotion identifies this seal as a precision-engineered component made from high-quality materials for differential sealing applications.
