InMotion Differential Pinion Seal WS710839

The InMotion WS710839 differential pinion seal is built to maintain a secure barrier at the pinion area, helping keep contaminants out and gear oil in. It is a direct-fit sealing component for select Jeep Commander and Jeep Grand Cherokee applications with Chrysler C200F and C200FE differentials.

Key Features

• Fluoro-elastomer construction for sealing performance in driveline service
• Inside diameter: 1.575 in.
• Outside diameter: 2.843 in.
• Housing bore: 2.835 in.
• Thickness: 0.394 in.
• Shaft diameter: 1.575 in.
• Fits front outer differential pinion locations on select Jeep Commander and Jeep Grand Cherokee models

Detailed Description

Built for driveline sealing demands, the WS710839 differential pinion seal is engineered around precise dimensions to support a tight fit at the pinion opening. The fluoro-elastomer material is selected for resistance in sealing applications where heat, fluid exposure, and contamination control matter. For Jeep Commander and Jeep Grand Cherokee vehicles equipped with Chrysler C200F or C200FE differentials, this seal helps maintain the integrity of the differential assembly and supports consistent lubrication retention.

This part number, WS710839, is a practical choice when servicing the front outer pinion seal on the listed Jeep applications. It cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Differential gear oil seepage at the pinion seal area
• Contamination entering the differential housing
• Wear related to degraded sealing surfaces
• Loss of lubrication that can affect differential operation
• Service needs on Jeep Commander and Jeep Grand Cherokee front outer pinion locations

Installation Notes and Tips

Confirm differential type before ordering: this seal is listed for Chrysler C200F and C200FE differential applications only. Inspect the pinion shaft and housing bore for wear, scoring, or corrosion before installation, and verify the seal dimensions against the original part. Proper seating and clean mating surfaces are important for a reliable seal. The WS710839 should be installed only on the confirmed front outer application shown in the fitment data.
