InMotion WS6815 Wheel Seal - Front Inner or Rear Inner

Wheel Seal for Differential Pinion Applications

The InMotion WS6815 wheel seal is built with nitrile sealing material and a spring made from SAE 1008 steel to help maintain a secure barrier at the differential pinion area. With precise dimensions and a compact 0.25-inch width, it is suited for front inner and rear inner applications across a wide range of Ford, Jeep, Lincoln, Mercury, Mazda, and Dodge vehicles.

Use this seal when you need a direct-fit replacement for a leaking or worn differential pinion seal on vehicles such as the Ford Mustang, Jeep Cherokee, or Ford Ranger. The WS6815 is sized for a 1.89-inch inside diameter, 2.50-inch housing bore, and 2.51-inch outside diameter for accurate sealing performance.

Detailed Description

InMotion WS6815 is a precision-engineered seal for differential pinion service, made to help block contaminants such as dirt and moisture while retaining lubricant inside the assembly. Its nitrile construction supports reliable sealing in driveline environments, and the spring-loaded design helps maintain contact under operating conditions. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Compatible With 1955-1997 Ford Mustang, front inner; 1983-1994 Ford Ranger, front inner; and 1986-1993 Jeep Cherokee, front inner. It also serves many other applications across Ford, Mercury, Lincoln, Mazda, Jeep, and Dodge platforms listed in the fitment data.

Common Problems This Seal Can Address

• Differential pinion oil leakage
• Contamination from road debris and moisture
• Worn or hardened original seal material
• Loss of sealing tension at the pinion area
• Service replacement during driveline maintenance

Installation Notes and Tips

Verify shaft diameter, housing bore, and seal width before installation. Clean the sealing surface thoroughly, inspect the pinion yoke or shaft for wear, and install the seal squarely to avoid distortion. Confirm the application position before ordering, since this part is listed for both front inner and rear inner locations depending on vehicle.
