Wheel Seal for Classic Dodge and Fargo Applications

InMotion WS6781 is a wheel seal built for front inner applications on a wide range of classic Dodge and Fargo trucks and vans. It uses a leather sealing material and precise dimensions to help keep contaminants out and lubricant in.

Key Features

  • Leather seal material for a traditional sealing design
  • Precision sizing with a 1.796 inside diameter and 2.73 outside diameter
  • 0.5 width for a compact seal profile
  • Matches applications with a 2.725 housing bore and 1.796 shaft diameter
  • Fits front inner positions on multiple Dodge and Fargo models

Detailed Description

The InMotion WS6781 is a differential pinion seal designed to create a secure barrier against debris and moisture at the differential assembly. Its leather construction and exact dimensional fit support reliable sealing performance where contamination and fluid loss can shorten component life. This part number, WS6781, is listed for numerous vintage Dodge and Fargo applications, including Dodge D100 Pickup, Dodge D200 Pickup, and Fargo P200 Parcel Delivery models. The WS6781 is also cataloged for additional Dodge and Fargo truck and van platforms with notes for brake and axle variations, making fitment review important before ordering.

What It Is Used For

  • Stopping gear oil leaks at the differential pinion area
  • Blocking dirt and moisture from entering the seal interface
  • Replacing worn or hardened sealing surfaces
  • Restoring proper sealing on aging driveline assemblies
  • Addressing seepage that can lead to low lubricant levels

Installation Notes and Tips

Confirm the vehicle year, make, model, and front inner application before installation. Review brake and axle notes carefully, including listings that specify 12 in x 2.5 in brakes or exceptions for heavy duty axles. Measure the housing bore and shaft diameter to verify the seal dimensions match the application. Professional installation is recommended for driveline sealing service.

Quality Assurance

InMotion manufactures this seal with precision and high-quality materials to support dependable sealing performance in differential service.
