InMotion WS484054 Wheel Seal - Rear

Rear Differential Pinion Seal for Ford and Mercury

The InMotion WS484054 is a rear differential pinion seal built with nitrile material for dependable sealing at the pinion shaft. It helps keep gear oil contained while blocking moisture and road debris from entering the differential housing.

Compatible With 1962-1966 rear applications, including Ford Mustang and Mercury Villager, this seal is sized for a 1.326 in inside diameter, 2.065 in outside diameter, and 0.375 in width. The WS484054 is a direct-fit sealing component for service work on the differential pinion area.

Key Features

• Nitrile construction for sealing performance in driveline service
• 1.326 in inside diameter and shaft diameter
• 2.065 in outside diameter for housing fitment
• 0.375 in width for compact differential sealing applications
• Designed for rear differential pinion use
• InMotion WS484054 part number for catalog matching

Detailed Description

InMotion WS484054 is a wheel seal listed for rear differential pinion service, engineered to create a secure barrier between internal differential components and outside contaminants. The nitrile sealing material is selected for its ability to maintain contact at the shaft and housing interface, helping reduce fluid loss and protect the pinion area from debris and moisture. This makes the WS484054 a practical choice for maintenance on older Ford and Mercury driveline assemblies, including 1964-1966 Ford Mustang rear applications and 1962-1965 Mercury Villager rear applications. If you are searching for a rear differential pinion seal for Ford Mustang or Mercury Villager, WS484054 provides the dimensional match needed for service replacement.

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

What It Helps Address

• Gear oil seepage at the differential pinion seal area
• Contamination from dirt, water, and road debris
• Wear-related sealing loss around the pinion shaft
• Service replacement needs on rear differential assemblies
• Fitment searches for Ford Mustang rear pinion seal and Mercury Villager rear pinion seal

Installation Notes and Tips

Confirm housing bore, shaft diameter, and seal width before installation. Clean the seal bore and pinion surface thoroughly, and inspect the mating surfaces for scoring or wear that could affect sealing. Proper alignment during installation is important to avoid damaging the nitrile lip and to maintain a consistent seal at the differential pinion.

Quality Assurance

InMotion manufactures this seal with precision-focused dimensions and high-quality materials for driveline sealing service. The WS484054 is built to support reliable containment of differential lubricant and consistent fitment in the listed rear applications.
