InMotion WS7600S Wheel Seal - Front Inner

Wheel Seal for Differential Pinion Service

InMotion WS7600S is a nitrile wheel seal built for differential pinion sealing applications where contamination control and leak resistance matter. It helps maintain a tight barrier at the pinion area, supporting clean lubricant retention and consistent driveline operation.

Key Features

• Nitrile construction for sealing performance and fluid resistance
• Inside diameter: 1.825 in.
• Outside diameter: 2.754 in.
• Housing bore: 2.75 in.
• Width: 0.468 in.
• Shaft diameter: 1.825 in.
• Part number: WS7600S

Detailed Description

This InMotion differential pinion seal is engineered to create a secure seal around the pinion shaft area, helping keep debris and moisture out of the differential while retaining lubricant inside the housing. The nitrile material is selected for sealing durability in driveline environments, and the dimensional specs support accurate service selection when replacing a worn or leaking seal. For technicians servicing axle and driveline components on applications such as Ford F-150 or Chevrolet Silverado 1500, WS7600S provides a direct-fit sealing solution when the listed dimensions match the original component. The part number WS7600S is also useful for catalog matching during differential pinion seal replacement on compatible truck and SUV driveline assemblies.

Common Problems This Seal Addresses

• Gear oil seepage at the differential pinion area
• Contamination from road debris and moisture entering the housing
• Seal wear that leads to driveline fluid loss
• Noise or driveline concerns associated with low lubricant level
• Service replacement for a damaged pinion seal during axle maintenance

Installation Notes and Tips

Verify the inside diameter, outside diameter, width, shaft diameter, and housing bore against the original seal before installation. Inspect the pinion yoke and sealing surface for wear, scoring, or corrosion, since surface damage can affect seal life. Clean the bore thoroughly and install the seal squarely to avoid distortion. Confirm proper differential fluid level after service. If you are cross-referencing by catalog, WS7600S should be matched to the exact application before installation on Ford F-150 or Chevrolet Silverado 1500 driveline assemblies.

Quality Assurance

InMotion manufactures this seal with precision-focused construction and high-quality materials to support reliable differential sealing performance. The design emphasizes contaminant exclusion and leak control for long-term driveline service.
