InMotion WS1012N Wheel Seal

Wheel Seal for Differential and Transmission Service

The InMotion WS1012N is a nitrile wheel seal built to help maintain a clean, tight sealing surface in driveline and transmission applications. With precise dimensions and a compact 0.315-inch width, it is suited for service work where controlling fluid loss and keeping contaminants out is critical.

Compatible With BMW M3 rear applications with BMW 210 Differential, BMW 740i rear applications with BMW 215 Differential, and Porsche 911 front inner applications, this seal supports a wide range of import driveline service needs. The WS1012N is also used in select Audi, Saab, Mercedes-Benz, Volkswagen, Mazda, Ford, and Maserati applications.

• Inside diameter: 1.772 in.
• Outside diameter: 2.453 in.
• Housing bore: 2.441 in.
• Thickness and width: 0.315 in.

Detailed Description

InMotion WS1012N is engineered as a precision seal for driveline and transmission service, using nitrile material to form a secure barrier at the sealing point. Its dimensions are specified for proper fitment at the shaft and housing interface, helping reduce the chance of leaks while protecting internal components from contamination. This makes the WS1012N a practical choice for maintenance on BMW M3 and BMW 740i rear differential service, as well as Porsche 928 and Porsche 944 front inner seal applications.

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 or seal surface
• Contamination from road debris and moisture
• Seal wear that can lead to fluid loss
• Service needs on rear differential and transmission assemblies
• Fitment-specific replacement on import driveline systems

Installation Notes and Tips

• Verify shaft diameter, housing bore, and seal width before installation.
• Inspect the sealing surface for grooves, corrosion, or damage before pressing in the new seal.
• Use the vehicle position and notes in the fitment list to confirm the correct application.
• For BMW 210 and 215 differential applications, match the differential type exactly.
• For Audi, Saab, and Porsche applications, confirm transmission or hub configuration where noted.
