Detailed Description

InMotion WS225450 is engineered to maintain a tight seal at the differential pinion area, helping keep contaminants out and lubricant in. The seal’s nitrile construction, steel case materials, and precision dimensions support consistent fitment in front inner applications such as 2000-2004 Volvo S40 and 2000-2004 Volvo V40, as well as 1990-1994 Mitsubishi Eclipse and 1990-1994 Plymouth Laser front inner service locations. The WS225450 is also listed for 1988-1993 Mitsubishi Galant, 1989-1990 Mitsubishi Sigma, 1992-1995 Mitsubishi Expo, and 1992-1994 Mitsubishi Expo LRV front inner positions.

What It Helps Address

• Gear oil seepage at the differential pinion seal area
• Contamination from road debris and moisture
• Seal wear that can lead to reduced sealing integrity
• Service replacement needs on front inner driveline sealing points
• Fitment-specific repair work on Volvo S40, Volvo V40, Mitsubishi Eclipse, and Plymouth Laser applications

Installation Notes and Tips

Confirm the housing bore, shaft diameter, and seal dimensions before installation. Clean the sealing surface thoroughly, inspect the pinion area for wear or scoring, and install the seal squarely to avoid distortion. For fitment verification, match the application to the listed front inner positions for the exact year and model. WS225450 should be checked against the removed part and vehicle service data before assembly.

Quality Assurance

InMotion WS225450 uses nitrile sealing material with SAE 1008 spring material and SAE 1070 seal case material for a precision-built replacement. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
