Detailed Description

InMotion WS1928 is a differential pinion seal designed around the listed dimensions for accurate service replacement. By creating a tight barrier at the pinion area, it helps reduce the risk of gear oil leaks and limits contamination that can shorten differential life. This part number, WS1928, is a practical choice for rear inner and rear outer applications across select Lexus and Toyota vehicles, including 1990-2000 Lexus LS400 rear inner, 1992-2000 Lexus SC300 rear inner, 1992-2000 Lexus SC400 rear inner, 1987-1998 Toyota Supra rear outer, 1993-1997 Lexus GS300 rear inner, and 1989-1992 Toyota Cressida rear outer. 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
• Contamination from dirt, moisture, and road debris
• Seal wear that can lead to driveline fluid loss
• Service needs on rear inner and rear outer differential positions
• Replacement needs for Lexus LS400, SC300, SC400, GS300, and Toyota Supra or Cressida applications

Installation Notes and Tips

Verify shaft diameter, housing bore, and seal width before installation to confirm the correct match for WS1928. Clean the sealing surfaces thoroughly and inspect the pinion area for wear, scoring, or damage before pressing in the new seal. For fitment-specific service, confirm the vehicle position listed for your application, such as rear inner or rear outer.
