Detailed Description

InMotion WS493637 is a wheel seal engineered for front inner use where accurate sealing dimensions matter. The nitrile sealing material helps form a tight interface against contaminants and moisture, supporting cleaner operation around sensitive differential pinion components. This seal is listed for 1975-1986 Ford and Jeep front inner applications, including 1975-1980 Ford E-250 Econoline, 1975-1980 Ford E-350 Econoline, 1976-1979 Ford F-250 with heavy duty brakes, 1976-1979 Ford F-350, 1984-1986 Jeep CJ7, and 1984-1985 Jeep Scrambler. If you are sourcing a front inner wheel seal for a Ford F-250 or Jeep CJ7, WS493637 provides the dimensional match needed for service work.

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

Installation Notes and Tips

Verify shaft diameter, housing bore, and width before installation. Clean the sealing surface thoroughly and inspect the mating area for scoring or wear that could affect seal retention. Confirm the vehicle position is front inner and match the application notes, including the 1981 Ford E-250 Econoline, E-250 Econoline Club Wagon, E-350 Econoline, and E-350 Econoline Club Wagon listings that apply to units built to 11/03/1980. For 1976-1979 Ford F-250, the listing applies with heavy duty brakes.
