Keep lubricant in and road grime out with the Timken wheel seal, part number 4148, a grease/oil seal whose precision sealing design is intended to stop lubricant from escaping and keep harmful contaminants from getting in. It is a direct-fit replacement for many listed models, among them the 1975-2003 Ford F-150, 1965-1972 Ford F-250 and 1997-2002 Ford Expedition.
The catalog lists this seal for the front inner position, and each listed application uses two. If grease is seeping from the hub or contaminants are reaching the bearing area, a worn wheel seal may be the cause. Inspect the area before replacing the seal. See the "Vehicles it fits" section for the full list of Ford and Lincoln applications.
