Keep wheel-bearing lubricant sealed in and road grit sealed out with the Timken Wheel Seal 4148, a grease/oil seal that installs as a direct-fit replacement for a wide range of Ford trucks and vans — from the 1965-1972 Ford F-100 and 1975-2003 F-150 to the 1975-2002 E-150 Econoline, the 1997-2002 Expedition, and the 1998-2002 Lincoln Navigator. See the Buyer's Guide tab for the full list of 17 applications.
- Precision sealing design: helps prevent lubricant escape while keeping harmful contaminants from entering.
- Reinforced outer case: helps prevent installation damage and enhances durability.
- Ribbed rubber inner diameter: designed to seal minor spindle imperfections and promote positive spindle seating.
- Internal contamination exclusion system: helps block debris penetration that may lead to leakage.
- Vent holes: allow lubricants to flow freely around the seal lip, cooling the seal components and removing heat build-up.
The seal body seats in its bore and stays stationary while its lip rides against the rotating spindle/shaft, retaining wheel-bearing lubricant and excluding dirt and moisture. Signs this seal may need replacing include grease seeping near the hub, contaminated bearing lubricant, or bearing noise — if a leaking wheel seal is the cause, this replaces it. The listed applications use two seals per vehicle, so order enough to cover both sides. Manufacturer part number 4148.

Frequently Asked Questions
What is the Timken 4148?
It is a grease/oil wheel seal that retains wheel-bearing lubricant while keeping dirt, moisture, and contaminants out of the bearing.
Which vehicles does it fit?
It's a direct-fit replacement for a range of Ford trucks and vans and select Lincolns, including the F-100, F-150, F-250, E-150 Econoline, Expedition, and Navigator. See the Buyer's Guide tab for all 17 applications.
How many seals do I need?
The listed applications use two seals per vehicle, so order enough to cover both sides for a complete replacement.
What are signs this wheel seal may need replacing?
Grease seeping near the hub, contaminated bearing lubricant, or wheel-bearing noise. Diagnose the cause first, since these signs can have other sources.
Does the wheel seal rotate?
No. The seal body stays stationary in its bore, and its lip contacts the rotating spindle/shaft to hold lubricant in and contaminants out.
