What It Helps Address

• Front hub oil leakage at the wheel seal area
• Contamination entering the hub or axle sealing surface
• Worn or damaged original seal dimensions
• Service replacement needs on Ford E-Series front inner axle positions
• Seal wear related to age, mileage, or heat exposure

Installation Notes and Tips

Verify shaft, housing bore, and width measurements before installation to confirm the seal matches the application. Inspect the sealing surface for scoring, corrosion, or debris, and clean the bore thoroughly before pressing the seal into place. For Ford E-150 and Ford E-250 front inner service, confirm the exact model year and position, since fitment varies by chassis and production date. For 2001 applications, note the listed from 11/30/2001 coverage on select Ford E-250 Econoline, E-350 Econoline Club Wagon, and E-350 Super Duty front inner vehicles.
