Installation Notes and Tips
Verify shaft diameter, housing bore, and seal width against the existing part before installation. Clean the hub and sealing surfaces thoroughly, and inspect the spindle or shaft for grooves, corrosion, or damage that could affect sealing. Confirm the vehicle configuration notes for your Ford F-250 or Ford F-350, including brake type and front inner position, since the fitment varies by year and setup. Proper seating during installation is important to avoid distortion of the seal lip.
