What It Helps Address

• Moisture entering the bearing area
• Wear caused by contaminated wheel-end lubrication
• Seal replacement during front hub and bearing service

Installation Notes and Tips

Verify bore diameter, seal outside diameter, and seal width before installation to confirm the correct fit for the hub or spindle assembly. Inspect the spindle, hub bore, and bearing surfaces for wear, scoring, or corrosion before pressing in the new seal. Clean all sealing surfaces thoroughly and install the seal squarely to avoid distortion. Confirm whether your vehicle uses the front inner or front outer position, since fitment varies by model year and axle location.
