Installation Notes and Tips

Confirm bore diameter, outside diameter, and seal width against the original part before installation. Inspect the hub, spindle, and bearing surfaces for wear or scoring, and replace damaged components as needed. Clean the sealing surface thoroughly so the new wheel seal seats evenly and maintains proper contact.
