Installation Notes and Tips

Verify the bore diameter, outside diameter, and seal width against the original seal before installation. Confirm whether the vehicle uses a front inner or front outer seal position, since fitment varies by application. Inspect the hub, spindle, and bearing surfaces for wear or damage before installing the new seal, and make sure the sealing lip seats evenly during assembly.
