Installation Notes and Tips

Verify the rear inner position, seal dimensions, and chassis notes before installation. Confirm the bore diameter, outside diameter, and width against the removed seal and the vehicle application.

Clean the hub and bearing area thoroughly before installing the new seal to avoid contamination during assembly.
