Installation Notes and Tips

Confirm the vehicle uses the Borg Warner 4485 front output shaft application before installation. Inspect the shaft surface for wear, scoring, or corrosion, and clean the sealing area thoroughly so the new seal seats evenly. Proper alignment during installation helps protect the reinforced case and the sealing lip.
