Installation Notes and Tips
Confirm the shaft diameter, housing bore, and seal width before installation. Inspect the sealing surface for wear, scoring, or corrosion, and clean the bore thoroughly so the new seal seats evenly. Match the front inner position exactly to the vehicle application listed for your Toyota Corolla or Toyota Celica.

National states that it has provided premium sealing solutions for more than 75 years and continues to develop sealing products for modern vehicle requirements. Use the confirmed dimensions and fitment data to verify National 1950 before installation.
