Installation Notes and Tips

Verify the bore diameter, outside diameter, seal width, and shaft size before installation. Confirm the vehicle year, make, model, transmission type, and rear-position notes in the fitment data before ordering. Clean the sealing surface thoroughly and inspect the shaft for wear, scoring, or corrosion that could affect seal life. Proper alignment during installation is important to avoid damaging the sealing lip or spring.
