Installation Notes and Tips

Verify shaft diameter, housing bore, and seal width before installation to confirm the seal matches the application. Inspect the axle shaft and seal bore for wear, scoring, or corrosion, and clean the sealing surfaces before pressing the seal into place. Confirm the seal is seated evenly to avoid leaks after reassembly.
