The National 710701 axle spindle seal is a critical component in the driveline and axle sealing system, specifically designed to fit Ford Excursion, F-250 Super Duty, and F-350 Super Duty models.

- Use appropriate tools to press the seal evenly into the housing bore without distortion
- Inspect the shaft for wear or damage prior to seal installation
- Apply a light coating of lubricant on the seal lip to ease installation and prevent damage
