Detailed Description
National has supplied sealing solutions for more than 75 years, and the 710701 reflects that focus with a design intended for today’s axle service requirements. The polyacrylate construction and OE-style dimensions help maintain a proper seal at the spindle area, where front axle components are exposed to road debris, moisture, and lubricant movement. For Ford F-250 Super Duty and Ford F-350 Super Duty front axle repairs, this seal is specified to match the listed housing bore, shaft size, and width requirements.
Use the National 710701 when replacing a worn or leaking front axle spindle seal on compatible Ford Super Duty and Excursion applications. The seal is also referenced under National 710701 in interchange listings, making it a practical match for parts lookup and service verification.
Common Problems This Seal Can Address
- Front axle lubricant seepage at the spindle area
- Contamination entering the axle assembly through a worn seal
- Oil residue around the hub or knuckle area
- Seal wear from age, heat, or road exposure
- Loss of sealing performance during axle service on Ford Super Duty trucks
Installation Notes and Tips
Confirm axle configuration before ordering, especially on 2005-2018 Ford F-250 Super Duty and Ford F-350 Super Duty models with Spicer 60-SF axle(s), Monobeam axle(s), and 9.75-inch ring gear. Inspect the spindle, housing bore, and sealing surface for wear or scoring before installation. Clean the bore thoroughly and verify the seal seats squarely to the specified dimensions. Always compare the old seal to the new part number 710701 and confirm the front position match before assembly.
Quality Assurance
National is recognized for sealing products backed by more than 75 years of industry experience. The 710701 is engineered as a precision oil seal for axle service and is supported by National’s long-standing focus on fit and sealing performance.
