Detailed Description

National 710454 is engineered as a precision wheel seal for axle and hub sealing service. The fluoro-elastomer material helps maintain sealing integrity under demanding operating conditions, while the bi-directional lip design supports sealing in either rotational direction. With its specified shaft, housing bore, and outside diameter dimensions, this seal is intended for accurate fitment in applications that require controlled oil retention and protection against road contamination. If you are servicing a Ford F-250, Ford F-350, or similar axle-equipped vehicle that uses this seal specification, National 710454 provides the dimensional match needed for a proper repair. The 710454 part number is also useful when cross-checking replacement needs against OE-style references and aftermarket interchange listings.

This part cross-references Gates 34928 for the same application.

What It Helps Address

• Gear oil leakage at the wheel end
• Contamination entering the hub or axle seal area
• Seal wear from heat, friction, and age
• Loss of sealing performance after axle or hub service
• Noise or driveline issues related to low lubricant retention

Installation Notes and Tips

Verify shaft diameter, housing bore, and seal width before installation. Clean the sealing surface and inspect the hub or axle journal for scoring, corrosion, or wear that could affect seal life. Confirm the seal orientation matches the application and press the seal in evenly to avoid distortion. For fitment-based searches, this part is commonly referenced for Ford F-250 and Ford F-350 axle service, so compare the dimensions and OE number before installation. National 710454 should be matched to the exact application listed by the vehicle service information.
