Technical Specifications and Features

The National 710081 wheel seal is constructed from nitrile, a synthetic rubber known for its resistance to oil, heat, and wear. The seal’s inside diameter of 1.929 inches (49 mm) matches the shaft size, while the outside diameter of 3.945 inches (100.2 mm) fits securely within a housing bore of approximately 3.937 inches (100 mm). With a width of 0.315 inches (8 mm), this seal is designed to maintain a tight fit and prevent lubricant leakage in axle and driveline assemblies.

Applications and Compatibility

This wheel seal is compatible with a range of vehicles that require a 49 mm shaft seal, including certain Ford, Chevrolet, and Dodge models commonly found in light trucks and SUVs. The National 710081 part number is often sought for replacement in driveline and axle maintenance where oil seals are critical to system integrity.

• Prevents oil leaks in axle assemblies
• Protects driveline components from dirt and contaminants
• Maintains lubrication within wheel hubs
• Reduces wear on shafts and bearings
• Ensures proper sealing in high-temperature environments

Installation Notes and Tips

When installing the National 710081 wheel seal, ensure the housing bore is clean and free of debris. Use appropriate tools to press the seal evenly into place without damaging the sealing lip. Lubricate the seal lip lightly with compatible grease or oil before installation to reduce initial wear. Verify shaft dimensions to confirm fitment and avoid premature seal failure.
