Detailed Product Description

The National 4099 wheel seal is constructed from nitrile, a material known for its resistance to oil, heat, and wear, making it suitable for demanding automotive environments. This seal features a flanged outside diameter of 2.500 inches (63.5 mm) to ensure a secure fit within the housing bore of 2.162 inches (54.91 mm). The precise inside diameter of 1.673 inches (42.49 mm) matches the shaft size for optimal sealing performance. The Redicoat treatment adds a protective layer to prevent corrosion and extend the seal’s service life. As part of the National 4000 series, this seal meets industry standards for durability and reliability in driveline and axle sealing systems.

Compatible Vehicles and Applications

This wheel seal is compatible with a range of Chrysler, Dodge, and Plymouth models, including but not limited to the Chrysler New Yorker, Dodge Charger, Plymouth Sundance, and others such as the Acclaim, Aries, Daytona, Dynasty, Expo, Imperial, Lancer, Laser, LeBaron, Rampage, Reliant, Shadow, Spirit, Town & Country, Turismo, and Turismo 2.2. The National 4099 is designed to maintain proper oil retention and prevent dirt ingress in these vehicles’ wheel hubs and axle assemblies.

Common Issues Addressed by National 4099 Wheel Seal

  • Prevents oil leaks from wheel hubs and axle assemblies

Ensure the housing bore and shaft surfaces are clean and free of debris before installation. Use appropriate tools to press the seal evenly into the bore without damaging the flange or sealing lip. Verify the seal orientation matches the original part to maintain proper sealing function. Avoid using excessive force during installation to prevent distortion or damage to the nitrile material.
