Technical Details and Specifications

This National wheel seal (part number 205017) is part of the 205000 series and is constructed from felt material, which offers effective oil sealing properties in axle and driveline assemblies. The seal’s inside diameter of 1.625 inches (41.280 mm) matches the shaft size, while the outside diameter of 2.332 inches (59.230 mm) fits securely within the housing bore of 2.328 inches (59.130 mm). The 0.406 inch (10.310 mm) width ensures a proper seal thickness to prevent oil leakage and contamination.

Applications and Problem Solving

This wheel seal is commonly used in automotive driveline and axle systems to maintain lubrication and prevent contaminants from entering the bearing area. It is compatible with vehicles requiring a 1.625 inch shaft seal, including certain Ford, Chevrolet, and Dodge models that specify National 205017 or equivalent seals.

• Prevents oil leaks in axle assemblies
• Protects bearings from dirt and debris
• Maintains proper lubrication in wheel hubs
• Reduces wear and extends component life
• Helps avoid costly driveline repairs

Installation Notes and Tips

When installing the National 205017 wheel seal, ensure the shaft and housing bore are clean and free of debris. Use appropriate tools to press the seal evenly into the housing bore without damaging the felt material. Verify the seal orientation matches the oil side to maximize sealing efficiency. Lubricate the seal lip lightly before installation to reduce initial wear.
