Detailed Description

National 474230 is engineered as a wheel seal with a 73.000 mm shaft diameter, 90.120 mm outside diameter, and 8.000 mm width. The nitrile sealing material is commonly used in automotive sealing applications for its ability to maintain contact and help control lubricant leakage at the wheel end. National has focused on premium sealing solutions for decades, and this seal reflects that experience in a metric OE-style format.

This part cross-references SKF 28325 for the same application. If you are servicing a Honda Civic or comparing replacement options for axle and wheel-end sealing, National 474230 offers the dimensional details needed to match the original seal specification.

What This Seal Helps Address

• Oil seepage at the wheel end
• Contamination entering the sealed area
• Wear-related seal leakage during axle service
• Replacement needs after hub or driveline maintenance
• Dimensional mismatch when sourcing a metric wheel seal

Installation Notes and Tips

Verify shaft, housing bore, and width measurements before installation to confirm the seal matches the application. Inspect the sealing surface for scoring, corrosion, or debris, and clean the bore thoroughly before pressing the seal into place. Use care to keep the sealing lip aligned during installation so the nitrile material seats evenly.

For Honda Civic wheel seal replacement or other metric axle sealing jobs, confirm the original dimensions against the removed part before assembly. National 474230 should be installed on a clean, smooth surface to support proper sealing performance.
