Detailed Description

National 370211A is a wheel seal in the 370000 series, identified as an oil bath seal with Type 11 construction. It is engineered around the listed housing bore and shaft diameter measurements to support a proper seal at the wheel end, helping maintain lubricant retention and reduce contamination at the spindle mount interface. This part cross-references SKF 29400 for the same application.

For buyers searching for a National 370211A wheel seal, OE-style oil bath seal, or spindle mount wheel seal replacement, this part is specified by exact dimensions rather than broad vehicle coverage. Confirm the housing bore, shaft diameter, and installation tool requirement before ordering for your Honda Civic or other vehicle using this seal specification.

What This Part Helps Address

• Oil leakage at the wheel-end seal area
• Contamination entering the hub or bearing cavity
• Wear from an aging or hardened seal lip
• Improper sealing after wheel-end service
• Noise or bearing issues caused by lubricant loss

Installation Notes and Tips

Use installation tool RD316 for installation. Verify the housing bore, outside diameter, shaft diameter, and width against the original seal before pressing the seal into place. Clean the spindle and housing surfaces thoroughly, and inspect the mating surfaces for wear, scoring, or corrosion before installing National 370211A.

Because this is a dimension-specific wheel seal, confirm the application by measurement and service information for the exact vehicle. For fitment-based searches, this part is commonly referenced in wheel-end service for Honda Civic applications and other vehicles using the same seal dimensions.
