Keep axle and differential lubricant sealed in with the National Axle Differential Seal / Wheel Seal 473823. This oil seal drops in as a direct-fit replacement across a wide list of applications, including the 1996-2000 BMW 328i, 2001-2006 BMW 325i, 2000-2009 BMW X5, 1972-1982 Ford Courier, 1986-1994 Nissan D21, and 1992-1998 Suzuki Sidekick — see the "Vehicles it fits" section for the full 55-application list.
- Seals the axle/differential: retains gear lubricant and helps block dirt, water, and road grime from entering.
- Position coverage: cataloged for front, rear, and rear-inner axle and wheel positions depending on the application.
- Stationary seal: the seal body stays fixed in its bore while the sealing lip rides against the rotating axle shaft.
- Direct-fit replacement: installs in place of the original seal on the listed applications.
A worn or hardened seal can let lubricant seep past the axle, leaving an oily film or drips near the hub and lowering the fluid level over time. If a failed seal is the cause of your leak, this replaces it — diagnose the leak source before installing.

Frequently Asked Questions
What does the National 473823 seal do?
It's an axle/differential oil seal that retains gear lubricant and helps keep out dirt, water, and grime where the axle shaft passes through the housing or hub.
What position does it fit?
It's cataloged for front, rear, and rear-inner axle and wheel positions depending on the vehicle. Check the "Vehicles it fits" section to match the correct location for your application.
Does the seal spin with the axle?
No. The seal body stays stationary in its bore while its lip rides against the rotating axle shaft to hold lubricant in.
How do I know the seal is failing?
Lubricant seepage or drips near the axle, hub, or differential and a dropping fluid level are common signs. Confirm the seal is the leak source before replacing.
Will it fit my vehicle?
It fits 55 applications, including BMW 328i, 335i, 528i, X3, X5, X6, Z3, Z4 plus Ford Courier, Nissan D21/Pathfinder, and Suzuki Sidekick/Vitara. See the "Vehicles it fits" section to confirm your year and model.
