National wheel seal for Chevrolet Silverado 2500 HD 2001–2010, 710568 spring-loaded multi-lip

National 710568 is a direct-fit wheel seal engineered to restore reliable axle sealing on compatible Chevrolet and GMC heavy-duty vans and trucks from the early 2000s.

When you're rebuilding hubs or servicing axles on a Silverado 2500 HD (2001–2010) or other supported Express and Silverado models, choosing a high-quality wheel seal matters. National has produced sealing components for over 75 years; the 710568 wheel seal combines a spring-loaded, multi-lip design with compound resistance to common lubricants and hydrocarbons to help the hub assembly keep grease in and contaminants out.

Which vehicles will this National wheel seal fit?

This seal is specified for a range of Chevrolet Express and Silverado applications across overlapping model years. Fitment varies by year, model, engine, and trim, so always verify your vehicle details before purchasing.

• Commonly fits 2001–2010 Chevrolet Silverado 2500 HD models (verify specific years and trims).
• Also used on select Chevrolet Express 2500/3500 and Express 4500 model years listed by the manufacturer.
• Check vehicle year, make, model, engine and trim against the confirmed-fit notes on the sales page.

How is this seal constructed and what operating conditions does it handle?

The National 710568 uses a spring-loaded, multi-lip geometry to maintain contact pressure and keep lubricant retention effective under rotation and axial movement. The material selection minimizes swelling in hydrocarbon-based fluids and provides resistance to extreme-pressure (EP) lubricants.

• Design type: spring-loaded multi-lip for continuous sealing contact.
• Temperature capability: specified range from -20°F to 300°F (-29°C to 149°C).
• Formulated for low swell in hydrocarbon fluids and protection from EP lubricants.

What problems does replacing the wheel seal solve?

Worn or damaged wheel seals are a common cause of grease loss and axle contamination. Installing a new National 710568 helps prevent lubricant leakage, keeps dirt and water out of the hub, and supports longer bearing life when installed correctly.

• Stops hub grease from leaking onto brakes and suspension components.
• Reduces risk of abrasive contaminants reaching bearings and races.
• Restores proper sealing clearance and pressure with the spring-loaded lip.

Who is this for: mechanics, fleet service technicians, and do-it-yourself owners performing hub or axle service on compatible Chevrolet Express and Silverado heavy-duty models. If you're rebuilding hubs, replacing bearings, or addressing grease leakage on a 2001–2010 Silverado 2500 HD, this National wheel seal is engineered to be a reliable OEM-style replacement—just confirm exact vehicle fitment before ordering.
