Detailed Description

FAG designs wheel seals to meet vehicle manufacturer specifications and to protect wheel-end components from dirt, dust, and moisture while helping retain grease over the service life of the bearing. The SS3300 follows that approach with a nitrile sealing element and a metal spring construction that supports consistent sealing at the hub. For Ram 3500 rear wheel seal replacement or Dodge Ram 3500 rear axle service, the FAG SS3300 provides the dimensional fit and sealing profile required for the listed applications.

This part cross-references National 710563 for the same application.

Common Problems This Seal Can Address

• Grease loss at the wheel end
• Contamination from road dirt and dust
• Moisture intrusion into the hub area
• Wear related to a damaged or hardened seal lip
• Service issues on rear wheel-end bearing assemblies

Installation Notes and Tips

Verify the axle position, hub dimensions, and vehicle application before installation. Clean the sealing surface thoroughly and inspect the bearing, hub, and spindle for wear or scoring before pressing in the new seal. Use proper seal installation tools to avoid distorting the metal case or damaging the sealing lip.

Quality Assurance

FAG sources wheel seals to meet manufacturer specifications and works with suppliers to maintain its quality standards for wheel-end sealing applications.
