FAG SS3320 Wheel Seal - Rear or Rear Inner

FAG SS3320 Wheel Seal for Rear Axles

The FAG SS3320 wheel seal is built for rear wheel-end sealing where contamination control and grease retention matter. It is a direct-fit style seal for select Dodge Sprinter 2500 and Sprinter 3500 rear applications, including dual rear wheel configurations.

• Wheel seal for rear wheel-end service
• Sealing material: Viton
• Seal type: rubber with spring and auxiliary lip
• Bore diameter: 3.74 in. / 94.996 mm
• Seal outside diameter: 3.749 in. / 95.225 mm
• Seal width: 2.953 in. / 75.006 mm
• Designed to help keep dirt, dust, and moisture out of the bearing area

FAG SS3320 is engineered to meet vehicle manufacturer specifications using materials selected for demanding wheel seal service. The Viton sealing material and multi-lip design are used to support a tight seal at the rear hub, helping protect wheel-end components from contamination while maintaining lubrication. This part cross-references National 710462 and SKF 29485 for the same application. It is a strong match for rear wheel seal replacement on 2003-2006 Dodge Sprinter 2500 and 2003-2006 Dodge Sprinter 3500 models with dual rear wheels.

What This Wheel Seal Helps Address

• Grease loss at the rear wheel bearing area
• Dirt and dust intrusion into the hub assembly
• Moisture entering the wheel-end sealing surface
• Wear related to a damaged or leaking rear seal
• Service needs on Dodge Sprinter 2500 and Sprinter 3500 rear hubs

Installation Notes and Tips

Verify bore diameter, seal outside diameter, and seal width before installation to confirm the correct rear axle application. Inspect the hub, spindle, and bearing surfaces for scoring or contamination before pressing in the new seal. For best results, install the seal squarely and avoid damaging the sealing lip during assembly. Confirm fitment for 2003-2006 Dodge Sprinter 2500 rear dual rear wheels and 2003-2006 Dodge Sprinter 3500 rear dual rear wheels before service.
