FAG SS6231 Wheel Seal - Rear

Wheel Seal for Sprinter Rear Axles

FAG SS6231 is a rear wheel seal built for demanding wheel-end service on Mercedes-Benz Sprinter 2500 and Sprinter 3500 dual rear wheel applications, as well as earlier Dodge Sprinter models. It uses a Viton sealing material with a rubber, spring, and auxiliary lip design to help keep contamination out and retain grease at the bearing.

Key Features

• Wheel seal for rear axle applications
• Seal type: rubber, spring, auxiliary lip
• Sealing material: Viton
• Bore diameter: 3.858 in. / 97.993 mm
• Seal outside diameter: 3.897 in. / 98.984 mm
• Seal width: 2.933 in. / 74.498 mm
• Cross-reference: SKF 29475A

Detailed Description

FAG SS6231 is engineered for wheel-end sealing where dirt, dust, and moisture can shorten bearing life. The Viton sealing material and multi-lip construction are specified for applications that need consistent sealing performance under demanding operating conditions. This part cross-references SKF 29475A for the same application. It is a direct-fit wheel seal for rear positions on Mercedes-Benz Sprinter 2500 and Sprinter 3500 dual rear wheel models, and it also applies to 2007-2009 Dodge Sprinter 2500 and Sprinter 3500 rear axle service. FAG SS6231 is built to match vehicle-specific requirements for bore, outside diameter, and width.

What It Helps Address

• Grease loss at the wheel bearing
• Contamination from dirt and dust
• Moisture intrusion at the wheel end
• Seal wear from demanding rear axle service
• Fitment issues when replacing a worn rear wheel seal

Installation Notes and Tips

Verify bore diameter, seal outside diameter, and seal width before installation. Confirm rear axle application and dual rear wheel configuration for Mercedes-Benz Sprinter 2500 and Sprinter 3500 models, as well as 2007-2009 Dodge Sprinter 2500 and Sprinter 3500. Inspect the hub, bearing surfaces, and sealing area for wear or damage before pressing in the new seal. Clean all mating surfaces thoroughly so the seal lip can seat evenly.

Quality Assurance

FAG designs wheel seals to meet vehicle manufacturer specifications and works with suppliers to maintain FAG quality standards. The seal construction is selected to protect wheel-end components from contamination and help preserve grease over the life of the bearing.
