FAG SS3226 Differential Pinion Seal - Rear or Rear Inner

FAG SS3226 Differential Pinion Seal

The FAG SS3226 differential pinion seal is built for rear axle sealing applications that demand accurate dimensions and durable sealing materials. With Viton sealing material and a rubber, spring, auxiliary lip, and inner shell design, it helps maintain axle lubrication while keeping out dirt, dust, and moisture.

Use this seal for select Ford F-250 Super Duty, Ford F-350 Super Duty, Dodge Ram 2500, Dodge Ram 3500, Jeep Cherokee, Jeep Grand Cherokee, Dodge Viper, Ford E-350 Super Duty, and Chevrolet Corvette rear axle applications where the listed dimensions and position match.

Detailed Description

FAG SS3226 is a differential pinion seal designed for rear axle sealing where precise fit and material stability matter. The Viton sealing surface is paired with a spring-loaded, auxiliary-lip construction to help maintain contact at the sealing edge, while the inner shell supports the seal structure. These dimensions and materials make it a strong match for driveline service on vehicles such as the Ford F-250 Super Duty, Ford F-350 Super Duty, and Dodge Ram 2500 and Ram 3500 rear axle applications when the OE specification calls for this size.

This part cross-references Gates 24816 for the same application.

What It Helps Address

• Rear differential pinion seal leakage
• Gear oil loss at the axle pinion area
• Contamination from dirt, dust, and moisture entering the seal area
• Seal wear from age, heat, and driveline exposure
• Noise or driveline concerns caused by low lubricant level

Installation Notes and Tips

Confirm bore diameter, outside diameter, width, and axle position before installation. This seal is listed for rear and rear inner positions on select applications, including Dana 80 axle notes on certain Dodge Ram 2500 and Ram 3500 models. Inspect the pinion surface, housing bore, and surrounding components for wear or damage before pressing in the new seal. Proper alignment and clean sealing surfaces are important for reliable operation.

Quality Assurance

FAG designs seals to meet vehicle manufacturer specifications and works with suppliers to maintain its quality standards. The SS3226 follows that approach with application-specific dimensions and sealing materials for driveline service.
