What This Seal Helps Address

• Transfer case fluid seepage at the output shaft

• Grease or lubricant loss around the shaft area
• Wear-related sealing issues on high-mileage drivetrain components
• Service replacement needs on Ram, Dodge, Chevrolet Silverado, and GMC Sierra transfer cases

Installation Notes

Verify shaft diameter, bore diameter, and seal width before installation. This FAG SS3159 seal is specified for applications with a 2.205 in. shaft in many listings, including New Process 241, 261, and 263 transfer case setups. Clean the sealing surface thoroughly and inspect the shaft for grooves or damage before pressing in the new seal. For long-term sealing performance, confirm the transfer case model and rear output application against the vehicle listing.

Quality Assurance

FAG designs seals to meet vehicle manufacturer specifications and works with suppliers to maintain its quality standards. The SS3159 uses Viton sealing material and a reinforced seal construction for drivetrain service where consistent sealing is required.
