FAG SS3103 Wheel Seal - Front

Wheel Seal for Driveline Protection

The FAG SS3103 wheel seal is built for wheel-end service where contamination control and grease retention matter. It uses a metal seal type with nitrile sealing material to help protect bearing components from dirt, dust, and moisture while maintaining lubricant inside the assembly.

Compatible With select Mitsubishi Mirage, Dodge Colt, and Jeep CJ5 and Wagoneer front axle applications, this seal is sized for specific wheel-end requirements and vehicle class. The FAG SS3103 is a direct-fit style wheel seal for applications that call for a 3.000 in bore diameter, 3.005 in outside diameter, and 2.125 in width.

Detailed Description

FAG SS3103 is a wheel seal engineered to meet vehicle-specific sealing demands in driveline and axle service. The seal is designed around precise dimensional requirements and uses nitrile sealing material to support long-term wheel-end protection. In applications such as 1993-1999 Mitsubishi Mirage front inner, 1993-1995 Dodge Colt front inner, and Jeep CJ5 or Wagoneer front axle positions, correct seal sizing is critical to bearing life and clean operation. This FAG SS3103 seal helps maintain the grease barrier at the wheel end while limiting intrusion from road debris and moisture.

This part cross-references National 8430S for the same application.

What It Helps Address

• Grease loss at the wheel end
• Contamination from dirt, dust, and moisture
• Premature wear in wheel bearing components
• Seal leakage in front axle service
• Noise or roughness related to compromised wheel-end sealing

Installation Notes and Tips

• Verify bore diameter, outside diameter, and width before installation.
• Match the seal to the exact position listed for your vehicle, such as front inner or front.
• Inspect the hub, spindle, and bearing surfaces for wear or scoring before fitting the new seal.
• Use clean assembly practices to avoid contaminating the sealing lip during installation.
• Confirm the application details for Jeep CJ5 and Wagoneer front axle service, as notes vary by chassis and drivetrain configuration.

Quality Assurance

FAG designs wheel seals to meet vehicle manufacturer specifications and works with suppliers to maintain its quality standards. The SS3103 is built for demanding wheel-end sealing requirements and application-specific fitment.
