FAG SS2990 Axle Spindle Seal - Front

FAG SS2990 Axle Spindle Seal

The FAG SS2990 axle spindle seal is built for front wheel-end service where sealing accuracy matters. It uses a nitrile sealing material with a metal case, spring, and auxiliary lip to help keep contaminants out and retain grease at the bearing.

Compatible with select Chevrolet Blazer, Chevrolet K10 Suburban, Chevrolet K20 Suburban, Ford Bronco, and Ford F-250 front applications, this seal is specified for demanding wheel-end environments. The FAG SS2990 is sized with a 3.000 in bore diameter, 3.005 in outside diameter, and 1.938 in width.

Detailed Description

FAG SS2990 is engineered for wheel-end sealing where protection against dirt, dust, and moisture is critical. Its construction is intended to help preserve grease at the bearing and support long-term wheel-end reliability in front axle service. This part number is used in applications such as 1966-1972 Ford Bronco front, 1960-1972 Ford F-250 front, and select Chevrolet Blazer and Suburban front driveline setups. The FAG SS2990 also cross-references Davico Mfg 19360 for the same application.

What It Helps Address

• Grease loss at the wheel bearing area
• Contamination from road dirt and dust
• Moisture intrusion at the spindle seal surface
• Wear related to compromised wheel-end sealing
• Front axle service issues on older 4WD and AWD vehicles

Installation Notes and Tips

Verify bore diameter, outside diameter, and seal width before installation. Confirm front axle application and vehicle-specific fitment for the exact year and model, including notes such as AWD or 4WD where listed. Inspect the spindle, hub, and bearing surfaces for wear or scoring before installing the new seal.

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 meet the demanding requirements of wheel-end service and help protect bearing components over time.
