Detailed Description

FAG SS3299 is engineered to meet vehicle manufacturer specifications for wheel-end sealing. The seal is designed to protect bearing and axle components from dirt, dust, and moisture while helping retain grease over the service life of the bearing. Its measured dimensions and Viton sealing material make it a precise choice for Ram rear axle service where correct fitment is critical.

What It Helps Solve

• Grease leakage at the wheel end
• Contamination from road dirt, dust, and moisture
• Premature wear of bearing and axle components
• Seal fit issues caused by incorrect bore or outside diameter
• Noise or roughness related to compromised wheel-end sealing

Installation Notes and Tips

Verify the axle position, model year, and seal dimensions before installation. This FAG wheel seal is listed for rear inner and rear positions on specific Ram and Dodge Ram trucks, including 2019-2024 Ram 2500 rear inner, 2021-2024 Ram 3500 rear inner, 2011-2020 Ram 3500 rear, 2011-2028? No. Use only the confirmed fitment data for your vehicle and compare the seal type and measurements to the original part before service.

For best results, inspect the hub, spindle, and bearing surfaces for wear or damage before installing the new seal. Clean sealing surfaces thoroughly and confirm the application matches the listed rear axle configuration, including single rear wheel notes where specified.
