What It Helps Solve

• Grease loss at the wheel bearing
• Dirt, dust, and moisture intrusion at the wheel end
• Seal wear from incorrect bore or outside diameter match
• Noise or roughness caused by contaminated bearing grease
• Service issues on front or rear wheel-end assemblies

Installation Notes and Tips

Verify the seal type, bore diameter, outside diameter, and width before installation. Match the application by year, make, model, and position, since this part is used in both front and rear locations depending on the vehicle. Confirm any listed notes such as ring gear, brake type, or production-date limits before ordering. For best results, inspect the hub and bearing surfaces for wear or damage before installing the new seal.

Quality Assurance

FAG wheel seals are engineered using high-quality materials and built to meet vehicle manufacturer specifications. The seal design is selected to protect wheel-end components from contamination and help retain grease over the life of the bearing.
