What It Helps Address

• Fluid leakage at the power steering pump shaft
• Contamination entering the steering pump area
• Seal wear from age, heat, and fluid exposure
• Loss of sealing pressure at the pump shaft interface

Installation Notes and Tips

Confirm bore diameter, outside diameter, and seal width before installation. Inspect the shaft surface, housing, and surrounding steering components for wear or scoring before fitting the new seal. Clean all sealing surfaces thoroughly and verify the seal is seated evenly to maintain proper contact.

Quality Assurance

FAG designs seals to meet vehicle manufacturer specifications and works with suppliers to maintain FAG quality standards. The sealing construction is selected to protect wheel-end and steering-related components from dirt, dust, and moisture while helping retain grease or fluid where required.
