Audi Power Steering Pump - Bosch ZF 4H0145155D

Product Information

Power steering pumps pressurize the fluid in the steering hydraulic system to allow for steering assist at slow road speeds. The power steering system is powered by the engine via a serpentine or v belt which spins the pump pulley. Power steering pumps are generally a lifetime component.

However, poor power steering system maintenance, old power steering fluid, and incorrect power steering fluid can cause the pump to fail prematurely. If your power steering pump is screaming or chirping when you are turning the wheels you may need to replace it.

• Leaks at seals
• Squeaking or squealing sounds
• Heavy steering feel at slower road speeds
• Whining noise when turning the steering wheel
