Power Steering Pump FAQ
-
What does a power steering pump do?
-
The power steering pump generates hydraulic pressure to assist the driver in turning the steering wheel more easily. It supplies pressurized fluid to the power steering rack, reducing steering effort—especially at low speeds.
-
What are the symptoms of a failing power steering pump?
-
Common signs include:
- Whining or groaning noises when turning the steering wheel
- Leaking power steering fluid
- Heavier-than-usual steering
- Fluid foaming in the reservoir
- Jerky or inconsistent steering response
-
What causes a power steering pump to fail?
-
Possible causes include:
- Worn internal components (vanes, bearings, seals)
- Contaminated or low fluid
- Faulty flow control valve
- Loose or worn power steering belt
- Problems with the steering rack
-
Should I replace my alternator with a used, rebuilt, or brand-new unit?
-
Each option has its pros and cons:
- Used Power Steering Pump:
Affordable, but condition and lifespan are uncertain. Internal wear may not be visible, and there’s no guarantee how long it will last. Best suited for short-term use or temporary fixes. - Rebuilt Power Steering Pump:
A cost-effective and reliable option when rebuilt by professionals using genuine components. It’s fully inspected, worn parts are replaced, and performance is restored. Ideal for those seeking quality and savings. - Brand-New Power Steering Pump:
Offers maximum reliability and warranty coverage, but typically comes at a higher price. Best for those prioritizing long-term peace of mind and minimal downtime.
- Used Power Steering Pump:
