What causes a power steering pump to fail?

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.
