What is a power steering pump and how does it work?
A power steering pump uses hydraulic pressure to make it easier for a driver to turn the steering wheel. Power steering is featured on nearly all vehicles today. Without power-assisted steering, turning the wheel would be very difficult, especially when traveling slowly, when stopped, or while parking. Although the automotive industry is beginning to see many late-model vehicles that feature electric-assist power steering systems, still the majority rely on hydraulic power. The power steering pump is the heart of the system, pressurizing the oil (power steering fluid) to exert force - up to 1000 psi in some vehicles - for steering assist.
How do I know if my power steering pump needs to be replaced?
If your power steering pump is bad or failing, there is a good chance that you will notice symptoms when you are driving. If you notice any of the following, make sure to have your steering system inspected to determine if your pump is bad
You hear a growling, humming, or whining noise coming from under the hood. This sound will often grow louder when you turn the steering wheel
Your steering wheel becomes abnormally hard to turn
The steering wheel shakes or jerks during turning maneuvers
Upon inspection, you (or a technician) notice metallic particles inside the power steering fluid reservoir
