Power steering is what makes an ordinary driving experience extraordinary by adding to the power you apply to the steering wheel and making it simpler to turn the wheel. The power steering pump is the secret weapon in this system, allowing you to efficiently turn your vehicle for years without worrying about a single problem.
The power steering pump has a fluid reservoir that is automatically controlled by the gears with a sole purpose of providing a precise flow of fluids to the steering mechanisms to ensure that they stay responsive to the driver's every movement.
There are three key styles of power steering pumps: roller, slipper, and vane.
Vane: Vane power steering pumps are by far the most widely-used, and trap the power steering fluid before pressure increases force the fluid to leave the housing.
Roller: Roller power steering fluid pumps utilize centrifugal force to grab the fluid as it is pressurized and before it is pushed through the pump's outlets.
Slipper: Slipper-style power steering pumps require springs to assist them in adding pressure to and then releasing the fluid.
Regardless of the style, pressure-resistant steering pumps are by far the preferred part, as it takes a large amount of pressure to force the steering fluid to move easily.
Check your owner's manual before making a purchase to be sure you're getting the right type of power steering fluid pump for your vehicle. While your system may not require you to put exactly the same style of pump on your car, you will need to be sure that your vehicle will accept the type of pump you want to purchase.
Note: While second-hand, refurbished pumps are available and will cost much less, don't go in this direction unless your budget is incredibly tight. The reconditioned pumps may not work much better than your old pump. When in doubt, use an original equipment manufacturer (OEM) part.
