After you've ruled out low fluid in the power steering reservoir, there are a few signs of a failing power steering pump. If you hear a whining or growling noise when you turn the wheel, check the fluid level in the reservoir. If topping off the fluid doesn’t fix the noise, chances are you’ll need to replace the pump. Difficulty turning the steering wheel or excess vibration of the wheel, even at idle, are also signs of a failing pump. Shop with us to find new and remanufactured power steering pumps from brands you can trust, like Carquest® Premium, Cardone™, ACDelco®, Maval® and more.
