A power steering pump provides the required hydraulic pressure to steer your automobile with minimal effort on the steering wheel. It directs fluid from the reservoir into the steering gear, which applies the correct amount of pressure to turn the wheels smoothly.

The power steering pump is an important part of a vehicle and should be replaced when critical problems are detected. For instance, a whining noise while turning the wheel may be an indicator to replace this part. This may need to be replaced as quickly as possible. Also, when the steering wheel is slow to respond, this may cause this part to need replacing. Squealing and groaning noises from this system means that it should be replaced.
