Due to the weight of a vehicle and the friction of the tires on the ground, steering a car can be difficult without help. Power steering systems utilize hydraulic pressure to reduce the effort drivers must exert to turn the wheel. However, regular wear and tear can take its toll on all components of a car, requiring auto repairs to get you back on the road safely. The following guide outlines how power steering works and how to handle any issues you might face.

How Does Power Steering Work?

Most modern vehicles use a rack and pinion steering system, where the steering wheel turns a circular gear called the pinion; this part meshes its teeth with a linear gear, also known as the rack. As the driver maneuvers the wheel, the pinion rotates, shifting the rack to the left or right. Since this part is attached to the wheel axles, it moves them in the same direction. 

However, to compensate for vehicle weight and tire friction, a hydraulic assist is used to amplify its forward momentum. This pump is powered by the engine and puts pressure on a fluid, and the connected lines transfer that force to a hydraulic piston. The piston pushes and pulls the rack in the appropriate direction to help the driver turn the wheel.

How Do You Handle Power Steering Failure?

A failed pump can lead to total power steering failure, and you'll find that directing the car takes much more effort—particularly when the vehicle isn't moving. A car isn't the safest to drive when it's in this state. A hose leak and low hydraulic fluid can cause a similar problem or make handling feel heavy and sluggish. 

If you experience total failure, slow the car by braking carefully; steer as best as you can to a safe place, like a parking lot, the curb of a side street, or the shoulder of a highway. Turn on your hazard lights, and call an auto repair facility or tow truck for assistance. If the system hasn't failed completely, but you notice a decline in the power assist, check the power steering fluid reservoir and add more liquid as necessary. Make an appointment to have the lines checked for leaks.
