Why Power Steering Fails

If you’re like most drivers, you probably think of power steering as a key safety feature that ensures your car handles well in turns. But in fact, power steering failures are among the most common causes of accidents. In this article, we’ll explore the different types of power steering failures and how to prevent them.

What is a Power Steering System?

A power steering system is a hydraulic, gear-driven system that controls the movement of the steering wheel. It uses fluid pressure and mechanical linkages to move the steering rack and provide feedback to the driver.

The power steering system is responsible for providing accurate and consistent steering input, regardless of driving conditions or vehicle speed. When it fails, power steering can become difficult to use and can cause loss of control.

There are several common causes of power steering failure, including worn or damaged components, faulty fluid hoses and tubes, and failed pump seals. In some cases, a power steering system may not function at all. If you notice decreased performance or difficulty in using your power steering system, it’s important to take action to correct the problem.

Power Steering System Components:

-Steering Rack: The steering rack is a metal frame that houses the hydraulic components of the power steering system. The rack moves the wheel through a series of gears, providing the necessary input for accurate and consistent steering. Worn or damaged racks can cause loss of control and reduced performance.
\-Pump: The pump circulates fluid through the system and delivers pressurized

Common Types of Power Steering

There are three common types of power steering failures: failure of the power steering pump, failure of the power steering belt, and failure of the power steering pulley.

The power steering pump is a small, durable engine that helps direct the flow of fluid to and from the power steering system. If it fails, the power steering will become severely impaired. The most common cause of a power steering pump failure is overheating. Overheating can be caused by a number of factors, such as an oversize or undersized radiator, faulty thermostat, dirty air filter or clogged fluid lines.

The power steering belt is a thin rubber band that connects the power steering pump to the gearbox. If it breaks, the belt will slip and cause severe loss in torque and speed. The most common cause of a power steering belt failure is age – belts typically last around 10 years before they need to be replaced. Other causes include excessive wear due to heavy use or poor maintenance habits, as well as tensioning problems in the gearbox caused by incorrect oil level or incorrect assembly procedure.

The power steering pulley is located on the engine shaft and helps transfer energy from the motor to the gearbox.

How a Power Steering System Works

A power steering system helps a vehicle steer by providing a constant force to the steering wheel. The system uses a gearbox, pump, and reservoir to create a flow of fluid around the steering gear. This flow of fluid helps the driver steer the vehicle. A power steering system can fail for a variety of reasons, including worn or broken parts. If your power steering system is failing, you may need to replace it.

Causes of Power Steering Failures

Power steering is a system that helps the driver steer their vehicle. It consists of a motor, gearbox, and pump that help the driver turn the wheel by transferring power from the engine to the front wheels. Power steering can fail for many reasons, but the most common causes are:

-A lack of fluid in the system – The power steering fluid helps move the pump and motor, and if it’s not enough, it will cause problems. The fluid can be lost from many sources, including when it leaks from the joints between the pump and gearbox or from the reservoir. Check for leaks and replace any that are found.

-A worn or damaged gearbox – If the gearbox is worn out, it will not be able to transfer enough power to the pump and motor. This can cause them to overheat and fail. Check for wear and replace any parts that are needed.

-A broken or defective pump – If the pump is broken or defective, it won’t be able to move enough fluid to keep everything working properly. This can cause overheating and a failure. Check for damage and replace it if necessary.

How to Fix a Power Steering System

If you’re experiencing problems with your power steering, there are a few things you can do to fix the issue. In this article, we’ll go over some of the most common causes and solutions for power steering failure.


A power steering failure can be an extremely frustrating experience, especially if you are driving in a busy or crowded area. If you notice that your power steering is not performing as it should, don’t hesitate to take your vehicle into a shop for inspection. By doing so, you might be able to get your car back on the road in a timely manner and avoid any additional damage.
