What Is Power Steering and How Does It Work?
The power steering system in your car is designed to make steering easier by using hydraulic or electric assistance. When functioning properly, it reduces the effort required to turn the steering wheel, especially at low speeds or when parking. The system consists of a power steering pump, a steering rack or gearbox, and fluid that circulates through the system to maintain smooth movement. When something goes wrong, however, your steering may become stiff, difficult, or even impossible to control, which is both inconvenient and dangerous.

Common Signs of a Malfunctioning Power Steering System
Before diving into troubleshooting, it’s important to recognize the common signs of power steering issues. Understanding these symptoms can help you identify the problem quickly and prevent further damage to your vehicle:
1. Hard-to-Turn Steering Wheel
If you’re struggling to turn the steering wheel, especially at low speeds or when parked, it’s a clear sign that your power steering system isn’t working as it should. This issue is often caused by low power steering fluid levels or a failing power steering pump.
2. Whining or Groaning Noises
One of the most common signs of a malfunctioning power steering system is unusual noises. A whining, groaning, or squealing noise while turning the wheel may indicate a lack of power steering fluid or a problem with the power steering pump.
3. Fluid Leaks
If you notice a reddish-brown or clear fluid underneath your car, it’s likely power steering fluid leaking from the system. Leaking fluid can cause the system to lose pressure, which affects the functionality of your steering.
4. Steering Wheel Vibration
If the steering wheel vibrates when turning, it could be a sign of air trapped in the power steering system or a failing pump. This vibration might feel like a slight shaking or a more pronounced wobble.
5. Difficulty Parking
When power steering is not working properly, parking your car becomes a difficult and exhausting task. If you’re finding it unusually hard to turn the wheel while parking or at a standstill, the power steering system may be to blame.
How to Troubleshoot a Malfunctioning Power Steering System
Now that you know the common symptoms, it’s time to troubleshoot your car’s power steering system. Here are some practical steps you can take to identify the issue:
Step 1: Check the Power Steering Fluid Level
The first step in troubleshooting power steering problems is to check the fluid level. Low or empty fluid is one of the most common causes of steering issues. To check the fluid level:
- Locate the power steering fluid reservoir (refer to your car’s manual for its location).
- Check the fluid level by looking at the dipstick or the fluid indicator on the reservoir.
- If the fluid level is low, top it off with the manufacturer-recommended fluid.
If topping off the fluid resolves the issue, then low fluid was likely the cause. However, if the fluid level continues to drop, there may be a leak in the system that needs to be addressed.
Step 2: Inspect for Leaks
Power steering fluid leaks are common and can significantly impact the functionality of the system. If you’ve already topped off the fluid and the problem persists, check for any visible leaks around the power steering pump, hoses, or the steering rack. Leaks may appear as dark, oily spots on the ground beneath the car.
If you find a leak, it’s best to replace the damaged part, whether it’s a hose or the power steering pump itself. A professional mechanic can help if you’re unsure of the extent of the leak.
Step 3: Inspect the Power Steering Pump
The power steering pump is a vital component of the system. If it’s damaged or failing, the steering wheel can become hard to turn, and you may hear whining noises. To check the pump:
- Start the engine and turn the steering wheel from left to right.
- Listen for any whining or groaning noises that indicate a pump issue.
- Feel for any vibrations or changes in the steering response.
If the pump is the source of the problem, it may need to be repaired or replaced. A malfunctioning pump will require professional attention to avoid further damage to the system.
Step 4: Check for Air in the System
Air trapped in the power steering system can cause vibrations in the steering wheel and reduce steering assistance. To remove air from the system, you can try “bleeding” the power steering system. This involves turning the steering wheel from side to side with the engine running to release air bubbles from the system.
If the problem persists or if you’re unsure how to bleed the system, it’s best to have a mechanic perform this service.
Step 5: Evaluate the Steering Rack
The steering rack is responsible for translating the steering wheel's movement into actual wheel movement. If there is a problem with the rack, you may notice difficulty turning the wheel, fluid leaks, or steering vibrations. Unfortunately, issues with the steering rack are often difficult to repair on your own and may require the help of a professional mechanic.
When to Call for Professional Help or Towing
If you’ve followed the troubleshooting steps above and the problem persists, it may be time to seek professional help. Sometimes the issue is more complicated than low fluid or a minor leak, such as a failing pump or steering rack. Additionally, if you’re experiencing power steering failure while on the road, it’s unsafe to continue driving without addressing the problem.
