Power steering makes driving much easier by allowing you to turn the wheel with minimal effort. But like any other system in your car, power steering components wear out over time—especially the power steering pump. When the pump starts failing, you will notice warning signs that indicate trouble ahead. Catching the problem early can prevent complete steering failure and costly repairs.
What Does the Power Steering Pump Do
The power steering pump plays a crucial role in assisting with steering by using hydraulic pressure to make turning the wheel easier. It circulates power steering fluid through the system, ensuring that your steering responds smoothly when you turn. If the pump begins to fail, you may experience increased steering effort, noises, or even a complete loss of power assist.
Signs Your Power Steering Pump Is Failing
1. Whining or Groaning Noises When Turning
One of the first signs of a failing power steering pump is a whining, groaning, or squealing noise when you turn the steering wheel. This usually happens because the pump is struggling to move fluid properly. Low power steering fluid levels or air bubbles in the system can also cause this noise, so checking your fluid is a good first step.
2. Stiff or Difficult Steering
If turning the wheel requires more effort than usual, your power steering pump may not be generating enough hydraulic pressure. This issue can make maneuvering at low speeds—such as parking—much more challenging. In severe cases, you may even lose power steering assist entirely, making the car difficult and unsafe to drive.
3. Fluid Leaks Under the Car
Power steering fluid leaks are a common sign of pump failure. If you notice a reddish or amber-colored puddle under your car, the pump or one of the hoses may be leaking. Low fluid levels can lead to damage throughout the power steering system, so it’s important to address leaks as soon as possible.
4. Steering Wheel Jerks or Feels Unstable
A failing power steering pump can cause inconsistent pressure in the system, making your steering feel unpredictable. You might notice the wheel suddenly becoming stiff, then loosening up again. If the steering response feels uneven, the pump may not be delivering a steady flow of fluid.
5. Burning Smell or Smoke from the Engine Bay
A worn-out power steering pump can overheat, leading to a burning smell or even smoke coming from under the hood. This often happens if the pump is working harder than normal due to low fluid or internal damage. If you experience this issue, turn off your car and have it inspected immediately to avoid further damage.
What Causes a Power Steering Pump to Fail
Power steering pumps don’t last forever, but certain factors can make them wear out faster:
- Low fluid levels – Running the system without enough fluid can cause internal damage.
- Contaminated fluid – Dirt, debris, or moisture in the fluid can wear down pump components.
- Worn-out drive belt – If the belt that powers the pump is loose or damaged, the pump won’t function properly.
- Age and wear – Over time, seals and internal parts break down, leading to reduced performance.
Can You Drive with a Bad Power Steering Pump
Technically, yes—but it’s not a good idea. If your power steering pump is failing, turning the wheel will become increasingly difficult, making driving unsafe—especially in tight spaces or emergencies. Ignoring the problem can also lead to further damage to the steering system, resulting in even more expensive repairs.
