Causes Of Power Steering Pump Noises From North Texas Experts

| By: Christian Brothers Automotive Rufe Snow

In every hydraulic power steering system, there is a pump that provides pressure so the fluid can do its job. When there is a problem with the system, the pump emits an unmistakable sound as you drive. It’s a whining and whirring sound that varies in pitch based on your speed and how you attempt to steer your vehicle, and the noise is often worse in cold weather or right after you start your car. While the noise might soften after your car warms up, the power steering system is still in trouble. This unmistakable sound signals the eminent failure of your power steering pump unless it is taken care of quickly.

There are a few reasons that might cause your pump to start making this noise. Our ASE-certified technicians at Christian Brothers Automotive Rufe Snow can determine why your pump is having issues and how these problems can be taken care of at our auto repair shop.

Low power steering fluid

The most common cause of power steering noises coming from the pump is low power steering fluid level. A lot of drivers in North Richland Hills, Keller, and Watauga do not check the power steering fluid level or quality very frequently. Most people are blindsided by a loss of fluid. Most power steering fluid tanks do not hold much fluid, either. So, your power steering system's capabilities can be quickly affected even if you have only a small leak.

The fluid level can be easily accessed and checked under the hood of your car. Some tanks have a clear tank and a line to mark when the tank is considered full. Other fluid tanks may be opaque, but they usually have a dipstick to check the fluid level.

Failing power steering pump

A failing pump is also another cause of power steering noises. Leaking power steering fluid around the pulley or difficulty steering your car are good indicators of a failing pump. If your vehicle has multiple power steering symptoms, you should replace the pump before it gives out and leaves you stranded on the road.

Trapped air and pump design

If the pump impeller begins to catch air bubbles, unwanted noise and vibrations may occur. It can be difficult to diagnose air bubbles trapped inside the pump. We recommend a power steering fluid flush to drain the fluid and get rid of any air bubbles. Fresh fluid is then pumped back into the system to fill it to proper specifications.

Some power steering pumps may get noisy with age, but they can continue to work well enough. There are different kinds of power steering fluids for different systems. Sometimes simply using a different type of power steering fluid can help reduce the noise as well.
