6 Signs Of A Bad Or Failing Power Steering Pump
Power steering has been a staple on vehicles since the 1950s. Today, few people would know how to drive without this steering support. Yet, when the power steering pump starts to fail, they get a little taste of what it might be like. To prevent driving problems, it’s best to know the most common bad power steering pump symptoms.
We review what’s most likely to happen when the power steering pump fails and show you the function of this vital part. We also give you the location of it, so you can test it and we answer your most important questions. Finally, we will tell you the approximate cost for repairs in case you need to have your power steering pump replaced.
Common Symptoms of a Failing Power Steering Pump
When the power steering pump starts to fail, you will feel a heavy or stiff wheel, as well as have a struggle with rough or jerky steering. It can also cause a squealing or knocking noise, an illuminated power steering warning on the dash, or you may notice metal flakes in the fluid. Let’s take a look at these symptoms a little closer.
1. Heavy or Stiff Steering
When the power steering pump fails, the car starts to feel like it has a manual steering system. The wheel gets difficult to turn, almost as if you need to be a bodybuilder in order to control the vehicle. Because the pump is needed to circulate the fluid, there won’t be enough pressure throughout the system to make minor adjustments.
2. Squealing Noises When Turning
As the power steering pump begins to fade, you may hear some strange noises. Squealing or whining is often the most complained about, and it becomes more noticeable while turning the steering wheel. You may also notice the sound when you first crank the engine on. As the RPMs climb, the pitch of the sound can also change.
3. Rough/Jerky Steering
If you still have control over the steering but notice it is not acting normally, the pump could be going bad. The steering can often become jerky or rough as the pump fails, making it more difficult to keep the vehicle in the lane where it belongs. This is a safety concern that should be dealt with immediately.
4. Knocking Noises
Once the sound becomes a groaning or knocking, you know you need to check the system immediately. A defective power steering pump could lead to this problem. Otherwise, there could be other issues that need to be repaired.
5. Metal Flakes In The Power Steering Fluid Reservoir
When the pump becomes damaged, metal pieces from it can come apart and mix into the power steering fluid. These shards of metal can damage the passages to the power steering system, leading to even more complications. Not only will the pump need to be replaced, but the steering gear may become damaged, and you will need to perform a system flush too.
6. Power Steering Symbol On The Dashboard
Among the dashboard warning lights, you may notice the power steering symbol. This light typically has a steering wheel symbol with an exclamation mark. Not all cars have this light, so you can’t rely on it to tell you if something has failed. As with all warning lights, this indicator is trying to get your attention.
