Power steering has long been a standard feature in most vehicles on the road, so much so that we take it for granted and probably forget that it's even there.
That is, of course, until the power steering system stops working.
The most obvious sign of a problem is when the power steering light on your instrument panel lights up. You may also notice other clues, such as unusual noises, steering difficulties, and signs related to the power steering fluid like discolouring and metal shavings.
Sure, your car is still drivable without power steering, but it’ll be tough and possibly dangerous.
Now, if you’re looking for a bit of a reminder on what your power steering system is and how it works, our previous article dives deep into that side of the discussion that we won’t be covering here.
However, if you’re ready to see the list of 10 signs of power steering problems, let’s get to it.
What Are the Signs of Power Steering Problems?
Instrument Panel Indicator
The most telling signs of problems in a car come from the instrument panel or dashboard, and it’s not any different with power steering issues.
1. Power steering light turns on
So, the most apparent sign of a problem is when the power steering light on your instrument panel turns on. That’s your car’s way of telling you that there’s a problem with that system, even though it won’t be able to specify the exact problem.
Aside from that light as an indicator, you’ve also got nine other warning signs that fall into three categories: unusual noises, steering difficulties, and issues with the power steering fluid.
Let’s take a closer look at each one.
Unusual Noises
Cars make plenty of noises, and many of them are just part of their standard functioning. Sadly, some noises point to a problem, including issues with your power steering.
2. Whining, squealing, groaning when turning
When you suspect a problem with your power steering, take the car to a place where you can test it, like an empty parking lot. Then, turn the radio down and listen as you turn your vehicle to the left or the right.
Here, what you’re listening out for are sounds like whining, squealing, or groaning whenever you make those turns. If you hear any of them, that’s a sign of an issue with parts like the power steering pump.
3. Squealing when starting the car
Some of those noises don’t just happen when you’re making a turn. Another time to keep your ears open is when you start the car. Here, you’re trying to listen for a squealing sound, which suggests a problem with the power steering.
Steering Difficulties
As you can expect, there will be performance-related signs that your power steering system is acting up. In this case, the affected performance has less to do with speed than how your car turns.
Remember: when power steering is working as it should, you’ll be able to turn your steering wheel without much effort.
4. Difficulty turning the steering wheel
The first and most obvious sign of a problem is when you have difficulty turning the steering wheel. That’s because when your power steering stopped working suddenly, you were trying to turn that wheel through sheer physical force without the aid of power steering.
Again, you could keep driving your car in this condition. However, as you can imagine, your arms will get tired quickly since you’ll be doing all the turning without help.
5. Delayed response when turning wheel
In the previous point above, we saw what happens when the power steering stops working entirely. However, you might find that it still works in some cases, albeit in a delayed manner. You’ll notice this when you feel a delayed response as you turn the steering wheel.
6. Steering wheel shakes or pulses
Intermittent and unstable functioning of the power steering system is also another issue, and you’ll feel it as unusual shaking or pulsing of your steering wheel.
7. Steering wheel wanders
Lastly, you may notice your steering wheel wandering or drifting to one side as if it had a mind of its own. Although there are several possibilities for this, one of the most likely reason is a power steering problem.
Power Steering Fluid
When it comes to power steering problems, you’ll likely notice the weird sounds and unusual performance first. Still, another place you can check for a problem is the power steering fluid, which you can inspect the next time you take it for a top-up.
Here are the signs to look out for.
8. Unexpectedly low power steering fluid
Like any other fluid in your car, you’ll have to top it up from time to time. It’s completely normal to lose some fluids over an extended period.
However, if you find yourself having to top-up power steering fluid more often and in higher amounts than usual, then that’s a sign you’ve got a problem. Most likely, there’s a leak somewhere in your system.
9. Power steering fluid is grey
Power steering fluid discolouration is also another tell-tale sign. Typically, the fluid is red, but it’ll change to grey and black when the fluid has oxidized or if there are metal shavings inside it.
Whatever the case might be, you’ll want to change the fluid immediately and then troubleshoot for problems in the system.
10. Power steering fluid has metal shavings
Last but not least, the presence of metal shavings in your power steering fluid is a terrible sign. Metal shavings mean that two metal parts somewhere are grinding against each other even when they shouldn’t.
Frequently Asked Questions
1. What can cause power steering problems?
Power steering is a standard feature across car brands and models. As such, the problems and their causes are pretty much the same, too.
So, regardless of whether you’re having VE Commodore power steering problems or Ford Territory power steering problems, these causes will most likely be the same.
The most likely causes behind power steering problems are:
- Fluid contamination, such as by leaking coolant
- Lack of fluid, primarily if caused by a leak
- Worn or faulty pump that has experienced damage or extended wear and tear
2. Can I drive without power steering?
Yes, you can still drive your car even without functional power steering. Still, even though your car remains mobile, that doesn’t mean it’s a good idea.
For starters, you’ll get exhausted quickly from having to use physical strength to turn your steering wheel. Plus, it’s also dangerous because you won’t be able to react to dangers on the road as quickly as you would with power steering.
