Squeaking noises can be tricky to pin down, but they're always worth acting on quickly, since ignoring one could put your safety and your bank balance at risk.
Key takeaways
- The most common causes of car squeaking are worn brake pads, a slipping belt, power steering issues, worn suspension components, or a worn wheel bearing
- Wheel squeaking when driving is often down to a worn wheel bearing: a high-pitched squeal that gets louder with speed, not tied to braking or turning
- Car creaking when driving isn't the same as squeaking. Creaking usually points to worn bushings, chassis components, or interior trim
- Some squeaking is minor and easy to fix. Others, particularly wheel bearing or brake pad wear, can be safety-critical if left unaddressed
- If in doubt, get a mechanic to investigate rather than waiting for the noise to get worse
Why is my car squeaking?
A squeaky car is never fun. But that noise isn't random, it's your car telling you something's up. Don't ignore it. The first move is working out exactly when it happens. Is it only when you brake? Only when you turn?
Common culprits for car squeaks include:
- Brake parts need replacing
- A drive belt problem
- Power steering issues
- A failing cambelt or water pump pulley
- Low fluid or a dry component
- Suspension trouble
- A worn wheel bearing issue
The more detail you can give a mechanic about when and where it squeaks, the faster they'll find it. Faster diagnosis usually means a smaller bill, so a bit of detective work now can save you money later.
"Wheel bearing noise is one you shouldn't put off. Unlike a squeaky belt, a failing bearing can eventually affect your steering and wheel stability, making it one of the more safety-critical causes on this list." What our motor insurance expert says
What does a high-pitched squeaky sound mean?
A high-pitched squeak isn't one thing, it's a symptom with a few different suspects. So pay attention to what triggers it:
- Squeak on ignition? That's often one of two belts: the auxiliary belt or the V-belt. Older cars tend to run V-belts, while most modern cars have swapped to the longer auxiliary-style belt.
- Squeak on the brakes? Worn brake pads are the usual answer.
Squeak from underneath as you drive? That's often the suspension, wearing in exactly the way the suspension is built to wear, just louder than it should.
Squeaking when turning the steering wheel
Turning the wheel and hearing a squeak points to the power steering. A few reasons this happens:
-
The power steering fluid is running low and needs topping up
-
The wheel housing is colliding with another component
-
A component of the steering system needs lubrication
-
The power steering fluid is contaminated and needs replacing
-
There is a power steering pump failure
Start simple: check the fluid level. If that's not it, find and compare a garage rather than guessing further.
Car squeaking when accelerating or slowing down: What could it be?
Squeak as you accelerate or slow down? A worn drive belt is a common cause, so it's worth a quick check for cracks or holes.
But the same noise at low speed could just as easily be your brakes trying to get your attention.
There's a third suspect worth knowing about: a worn wheel bearing, and it's behind a lot of wheel squeaking when driving. The giveaway is a high-pitched squeal that gets louder the faster you go, whether or not you're braking or turning.
Left alone, it doesn't just get noisier, it gets worse. The sound can deepen into a hum or a growl, and the wear behind it can start to affect your steering control and wheel stability.
That's not something to leave for another weekend, and it's not a fix you can do yourself in a car park either. Get a professional mechanic to take a look.
While you're getting that looked at, it's worth checking your tyre pressure and tread depth too, since uneven wear there can sometimes point to the same underlying issue.
Why does my car squeak when I brake?
Screech or squeak when you brake? That's your braking system flagging something.
A few elements could be behind it:
- Brake pads: these wear over time and eventually need replacing. They're doing the actual work of stopping your car, so this one matters.
- Brake rotors: the discs your brake pads grip onto. They work as a pair with the pads, so if one needs replacing, expect the other to follow soon after.
- Brake callipers: these squeeze the pads against the rotors. Without them working properly, the pads and rotors can't do their job either.
Modern cars often flag brake issues on the dashboard too, so keep an eye out there as well as an ear out on the road.
Squeaky suspension: What it means and how to fix it
Your suspension takes the hit, literally, every time you go over a bump or pothole. That constant work means it wears over time, and squeaking is often the first sign.
Sometimes it's simple: a bit of lubrication sorts it. Other times, it means a spring or shock absorber needs replacing.
One thing worth knowing: car creaking when driving isn't the same as car squeaking. A creak tends to come from worn bushings, chassis components, or interior trim flexing, rather than the suspension causes above.
Listen carefully before you assume it's your suspension doing the talking.
Is it safe or dangerous to drive a squeaky car?
Don't panic at the first squeaking noise while driving, but don't ignore it either. Sometimes it's as simple as low power steering fluid. Other times, it's a genuine safety issue.
The honest answer is: it depends on the cause, and you won't always know which one you've got just by listening. So track down where the noise is coming from, and if it persists, get a professional mechanic to take a proper look.
How to prevent your car from squeaking
Start with your fluids. It takes a bit of time, but keeping these topped up matters:
-
Engine oil
-
Power steering fluid
-
Brake fluid
-
Clutch fluid
Your car's manual will tell you exactly how. And if any of these have picked up debris, give the affected tank a proper clean rather than just topping up on top of it.
Beyond fluids, keeping key components lubricated goes a long way. So does regular servicing. No part of your car lasts forever, and staying ahead of wear is cheaper than catching up on it.
As a rough guide: drive belts often need replacing somewhere between 60,000 and 100,000 miles, and brake pads somewhere between 20,000 and 70,000 miles, depending on how you drive.
Check your manual for the specifics that apply to your car.
Will a squeaking noise affect my insurance?
It depends. Your car needs to meet the legal requirements set out in our guide to car insurance, tax and MOT rules. Fall short of these, and you risk invalidating your cover if you have an accident.
One thing insurance won't do: pay to fix the squeak itself. Maintenance repairs generally sit outside what standard car insurance covers, so this one's on you to sort and pay for.
There's more at stake than just the repair bill, too. Driving in a dangerous condition can land you:
- Penalty points on your licence
- Fines up to £2,500
- A driving ban
And if any of that happens, expect your insurance renewal price to reflect it.
