Few things worry drivers more than feeling their car shakes when driving. Sometimes it’s just a small vibration at certain speeds. Other times it’s a strong shake you feel through the steering wheel, seat, or even the whole car. Either way, it’s a sign something isn’t right.
If it’s specifically your steering wheel shaking rather than the whole car, that’s usually a wheel balance or alignment issue, more on that below.
At Coastwide Service Centre in Molendinar on the Gold Coast, we often get calls from people saying, “My car shakes when driving, can you check it out?” The good news is that most causes are fixable, but it’s important to find the problem early before it gets worse.
We’ll explain why your car shakes when driving, what the different vibrations mean, and what you should do if it happens.
Why it’s important not to ignore shaking
A car should feel smooth on the road. If your car shakes when driving, something is off balance, loose, or wearing out. Ignoring it can lead to:
-
Unsafe driving: vibration can affect steering and braking.
-
Faster wear on tyres, suspension and other parts.
-
Bigger repair bills later.
Catching the problem early keeps you safer and saves money.
Common causes when your car shakes when driving
There isn’t one single reason why a car shakes when driving. Here are the most common issues we see at Coastwide Service Centre:
1. Wheel balance issues
If your car shakes when driving at higher speeds (usually 80-110 km/h), it’s often a wheel balance problem. Small weights are used to balance tyres. If one comes off, the wheel can wobble.
2. Tyre problems
Tyres cause a lot of vibration issues:
-
Tyres out of round (common on older tyres).
-
Bulges or flat spots.
If your car shakes when driving and it’s worse on rough roads, tyres are a likely cause.
3. Wheel alignment
Poor alignment makes your steering pull and can cause shaking, especially if the car shakes when driving after hitting a pothole or kerb.
4. Suspension wear
Shocks, struts, and bushings keep the ride smooth. Worn suspension can make your car shakes when driving over bumps or feel loose in corners.
5. Brake issues
If your car shakes when driving and especially when braking, warped brake rotors may be the issue. You’ll feel it through the steering wheel when you slow down.
6. Engine or transmission mounts
If your car shakes when driving and also when stopped, worn engine or transmission mounts could be to blame. They hold the engine steady. When they fail, vibrations reach the cabin.
7. Driveshaft or CV joints
On rear-wheel or all-wheel drive cars, a bent driveshaft or bad universal joint can cause your car shakes when driving at all speeds. On front-wheel drive cars, worn CV joints can cause shuddering when accelerating.
8. Wheel bearings
A failing wheel bearing can cause vibration, humming noises and make your car shakes when driving worse the faster you go.
9. Engine misfire
If your engine is running rough, you might feel shaking especially under load or at idle. This is less about the wheels and more about the engine not firing smoothly.
How to describe the shaking
When you bring your car to a mechanic, describing exactly how the car shakes when driving helps us diagnose faster. Note:
-
Speed: Does it happen at 60 km/h? Only at highway speed?
-
Braking: Does it shake when you hit the brakes?
-
Steering: Does the steering wheel vibrate or the whole car?
-
Acceleration: Is it worse when speeding up or going uphill?
-
Surfaces: Smooth highway or rough roads?
This info can save time and cost when diagnosing why your car shakes when driving.
What to do if your car shakes when driving
-
Check tyre pressure, low or uneven pressure can cause vibration.
-
Inspect tyres for damage: bulges, flat spots, or uneven wear.
-
If your car shakes when driving badly at high speed, reduce speed and get to a safe place.
-
Visit a mechanic like Coastwide Service Centre for a proper inspection.
If the shaking is sudden, severe, or paired with steering or brake issues, it’s safest to pull over and call for help.
Diagnosing the problem professionally
At Coastwide Service Centre, we use several checks to find out why your car shakes when driving:
-
Wheel balance check.
-
Tyre inspection for wear or damage.
-
Wheel alignment testing.
-
Brake rotor thickness and run-out measurement.
-
Suspension and steering checks.
-
Driveshaft, CV joint, and bearing inspection.
-
Engine and mount testing if vibration is also at idle.
Our goal is to find the exact cause and fix it properly, not just guess.
Costs to fix car shaking
How much it costs depends on the cause:
-
Wheel balance: usually inexpensive.
-
Tyre replacement: moderate if needed.
-
Wheel alignment: affordable and often worth doing.
-
Brake rotor machining or replacement: mid-range.
-
Suspension repairs: varies depending on parts.
-
Engine mounts or driveline: more expensive but necessary for safety.
Catching the issue early usually means a cheaper repair.
Driving with a shaking car, is it safe?
If your car shakes when driving, it might still move, but safety is the concern:
-
If it’s mild and only at certain speeds, it’s less urgent but should still be checked soon.
-
If the shaking is strong, gets worse quickly, or comes with noise, steering pull or brake problems, stop driving and get it looked at right away.
Vibration can mean something is loose or failing, and continuing to drive can make it worse or cause a breakdown.
Why car shakes when driving on the Gold Coast
Our roads can be rough in places, with potholes, uneven surfaces and long highway runs. Beach sand and salt can also damage suspension and wheels over time. We see many cases of car shakes when driving caused by:
-
Tyres wearing unevenly from rough roads.
-
Wheels knocked out of alignment by potholes or kerbs.
-
Suspension rust or wear from salty air near the beach.
Regular servicing helps catch these issues early.
How to prevent shaking
Good habits reduce the risk that your car shakes when driving:
-
Rotate and balance tyres every 10,000 km.
-
Get wheel alignment checked yearly or after big pothole hits.
-
Keep tyres properly inflated.
-
Replace worn suspension parts before they fail.
-
Service brakes and have rotors machined or replaced if needed.
-
Regularly inspect for leaks or damage under the car.
Preventative care is cheaper than major repairs later.
Why early checks save money
Many people wait until shaking gets bad. But small problems like wheel balance or tyre wear are cheap to fix. Waiting until your car shakes when driving violently can mean damaged suspension, bearings, or steering, much more expensive repairs.
Car shaking while braking
If your car shakes when driving but especially when braking, it’s often warped brake rotors. You’ll feel it through the steering wheel or the whole car. It’s common after long downhill braking or towing. Machining or replacing rotors usually fixes it.
Car shaking when accelerating
If your car shakes when driving mainly when you accelerate, it could be:
-
Worn CV joints on a front-wheel drive car.
-
Failing driveshaft on a rear-wheel drive.
-
Engine mount problems.
-
Tyres slipping or uneven.
This type of shake often needs professional inspection.
Car shaking at high speed
A common complaint is car shakes when driving over 90 or 100 km/h. This usually points to wheel balance, tyre wear, or alignment. Sometimes it’s as simple as balancing wheels, but if ignored it can cause uneven tyre wear and more vibration.
Car shaking at low speed
If your car shakes when driving slowly, especially under 40 km/h, it’s more likely tyres with a flat spot, bad engine mounts, or a misfire. Low speed shake is less common for balance issues.
