A vibration through the steering wheel is unsettling and easy to ignore once you get used to it. But it usually means a component is out of balance, worn, or damaged.
When the vibration happens is the best clue to its cause.
Vibration at certain speeds
Shaking that appears around 80 to 110 km/h (50 to 70 mph) and fades above or below is classically caused by an unbalanced wheel. A wheel weight may have fallen off. Balancing is quick and cheap at a tyre shop.
Vibration under braking
A pulsing or shuddering through the wheel and brake pedal when you brake usually points to warped or unevenly worn brake discs (rotors). They may need skimming or replacing, usually with new pads.
Vibration all the time
- ▸A damaged tyre with a bulge or separated tread
- ▸A bent wheel from a pothole
- ▸Worn wheel bearings — often with a humming that rises with speed
- ▸Worn steering or suspension joints
- ▸Loose wheel nuts — stop and check immediately if a wheel was recently changed
Vibration at idle
If the car shakes when stationary, the problem is more likely in the engine: worn engine mounts, a misfire, or rough idle. A flashing check engine light alongside shaking means a serious misfire — reduce speed and get it checked.
Do a quick tyre check
Look at each tyre for bulges, cuts, and uneven wear, and check the rims for dents. A bulge in the sidewall means the tyre structure is damaged and it should be replaced before you drive any distance.
