Car noises and vibrations: finding the cause
Inspection for knocks, vibrations or unusual sounds. Tell us when they occur and which part of the car they seem to come from.
A new noise is your car asking for attention. Tell us when it happens: when braking, turning, over bumps or at a certain speed. That alone often points to the cause.
Typical sources
- Squeal when braking: pads or discs
- Knock over bumps: suspension joints and bushes
- Hum that grows with speed: wheel bearings or tyres
- Vibration at speed: wheel balance or driveshafts
How we find it
We listen for the noise on a road test, then inspect the car on the lift and confirm the source before replacing parts.
Questions and answers
Why does the car vibrate at highway speed?
Most often the wheels need balancing or a tyre is damaged. Worn driveshafts or engine mounts are other causes.
What does a knock over bumps mean?
Usually worn suspension parts, such as drop links, bushes or shock absorber mounts.
