The steering wheel is the part you touch every moment, and it can reveal a surprising amount about the car’s condition.
1. Vibration at speed
Shaking through the wheel at a particular speed usually means wheel balance or a buckled rim. Vibration under braking points to warped discs.
2. Pulling to one side
Persistent pull means misalignment, uneven tyre pressures or a sticking caliper.
3. Play in the wheel
A dead zone before the car steers indicates wear in the steering rack or track rod ends and should be investigated promptly.
4. Heavy steering
A sudden increase in effort suggests low power-steering fluid or a failing pump.
