- Wheel balance or bent rim
- Brake disc run-out
- Worn engine mounts
- CV joint or driveshaft
- Tire wear
Checks to run

- Balance and inspect the wheels
- Check discs and mounts
Tools you may need

Confirm before replacing. These are hypotheses to check — never buy parts on a guess. If the fault involves brakes, airbags or fuel under pressure, use a professional.
