Wheel alignment (sometimes referred to as tracking) is a service that involves correcting the angles of your wheels so that they are accurately re-set to the original manufacturer's specification. You may need to have your wheels aligned if your car has recently had knock or impact, such as going through a deep pothole.
Signs of misaligned wheels
Chances are that you won’t be able to see whether your wheels are misaligned just from looking at the steering and suspension components, but there are a few signs you can look out for if you suspect your tracking is off:
Vehicle pulling to one side
Reduced fuel economy
Uneven tyre wear
Increased wear on suspension components
