In simple terms tracking is the adjustment of the tyres so that they are pointing in a forward direction. Tracking can be done on both the front and rear tyres.
.
Wheel Alignment - The front wheels are tracked to the rear. Only the front track rod ends are adjusted so that the tyres are pointing forwards at the appropriate angle.
Do you need to have your tracking adjusted?
Yes- if the tracking has been knocked out then there will be a negative effect on the car and your driving experience. Your steering wheel is no longer centred and to drive in a straight line it will be at an angle. Which way the steering leans, is an indication of which side the tracking is out. This will affect the handling of the car.
What are the symptoms of a poorly aligned car?
The steering is heavier than it should be. This is because the ball joints are under strain and the car geometry can’t self-centre. What does this mean? Think of the hip joint- that is a ball and socket joint. If your hip joint is causing your leg to turn inwards or outwards, then walking is more difficult. There is already strain on the joint – making walking and moving more difficult.
The car is pulling in a particular direction- the rear tyres are pulling the cars towards the thrust line. The thrust angle is the difference between the centre line of the car and the rear axle. If the tracking of the car is out, then the thrust angle will cause the car to pull towards the direction that the rear tyres are pointing in.
