What is tracking / wheel alignment?
Tracking was born of a bygone era, when cars had no adjustment. Any measurement and adjustment was to be on the front wheels, for the ‘Toe’ angle only. Tracking on the front wheels also known as ‘two wheel alignment’ does not take in account the direction of the rear wheels are pointing. 2 wheel laser alignment is more commonly used on cars with solid back axels.

4 wheel digital alignment
A camera unit (sometimes called a “head”) is attached to a body that’s clamped on to the wheel. There are four camera units in a wheel alignment system (a camera unit for each wheel). The camera units communicate their positioning and send info back to the central computer which calculates the wheels position on each corner.
What we measure and adjust
• Toe measures how much a pair of wheels are turned in or out from a straight ahead position.
• Toe alignment can be carried out on the front wheels alone or the front and rear wheels.
• You will feel your car ‘pulling’ to one side if the toe alignment is out.
• Camber is the vertical tilt of the wheel in or out
• If the camber is out of alignment it will cause the tyre tread to wear excessively on the inside or outside edge
• If the camber is different from wheel to wheel it can cause your vehicle to pull to one side and become twitchy
• Camber misalignment may not be adjustable on all cars. If the camber alignment is out on these vehicles it may indicate that something is worn or bent and should be inspected more closely.
• Caster alignment is the angle of the steering pivot when viewed from the side of the vehicle
• Caster has little effect on tyre wear, but it affects steering stability
• If the caster is out of adjustment, it can cause problems in straight line tracking
• If the caster is equal but too negative, the steering will be light and the vehicle will wander
• If the caster is equal but too positive, the steering will be heavy and the steering wheel may kick when you hit a bump
Why set your wheel alignment?
Your tyres can last up to 12,000 miles longer when your vehicle is driving the same way it left the factory, If your vehicles tracking is out 3mm on the left for every straight mile you drive your vehicle will pull 9 feet to the left. Your vehicle will also drive and handle a hole lot better with having the tyre in full contact with the road and will increase fuel economy, it will also put less stress on other suspension components.
You won’t be able to visually check that your alignment is out but there are signs you can look out for
• Steering wheel not centralised
• Wear on the shoulder of the tyre
• Twitching when off and on the accelerator
• Steering wheel not returning correctly
• Car pulling to one side
