As a vehicle owner, it’s good to learn about and understand some of the services that your car will need during its lifetime. You’re probably already familiar with things like oil changes and AC service.

But, what about wheel alignments? Do you know the difference between front-end and 4-wheel alignments? When is it necessary to schedule service? What exactly does it entail? Here, we’ll try to answer some of the most commonly asked questions about wheel alignments.

What is a wheel alignment?

The term ‘wheel alignment’ is actually a little misleading. In reality, a wheel alignment involves making minor adjustments to a vehicle’s suspension, not the tires or wheels themselves. The main purpose is to ensure that the tires make proper contact with the road. Specifically, they need to be at the right angle in order to maximize road contact and provide appropriate traction and safe handling.

A wheel alignment generally involves looking at and making adjustments to three components:

Camber – This is the angle of the tire as seen from the front of the vehicle.
Toe – This is the angle of the tire as seen from above – a ‘bird’s eye view’.
Caster – Lastly, this is the angle of the steering axis.

An expert mechanic will evaluate all of these factors and make adjustments as necessary to bring your vehicle back into alignment.
