Is your car pulling one way or another when you’re driving? Do you feel an unusual or harsh vibration? Are your tires wearing unevenly? If so, your car may be out of alignment.
Alignment relates to the suspension of your car. Your suspension determines how tires come in contact with the road. Often people assume alignment is directly related to the tires, as this is where you feel bad alignment when you’re driving. But think of it like this: if you are skiing and your skis are pointed inward, sideways, or spreading wide, the skis are not broken; rather, it’s your legs and knees, your shocks or struts, throwing everything off.
Three terms to know when talking alignment
When it comes to alignment there are three things to keep in mind: toe, camber and caster. Each of these terms defines a different way in which the tires can be out of alignment. Let’s keep our skis on and carve further into each term.
Toe is simple if you’re looking down at your skis. There is toe in, and toe out. Like your feet, the tires can be slightly pointed toward or away from one another. Toe in will wear the tires on the outside and toe out on the inside. Think about skiing with your toes pointed toward one another: snow will build up on the outside as the skis scrape, which is similar to how a tire might wear on the outside.
Now, still on your skis, gently cruising down the mountain, try to touch your knees together. This is like having negative camber, as everything is folded in and the top of the tires point toward one another. If the camber of your car is off, it will cause tires to wear oddly and affect how the car handles.
Some finely-tuned sports cars use negative camber to improve handling. But if you’re driving to and from soccer practice, you don’t need to hug the neighborhood curves.
Caster relates to the vertical angle of your suspension. A positive caster angle means the top of the suspension is back, and negative is when the top of the suspension is tilted forward. This affects how your car performs and handles. If the caster is off, it’s like your skis have drifted out in front of your torso and now you’re leaning back while moving forward. This is not an efficient way to get down the mountain and it is equally troublesome for a car. When the caster is off your car may act irregularly at higher speeds — exactly when you need it to drive true.
