In its most basic form, a wheel alignment consists of adjusting the angles of the wheels so that they are perpendicular to the ground and parallel to each other. The purpose of these adjustments is maximum tire life and a vehicle that tracks straight and true when driving along a straight and level road.This article begins with information that any motorist should know; however, if you are interested in learning more about this topic. We will cover various levels of detail with the levels containing information that even a wheel alignment technician will find informative. Wheel Alignment is often confused with Wheel Balancing. The two really have nothing to do with each other except for the fact that they affect ride and handling.
If a wheel is out ofbalance, it will cause a vibration at highway speeds that can be felt in the steering wheel and/or the seat.
If the alignment is out, it can cause excessive tire wear and steering or tracking problems. & For more information on Wheel Balancing,Ifyou know anything about wheel alignment, you've probably heard the terms Camber, Caster and Toe-in.CamberCamber is the angle of the wheel,measured in degrees, when viewed from the front of the vehicle.
If the top of the wheel is leaning out from the center of the car, then the camber is positive,if it's leaning in, then the camber is negative.If the camber is out of adjustment, it will cause tire wear on one side of the tire's tread. If the camber is too far negative, for instance, then the tire will wear on the inside of the tread.
When you turn the steering wheel, the front wheels respond by turning on a pivot attached to the suspension system. Caster is the angle of this steering pivot, measured in degrees, when viewed from the side of the vehicle. If the top of the pivot is leaning toward the rear of the car, then the caster is positive, if it is leaning toward the front, it is negative. If the caster is out of adjustment, it can cause problems in straight line tracking. If the caster is different from side to side, the vehicle will pull to the side with the less positive caster. If the caster is equal but too negative, the steering will be light and the vehicle will wander and be difficult to keep in a straight line. If the caster is equal but too positive, the steering will be heavy and the steering wheel may kick when you hit a bump. Caster has little affect on tire wear.The best way to visualize caster is to picture a
shopping cart caster.
measurement is the difference in the distance between the front of the tires and the back of the tires. It is measured in fractions of an inch in the US and is usually set close to zero which means that the wheels are parallel with each other.Toe-in means that the fronts of the tires are closer to each other than the rears.is just the opposite. An incorrect toe-in will cause rapid tire wear to both tires equally. This type of tire wear is called a saw-tooth wear pattern as shown in this illustration.
The pivot of this type of caster, while not at an angle,intersects the ground ahead of the wheel contact patch. When the wheel is behind the pivot at the point where it contacts the ground, it is in positive caster. Picture yourself trying to push the cart and keep the wheel ahead of the pivot. The wheel will continually try to turn from straight ahead. That is what happens when a car has the caster set too far negative. Like camber, on many front-wheel-drive vehicles, caster is not adjustable. If the caster is outon these cars, it indicates that something is worn or bent, possibly from an accident, and must be repaired or replaced.The Toe
