Park the vehicle with the front wheels on the turntables (set to zero). Point the wheels straight ahead. An absolutely flat surface is needed for accurate measurement.
2
Attach the gauge to the right front wheel hub. Turn the steering wheel 20 degrees right. Level the gauge and set it to 0 degrees.

Caster Theory in design of Smart Vehicles. Introducing the screw theory, I have presented the required equations to calculate the camber angle based on caster and lean angles of a steerable wheel as a function of steer angle. So, we are able to design a smart vehicle to control the lateral force by varying the caster angle, independent of the input steer angle by the driver. The method can be used to increase safety of street cars, and maximize the cornering response of sport cars.

The above responses are basically correct, but the terminology is a bit mixed up. Here's a diagram which will help:
Of course, trail isn't the only thing to consider. Steering characteristics are much more nuanced. For instance, a road bike with a 72* head angle and 50mm of fork rake has the same trail as a track bike with a 75* angle and 32mm of rake, but obviously will handle very differently.
2010/12/17(金) 午前 4:59返信する
But for us regular folks, trail is the thing we can wrap our pea-brains around, and is in fact the dominant factor affecting at least straight line stability.
Beyond that the math gets kind of sticky. (BTW I used the kreuzotter site to come up with my example. Pretty slick calculator.)
I should come up with a signature line.

Steering Geometry
The idea of steering the front wheels around separate axes was invented in 1817 by a Munich carriage builder named Lankensperger. His agent, a fellow by the name of Rudolph Ackerman, took out an English patent on the invention. Later in 1878, a French carriage builder, Charles Jeantaud, introduced a refinement known as the "Jeantaud Diagram" which provided a more precise prediction of the correct geometry.

方位角(ほういかく、英: azimuth)とは、ある方向と基準となる方向との間の角の角度で、方向を数値で表す場合の水平成分である。
右手系では東を基準方位とし反時計回りを正の角度とする.左手系では北を基準方位とし時計回りを正の角度とする.また南を基準方位とする左手系の定義例も僅かに存在する. この左手系の使用は測量や航法などの分野に限れば標準的だが、一般的には(すなわち他の多くの分野においては)非推奨とされている。 経度・緯度の順序についても似た事情が存在する.
角度の単位は,測量や航法などの分野においては標準的には度・分・秒が用いられる.

they tell your how much error your wheel has, but not the actual wheel alignment. When you consider most tyres places will do a wheel alignment 'check' for free, I think they're expensive really, and the Minispares tracking gauge is probably a more useful tool for the money.

It doe`s not display degrees of toe in or out?
it only displays the error in toe in/toe out, Which is what it says in Gunsons own literature.
so you would have to check it, jack the car, adjust the tracking a little, then drive over it again, and then jack it and adjust the tracking again....
and as i said Kwik-fit etc 'check' your tracking for free anyway. they only charge to actually adjust it.

Wheel alignment technology advances continuously with the introduction of new makes and models of vehicles. Two wheel alignment is quickly becoming obsolete and four wheel alignment is rapidly being incorporated on many of the new models.
2011/1/7(金) 午前 7:01返信する
With the technology being incorporated in the newer vehicles, it's not just the front tires which steer the vehicle. Some manufacturers now use four wheel steering and complex electronic suspensions. Specific procedures must be followed to ensure proper wheel alignment.
2011/1/7(金) 午前 7:02返信する
With today's computerized vehicle systems, improperly aligned wheels can effect engine performance, ride, tire wear, steering and premature component failure.
Wheel alignment is the proper adjustment of ALL the interrelated suspension angles. In alignment terminology, these adjustment angles are called caster, camber, toe-in, steering axis inclination (SAI), vehicle ride height and toe-out on turns.

Camber: the inward or outward tilt of the wheel measured from top to bottom. Camber is adjusted to prevent excessive tire wear and to enhance straight ahead stability. It is measured in degrees and has several methods of adjustment.
2011/1/7(金) 午前 7:04返信する
Toe: is the difference in the distance measured on any axle between the leading edges and trailing edges of the wheel and tire assemblies at spindle height. This is the most critical tire wearing angle. The angle formed by a horizontal line through the plane of one wheel versus a centerline is called the individual toe.
2011/1/7(金) 午前 7:05返信する
Individual Toe: When a horizontal line is drawn through the plane of each wheel, and they intersect in front of the wheels, this is called toe-in or positive (+0 toe. When they intersect behind the wheels, this is called toe-out, or negative (-) toe.

Caster: forward or rearward tilt of the steering knuckle pivot points, is also called the steering axis. Caster is measured in degrees, from the steering axis to vertical, as viewed from the side. It is computed in degrees by looking at the camber change of each wheel through a specified steer. There are three types of caster settings.
2011/1/7(金) 午前 7:07返信する
Positive caster angle is when the top of the steering axis it tilted rearward. Negative caster angle is when the top of the steering axis is tilted forward. Negative caster can cause difficulty in returning out of a turn and wandering & weaving at high speeds. If the vehicle has unequal caster, it can cause the vehicle to pull from side to side. And zero degree caster is when the top of the steering axis is exactly vertical.

Set-Back: Front wheel set-back is the angle formed between the geometric centerline and a line perpendicular to the front axle. It is measured in degrees. Excessive set-back is normally created by frame or chassis errors. These errors are brought about in most cases by front end collision and in some cases by a manufacturing tolerance error. On cars designed with engine cradles, the cradle placement will affect set-back. If the cradle isn't square with the chassis, it must be straightened.
2011/1/7(金) 午前 7:08返信する
Set-back, if extreme, could bring about adverse handling effects, along with incorrect alignment measurement if overlooked. This may cause the vehicle to lead to the side where set-back exists; also a pull during braking can occur. On FWD vehicles it can also cause increased torque steer.
2011/1/7(金) 午前 7:09返信する
Thrust Angle: is the angle formed by the thrust line and the geometric centerline. The geometric centerline is a line drawn between the mid-point of the front axle and the mid-point of the rear axle.
When toe is off on either of the rear wheels, it creates a thrust angle that causes rear axle steer. The thrust line dictates the position of the front wheels when driving straight ahead. It is therefore the most accurate reference when measuring or adjusting the front wheels.

Inspection of the tires can help in diagnosing some wheel alignment failures. The tire wear patterns associated with improper alignment include single shoulder wear, cupping and feather edging.

Proper tire pressure is essential along with proper wheel alignment for extended tire wear. The correct pressure not only allows tires to perform at the standard for which they were designed, but is directly related to ride height. Remember that cold tires will register a slightly lower pressure than tires that are warm for usage. Tires with low pressure will wear both outer edges. Over inflation will wear the center of the tires.
