Chapter 1 Introduction
1.1 Definition
3D series wheel alignment system is to test wheel parameters and provide reference of
manufacturer specs, by compare the two set of parameters, operator can adjust the
vehicle wheel parameters to reasonable range, make the vehicle wheels in good
condition and avoid unreasonable tire worn.
1.2 When wheel alignment will be needed
At the following circumstance, wheel alignment will be necessary:
Vehicle pull to one side when release steering wheel.
Uneven tire worn.
Steering wheel too heavy, too light or shake when driving at high speed.
After tire change, chassis parts replacement.
After collision.
After 3000 km’s drive of new car.
At regular vehicle maintenance.
1.3 Major alignment parameter
Wheel alignment angles are relative angle of the chassis parts, which makes the
vehicle running stable and reduce tire worn.
Major wheel alignment angle include: Camber, Toe, Caster, SAI, Toe-out on Turn.

GA-600S 3D Wheel Aligner User Manual

1. 3. 1 Camber
Camber is the leaning of the wheel inwards or outwards from the vertical. If the
road wheel leans outwards from the vertical, it has positive camber and when leaning
inwards from the vertical - negative camber, looking from the front or rear of the
vehicle. See Fig.1.1. Camber is measured in degrees. Without camber, the wheels
will tilt to the inside at full load; increase the possibility of uneven tire worn. Hence, this
parameter can extend the life of tire and related axis.
Figure 1.1 Figure 1. 2
1. 3. 2 Toe-in
The toe setting is the amount by which the front or rear wheels point inwards or
outwards at the front of the wheel in relation to each other (see Fig.1.2). When the
wheels point inwards they are said to toe-in. Toe-in figures are given a positive value.
Conversely when the wheels point outwards they are toe-out and the figures are shown
as a negative value.
The purpose of correct toe is to ensure that the wheels run parallel when the vehicle is
driving. An incorrect toe setting may affect the stability and controllability of the
vehicle.

GA-600S 3D Wheel Aligner User Manual
1-3
1. 3. 3 Steering Axle Inclination
Steering Axle Inclination (SAI) is the angle of steering axis and vertical line (vehicle
front view). As show in Figure 1.3. Correct Kingpin Inclination can equalize the loads
applied on bearings so that the life of bearings can be prolonged and the controllability
of steering is improved. Without the inclination, the controllability of the steering may
be affected; further more, the vehicle weight and the ground counterforce may cause
significant stress in the axle and finally damage the axle. Correct inclination of king pin
is also helpful for the vehicle to restore its straight-ahead position after steering.
Kingpin Inclination is determined when the vehicle suspension is designed. It is not
service adjustable.
Figure 1. 3 Figure 1. 4
1. 3. 4 Caster
Caster is the tilting of the kingpin either forwards or backwards from vertical, as viewed
from side of the vehicle. See Figure 1. 4. When the king pin is tilted backwards from the
vertical, caster is positive. When the king pin is tilted forwards, caster is negative.
Caster angle influences the directional stability of the steering. To increase the
tendency of the steering to self-centre, the steering will normally be designed with
positive caster. Normally caster angle of a vehicle is between 1~4 degrees.

1. 3. 5 Toe-out on turn
Toe-out on turns is defined as the difference of the steering angle between the two
front wheels when turning left or right by 20°. see Figure 1.5.When the vehicle turns,
the inner wheel angle is always bigger than the outer wheel, difference is about 2
degrees, the purpose is to make the vehicle turn by referenced to the instant center
point of the extend line of back axis.
Figure 1. 5 Figure 1. 6
1. 3. 6 Thrust Angle
Definition: The angle between the vehicle’s centerline and the vehicle thrust line. When
driving, the front wheels and the rear wheels should pull to the same side if the thrust
angle is not zero. When thrust line is at the left side of the vehicle’s centerline, the
thrust angle is positive, otherwise is negative. The existence of the thrust angle causes
the vehicle’s rear body pull to one side. In order to drive the vehicle straight-ahead, the
front wheels have to turn to the direction of thrust line. If thrust angle compensation is
not done for front toe, the steering wheel must be turned to one side when driving
straight-ahead. If rear toe can be adjusted, the thrust angle should be adjusted close
to zero. The direction of thrust line is the actual driving direction of the vehicle, which
is determined by rear toe. When the direction of thrust line doesn’t coincide with the
geometric centerline of the vehicle, the steering wheel must be turned by some
degrees to keep the vehicle driving straight-ahead, so that unbalance phenomenon of
the steering wheel is caused. At the same time, the traveling paths of rear wheels don’t
coincide with that of front wheels. This kind of phenomenon is called Rear Wheel
Lateral Move. If ignore the thrust line, the veracity of alignment cannot be ensured.
This is the main reason of the steering deflection. If you select the thrust line as the
measurement datum, you can perform the following operation procedures:
After adjusting rear toe to the specified value (OEM Specifications), the thrust line will
coincide with the vehicle’s centerline. For the vehicle with adjustable rear suspension,
rear toe should be adjusted to keep the thrust angle close to zero. No matter the
thrust angle is zero or not, the steering wheel can be adjusted balanced if you take the
thrust line as alignment datum. If rear toe cannot be adjusted, please adjust front toe,
and keep it be same with rear toe, and then set them to the angle by which the steering
wheel can be balanced.

1. 3. 7 Wheelbase diff.
Wheelbase difference is defined as the angle between the joint line of the centre of two
rear wheels and that of the front wheels. It is positive when distance between the
centre of the right wheels is large than that of left wheels; and negative otherwise. If
the tread is available from the vehicle specifications, then the wheelbase difference can
be also expressed by angle. See Figure. 1.7.
+

Figure 1. 7 Figure 1. 8
1. 3. 8 Track Width Diff.
Track width (Tread) difference is defined as the angle between the joint line of the
ground-contact point of left wheels and that of the right wheels. It is positive when
distance between the centre of the rear wheels is large than that of front wheels; and
negative otherwise. If the wheelbases are available from the vehicle specifications,
then the tread difference can be also expressed by angle. See Figure 1.8.
1. 3. 9 Left (right) lateral offset (angle)
The offset of rear left (right) wheel and front left (right) wheel at the vehicle’s lateral
direction. When rear left (right) wheel is outside of front left (right) wheel, left (right)
lateral is positive, otherwise, it’s negative. The angle between the trust angle and the
left (right) front/back wheel center line is the left (right) lateral offset angle.
1. 3. 10 Axle Offset (angle)
The relative offset of front axle and rear axle at the vehicle’s lateral direction is defined
as Axle offset. When rear axle is more to the right side than front axle, axle offset is
positive, otherwise, it’s negative. The angle between the center line of the difference
angle and the trust angle is defined as axle offset angle.

GA-600S 3D Wheel Aligner User Manual
1-6
1. 3. 11 delay (angle)
The same axle’s relative offset in longitudinal direction of the vehicle is called the delay.
When the right wheel is behind of the left wheel on the same axle, the delay is positive,
otherwise, it’s negative. The angle between the wheel center line and the vehicle
longitudinal geometric center line vertical is called the delay angle.
1. 3. 12 Included angle
The sum of Kingpin inclination angle and camber angle is called the included angle.

Chapter 3 Basic Operation Procedure
3. 1 Precheck
Ask the owner for vehicle drivability problems, symptoms, and wheel alignment history,
and find out vehicle information such as make, model and year, etc. Check each chassis
part carefully, include dust cover, bearing, rock arm, tripod-ball, shock absorber, tie rod
ball and steering mechanism, for any loose or wear. Then check to see if the tire
pressure, tire treads of the left and right wheels are alike. Perform the wheel alignment
checking after the initial condition is known. If the measuring values do not accord with
the specifications given in the databank, the wheel alignment should be adjusted. After
finishing the wheel alignment, test the vehicle to see if the abnormal conditions are
eliminated. Re-adjust the wheel alignment if necessary.
3. 1 Alignment Measurement
After precheck, can start alignment measurement.
3. 3 Adjustment
In the alignment measurement, based on the measurement results, combined with the
actual vehicle alignment fault phenomena, with reference of the OEM specs, to make
corresponding adjustments according to the actual situation.
3. 4 Test Run
The vehicle shall be test derived, after alignment adjustment, to confirm if the fault
phenomena are eliminated. Otherwise, shall redo the adjustment.
