Introduction
Thank youfor using KWA-3003D wheel aligner
manufactured by LAUNCH TECH CO., LTD.
Definition
KWA-300 3D Wheel Aligner is aprecision
measurement instrument designed to measurethe
wheel alignment parameters and compare them
with the specifications provided by vehicle
manufacturer.It also gives instructions to the user
for performing corresponding adjustments so as to
get the beststeeringperformanceandreducetire
wear.
WhenIsWheelAlignment
Required
lThe driver mustfirmlyhold thesteering wheel
to maintain a straight-ahead driving.
lAbnormal wear of tires occurred, such as single
side wear,concave-convexity wear and
featheriness wear.
lToo heavy ortoolight steering, orshakingat
high-speed driving.
lWhen the tire(s), steering joint or shock
absorber are replaced.
lWhen the vehicle is impacted.
lWhen the vehicle has driven for the first
3000km or 10000km.
MainVehicleAlignment
Parameter
The wheel alignment mainlyconsistsof camber,
caster,toe-in, kingpin inclination, toe-out on turns,
wheelbase difference, tread difference, etc. They
are designed mainly toimprovethe steering
performance and driving stability of the vehicle,and
reduce tire wear.
Toe-inand Toe-out
The toe settingisthe amountbywhich thefrontor
rear wheels point inwardsor outwards atthe frontof
the wheel in relation to each other (see Fig.1.1).
When the wheels point inwards they are saidto
toe-in. Toe-in figures aregiven apositive value.
Conversely when the wheels point outwards they
are said to be toe-out and the figures are shown as
a negative value.
Fig.1.1
The purpose of correct toe isto ensure that the
wheels run parallel when thevehicle is driving.An
incorrect toe setting may affect the stabilityand
controllability of the vehicle.
Camber
Camber is the leaning of the wheel inwardsor
outwards from the vertical.
If the road wheel leans outwards from the vertical, it
is said to have positive camber and when leaning
inwards from the vertical -negative camber,looking
from the front or rear of the vehicle. See Fig.1.2.
Fig.1.2
Camber is measured in degrees.
KingpinInclination
Kingpin Inclination (KPI) is the angle ofinclinationof
the king pin towards thecentre-line of the vehicle
from the vertical (see Fig.1.3).

LAUNCH KWA-3003DWheelAlignerIntroduction
1-2
Fig.1.3
Correct KingpinInclination can equalizethe loads
applied on bearings so that the life of bearings can
be prolonged and thecontrollabilityof steeringis
improved.
Without the inclination, thecontrollability ofthe
steering may beaffected; further more,the vehicle
weight and the ground counterforce may cause
significant stress inthe axleand finallydamagethe
axle.
Correct inclinationof king pinis also helpfulforthe
vehicle to restore itsstraight-aheadposition after
steering.
Kingpin Inclination is determined when the vehicle
suspension is designed. It is not service adjustable.
Caster
Caster is thetilting ofthe kingpin eitherforwardsor
backwards from vertical, as viewed from side of the
vehicle. See Fig.1.4
Fig.1.4
When the king pin is tilted backwards from the
vertical, caster is positive. When the king pin istilted
forwards, caster is negative.
Caster angle influences thedirectional stabilityof
the steering. Toincreasethe tendency ofthe
steering to self-centre, the steering will normally be
designed with positive caster.
Toe-outon Turns
Toe-out on turns isdefined asthe difference ofthe
steering angle between the two front wheels when
turning left or right by 20°as shown in Figure 1.5.
The inner wheel will turn more degrees than the
outer wheel when the vehicle is steered, the
difference is usually about 2°.This angle is
designed to reduce steering resistance.
Fig.1.5
Note: This angle can be tested when aturntable
is equipped for KWA-300 3D.
Thrustangle
The trust angle is defined according to the driven
mode of vehicle.
lRear wheel driven: the thrust angle equals half
of the toe-in difference between the tworear
wheels.As shown in Fig.1.6.
lFront wheeldriven: the thrustangleequals half
of the toe-in difference between the two front
wheels.
lFour-wheel driven: the thrust angle equals half
of the toe-in difference between the two front
wheels plus half of the toe-in difference
between the two rear wheels.
The trust angle isdefinedas positivewhenthe trust
line is towards left, and negative when the line is
towards right.
If the thrust angle is not zero, the vehicle will have
the side-moving trend. In this case, adjust the front

LAUNCH KWA-3003DWheelAlignerIntroduction
1-3
toe-in of the drive wheels first, and then adjust the
toe-in of driven wheels.
Fig.1.6
Wheelbase Difference
Wheelbase difference is defined as the angle
between the jointline ofthe centreof two rear
wheels and thatof 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 byangle. See Fig.
1.7
+
Fig. 1.7
TreadDifference
Tread difference is defined as the angle between
the joint line of the ground-contact point of left
wheels and that of the rightwheels. 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, thenthe tread
difference can be also expressed byangle. See Fig.
1.8.
+
Fig. 1.8
Left(right)lateral offsetangle
The relative offset in lateral direction between front
axle and rear axle of vehicle is axle offset. When
rear wheel axle isoffset to right fromthe front wheel,
the axle offsetis positive, otherwise isnegative. The
angle between the bisector of the tread difference
angle and the thrust line is axle offset angle.
Axleoffsetangle
The relative offset in lateral direction between front
and rear axle of vehicle is axleoffset. When LR (RR)
wheel is offsetoutside fromLF (RF) wheel, theleft
(right) lateral offset is positive, otherwise is negative.
The angle betweenthe connectingline fromthe
front wheel center point to the rear wheel center
point (same side) and the thrust line is left (right)
lateral offset.
Delay angle
The angle between the connecting line from the LF
(LR) wheel center pointto theRF(RR) wheel center
point and the perpendicular ofthe longitudinal
geometry center line is called front (rear) delay
angle. Whenthe rightwheelon thefront (rear) axle
is behind the left wheel, the front (rear) delay (angle)
is positive, otherwise is negative.
Includedangle
The sum of the KPI (Kingpin inclination) and the
wheel camber is called included angle.
