Correct vehicle maintenance and repair is very important
to the safety of the maintenance person and the vehicle. If
any vehicle part change is necessary, please use a part with
the same part number or part number specified by the Great
Wall Motor Co., Ltd. Never use a part that has not been au-
thorized by the Great Wall Motor Co., Ltd.
4. Inspect the front brake disc thickness.
Standard thickness: 22.0 mm
Minimum thickness: 20.0 mm
The brake disc must be changed when its thickness falls be-
low the minimum level.
The maintenance procedures are explained step by step:
• The schematics and diagrams illustrate how and where to
operate.
• The titles convey the maintenance content.
• Detailed instruction explains how to perform the maintenance,
as well as introduces other related matters, such as specifications,
warnings, and so on.
For example:

Vehicle Body's Basic Calibration Measurements
This section shows the basic parameters of the overall vehicle. Please refer to this section when servicing or
repairing.
• All figures used to express measurements are actual figures.
• Measuring points are taken from the center of the mounting holes.
• When using the gauge, adjust the two measuring needles until they reach an equal length, then check
the measuring needle and the gauge itself to ensure there are no gaps.
• When using measuring tape, make sure not to stretch, twist, or bend it. \
• The asterisk (*) symbol after a numerical measurement value indicates that the other side's
symmetrical position is of equal value.
• Coordinates of the measuring points refer to the distances measured between the point and "X", "Y",
and "Z" standard lines.
• The left & right symmetry points of a measuring point's coordinate represent a coordinate point on the
left side, and that the right and left side are symmetrical.

Vehicle road test methods
1. Drive the vehicle and find out if the swaying is coming from the front tires or the back tires. Then replace the
identified problem tire with a good tire (one that has been tested on t\
he same model of vehicle).
2. If unable to determine the problem tire, replace the rear wheels. Continue with the road test. If the driving
condition obviously changes, replace the original tires, and only switch one at a time until the problem tire is
identified.
3. If no obvious improvement, replace all four tires with good tires, and then replace the original tires one by
one following the steps mentioned above.
Tire's abnormal wear and tear
Tire's abnormal wear and tear includes uneven and excessive
w e a r o f t h e t i r e . T h e r e a r e m a n y c a u s e s f o r t h i s . F o r
example, improper tire pressure, tire rotation has not been
timely maintained, bad driving habits, abnormal front wheel
location, etc.
Change the tires when the below situations happen:
1. When the extents of wear and tear of the front and rear
tires are different.
2. When any of the tire's tread has uneven wear and tear.
3. When the extents of the wear and tear of the left and right
front tires are different.
4. When the extents of wear and tear of the left and right rear
wheels are different.
5. When the groove of the tire tread wear appears abnormal
and the tire's contact area starts to flatten.
Inspect the front wheel alignment when the following
situations occur:
1. When the extents of the wear and tear of the left and right
front tires are different.
2. When any of the tire's tread has uneven wear and tear.
3. When the tread pattern strip or pattern block of a front
tire's single side is badly worn.
[A]
[B]
[A]: Steering problems, air pressure not sufficient, or tire rotation has not been timely maintained. [B]: Abnormal front wheel alignment, tire or wheel structure is not the same.
Radial tire sway
Here the sway means the vehicle's front or rear part shakes
from side to side, together or individually. Tire sway is
caused by the steel wire belt inside the tire not being straight.
The sway is the most obvious when the vehicle runs at the
speed of 8-48 km/h.
Road tests can help finding malfunctioning tires. If the
malfunction is with the rear tires, then left and right shaking
or "swaying" would take place at the back of the vehicle.
Here the driver of the vehicle would feel as if someone were
pushing from one side of the vehicle.
If the malfunction is with the front tires, swaying would be
even more obvious. The metal plate in the front may seem
moving back and forth, and the driver feels as if he/she were
at the vehicle's center of rotation.
Wear marks
There are several tread wear marks (refer to location A in the
diagram shown on the left) inside of the tire's pattern groove.
These marks indicate that the tire has been worn to the point
of replacing.
Before the tire's usage limit, indicated by the remaining
pattern's depth, reaches 1.6 mm (and its main pattern groove
bottom protrudes to the same level), for your safety, please
replace the tire.
When serious eccentric wear leads to the partial protrusion
of the cord fabric level, or outside objects damage the tire to
a depth that reaches the cord fabric level or steel band level,
stop using the tire.

Dynamic balance and static balance
There are two types of wheel balance: static and dynamic.
Picture 1 shows static balance. Picture 2 shows dynamic
balance.
Static balance means that the weight distribution around the
wheel is equal. If the wheel is static and unbalanced, violent
vibrations may be created, called jump vibration.This kind
of situation can ultimately lead to the uneven wear and tear
of the tires. Shown in diagram 1.
Dynamic balance means that the weight distribution on the
two sides of the medium plane of the wheel is equal, so
during the rotation process, the tire assembly cannot create a
tendency for the medium plane of the wheel to shift from one
side to the other. If the wheel is dynamic and unbalanced, it
can create a shimmying effect. Shown in diagram 2.

2. Locations to add counterweight[D]: Counterweight added
3. Axis
Wheel maintenance
Do not use welding, heating, or hammering to repair wheels. All damaged wheels must be replaced.
If the vehicle's wheel is twisted or deformed, sunken or depressed, having too much horizontal or radial hop,
leaking air from the welded parts, stretched out at the bolt holes , having flimsy nut bolt lock, or severely rusty,
the wheel must be replaced. When the wheel is hopping too much, it will lead to undesirable vibratio\
ns.
When replacing the tire, be sure that the load capacity, diameter, rim width, offset distance, and the installation
structure of it, are equal to the settings of original wheel. If the wheel dimensions are not appropriate, this will
influence the wheel and bearing's life, brake cooling effect, speedometer and odometer calibration, vehicle
ground clearance, as well as the clearance between the tire and the vehi\
cle body, and the tire and vehicle chassis.
Wheel (steel wheel) removal
1. Remove the wheelhouse and loosen the nuts, 1-2 turns is
enough.
2. Hoist the vehicle.
3. Screw off the nuts and remove the wheel.
Nut tightening torque: 110±10 N·m
Caution: Heating methods absolutely must not be used
to loosen tightened wheels, otherwise the heat will
reduce its use life and damage the hub bearing.
Wheel (steel wheel) installation
Installation according to the reversed instructions used for
removal, and pay attention to the following requirements:
Wheel nuts must be tightened in proper order and according to
the specified torque, as to avoid wheel or brake disc deformity.
When installing the wheel house, be sure to line up the wheel
housing notch locations with the inflation nozzle.
Tightening sequence: A – C – B – D
Caution: Before installing the wheel, first clean off the
corrosion on the wheel's mounting surface and drum
brake or brake disc's installation surface with a wire
brush, in order to make the wheel installing easier by
making the space between its metal firmly connect
to the mounting surface, otherwise it may lead to the
wheel nuts loosening to the extent that the vehicle's
wheel may come off while driving some day.
