Comprehensive Repair Instructions
1. Use the splasher, backing, and carpet to keep the vehicle
clean and to prevent damage.
2. W h i l e r e m o v i n g , m a r k a l l v e h i c l e c o m p o n e n t s o r
place all the components in proper order to make re-
assembling more convenient.
3. Disposable parts:
(a) Always use new parts to replace cotter pins, gaskets, O-
rings, and oil seals.
(b) Disposable parts will be marked with a "" in the
components schematics section.
4. Precoated components.
The precoated components include bolts and nuts which
have been coated with locking sealant in the factory.
(a) If the precoated part is tightened, loosened, or moved
for certain reason, it must be coated with prescriptive
sealant again.
(b) When reused, the original sealant should first be
cleaned and dried using compressed air. Afterwards,
use the required locking sealant to coat the bolts, nuts,
or threads.
(c) Precoated parts are marked with "" in the components
schematics section.
5. All rules regarding a bolt's tightening torque must be
seriously obeyed, and a torque wrench must be used.
6. Be careful when using a jack to raise and support the
vehicle. Make sure to jack up and support the vehicle
at proper locations.
(a) To ensure safety, chock up the wheels of the opposite
side if the place to be jacked up is either the front or
back of the vehicle.
(b) After lifting the vehicle, make absolutely sure to
support it with a bracket. It's extremely dangerous to
perform maintenance using merely a jack, even if to
finish the small matter quickly.

General Repair Methods and Operations
1. If a jack is needed, please kindly comply to the safety procedures liste\
d below.
2. Park the vehicle on a flat surface, stablize the front and the back wheels using any fixed object or tool,
jack up the vehicle, support it with the chassis, and then start the mai\
ntenance.
3. Disconnect the battery's negative cable before maintenance, in order to reduce the possibility of
damaging and burning out the cable due to a short circuit.
4. Cover the vehicle body, seats, and floor to prevent them from being damaged and polluted.
5. Handle brake fluid and antifreeze fluid carefully, because it may damage the vehicle's surface paint
and its surroundings.
6. Using the proper tools or basic tools that have been recommended and are purchasable is very
important in guaranteeing an effective and reliable maintenance result.
7. Dispose the used dowel pins, gaskets, O-rings, oil seals, lock washers, and self-locking nuts. Prepare
new parts for installation. Normal functions are not guaranteed if these\
parts are reused.
8. Store the removed parts in order and in groups to make reassembly more c\
onvenient.
9. Store bolts and nuts separately, because their hardness levels and designs are different according to
the installation locations.
10. Clean parts before they are inspected or reassembled. In addition, parts that come in contact with
engine oil also need to be cleaned, as well as checked for blockage by u\
sing compressed air.
11. Before installation, use engine oil or grease to lubricate the rotating and sliding sides of the necessary
parts.
12. When necessary, use sealant on gaskets to avoid leakage.
13. Please carefully comply to all tightening torque specifications of b\
olts and nuts.
14. After maintenance, check to make sure whether the repairs were performed correctly and whether the
malfunctions have been fixed.
Vehicle Lifting/Lowering Procedures
When lifting the vehicle, the lifter must be placed at the indicated spots. Using these indicated spots
incorrrectly can lead to permanent deformation of the vehicle body. Many vehicle service stations
have autolifts that raise vehicles by supporting certain vehicle parts. If using other types of lifts, be
careful to prevent damages to the fuel tank, oil filler, or the base of the vehicle body.

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.
1. Wheel shimmy important points[C]: Counterweight not yet added
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.

2. Loosen the riveted areas of the front drive shaft nut
and remove the nut.
3. Inspect the front brake disc plate surface runout.
When measuring, tighten the two wheel nuts' symmetrical
locations. The front brake disc's brake linings runout on the
two sides should be no more than 0.11 mm. If oversized,
they should be repaired or replaced.
4. Inspect front brake disc thickness.
Standard thickness: 22.0 mm
Minimum thickness: 20.0 mm
The brake disc must be changed when it reaches the minimum
level of thickness.

(d) Measure the front hub bearing's starting torque.
Put the SST on the wheel bolts which are at the symmetric
locations. Put a dial torque wrench on the SST to slowly
rotate the flange assembly (45°/4s), requiring a starting
torque range of 0.1-0.3 N·m.
If the bearing rotation is not flexible, the front hub flange
plate surface movement inaccurate, or front hub bearing
starting torque is too much. The assembly must be replaced.
Steering knuckle's front hub bearing and
front hub flange assembly
1. Removal and inspection of front hub flange assembly.
(a) Use SST like a hand held travel hammer to repeatedly
hammer off the front hub flange assembly from the
steering knuckle and front hub bearing. Remove the
front hub with bearing's inner ring.
(b) Remove the bearing's inner ring on the front hub.
Use SST to remove the bearing's inner ring.
