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.

Areas of Importance
1. Clutch Rigid Pipe Installation
Before installing, check to make sure that the rigid pipe flare contact area is in good condition, the pipeline is
clean, and that there is no foreign materials.
2. Clutch Hose Installation
Check the surface of the clutch hose to make sure that there is no scuffing and that the pipeline is clean.
3. Coat grease on the U-joint of the pedal and the master cylinder.
4. Strictly adhere to the set torque guidelines when tightening the pipe fittings.
Rigid pipe and the master cylinder: M10 16±2 N·m
Clutch rigid pipe and hose: M10 16±2 N·m
5. While the clutch system is undergoing the exhausting process, make sure that all the air bubbles in
the pipeline are cleared out. Then check the brake fluid level in the reservoir, it should be between
MIN and MAX.

The numbers in the table represent the order of the possible malfunction causes, so be sure to check each part in
turn. If necessary, replace the part.

037A Transmission’s Overall External Schematics
The 037A transmission is a step mechanical transmission with differential, two-shaft front wheel drive
application. The forward gear has adopted the inertia synchronizer gear-shifting mechanism, which offers
smooth and easy gear shifting, reduces noise dramatically, and improves the service life of the gear - important
in achieving the overall economical efficiency. Regarding its control mechanism, the set steel ball and spring
allow the shifting gear to be quick, accurate with solid handling. The 5th gear transmission is equipped with an
interlocking mechanism to prevent accidental switching to reverse, to im\
prove driving comfort and reliability.

Steering knuckle assembly removal
1. Preparation
First, remove the front wheel, the front shock absorber with
coil spring assembly, and the steering knuckle coupling
bolt in turn. For detailed steps, please refer to the removal
of the wheel and the front shock absorber with coil spring
assembly.
2. Remove propeller shaft nuts
(a) First, pry the flattened areas of the propeller shaft's nuts
into a circle with a chisel.
(b) Half-insert a long bolt or metal bar into the brake disc
holes to loosen the nuts (shown on the left).
Tightening torque: 225±20 N·m
Front Suspension
Components
(c) Pull out the mount point on the steering knuckle to
separate it from the mounting bracket under the front
shock absorber. Prop a wood stick or metal bar against
the propeller shaft's outer end, and then hammer the
stick or metal bar to get the propeller shaft out of the
hub (shown on the left).
Caution: When hammering, prop it up against the shaft
end's location holes (middle recess). Be sure not to
damage the thread.

bly removal and installation
1. Hoist up the vehicle so that the front suspension is in a
free suspension state.
2. Remove the wheel speed sensor and the brake hose.
Remove the wheels and take out the brake hose from the
shock absorber bracket. Then remove the wheel speed sensor
wire harness (shown on the left) from the steering knuckle.
3. Remove the coupling bolt between the front shock
absorber and steering knuckle and the brake hub
assembly.

4. Loosen the mounting nuts of the front shock absorber
and remove the front shock absorber with coil spring
assembly (shown on the left).
Tightening torque: 40±5 N·m
5. Installation of the front shock absorber with coil spring
assembly.
Installation follows the reverse order of removal, but
please pay attention to the areas of importance below:

Remark: When removing the subframe's front mounting bolt,
an extension bar should be inserted through the lower swing
arm's hole. Positions shown on the left.
5. Subframe installation.
Installation follows the reverse removal steps.
Caution: Fix the position of the subframe with the
position pin, to avoid influencing the four wheels'
positioning. Location hole is shown on the left: a total
of two, one on the left and one on the right.
Stabilizer bar removal and installation
1. Remove the hanger rod.
Use a M10 open-end wrench to lock the sliding side of the
hanger rod (slightly higher than center position), screw off
the hanger rod lock nuts, and remove the hanger rod.
Caution: These are non-metal insert lock nuts, and
cannot be reused. So please replace them with new
ones after removal.
2. Remove the stabilizer bar arm.
Remove the stabilizer bar bracket mounting bolts Q1400830
(d2=13.5), and take down the bracket and bushing. As shown
on the left: There are four bolts, two on the left and two on
the right.
Tightening torque: 23±3 N·m
3. Stabilizer bar installation.
Install it by reversing the removal steps, but please pay
attention to the areas of importance below:
(a) During removal, please remember the installation order
of each of the hanger rod's components, so as to avoid
