door whether there is squeak sound.

–

Use smear grease to lubricated the door hinge.

the engine is cold)

Check the manual shift assembly.

–

Switch between gears and verify the squeak.

–

Remove the floor console shift lever, lubricate it and install
it.

Wind Noise/Air Sound

External Wind Noise

The wind noise leak repair is very similar to that of water
leaking. Refer to

1.11.1.1

Diagnostic Information and

Procedures

. The actual repair procedures depend on the type

of seals.

Vibration

Tire and Wheel Balancing (On-Vehicle)

Carry out the balancing on the electronic wheel balancing
machine. Dynamic balancing machine is easy to use and can
be used both for static balance and dynamic balance. Unlike
the balancing on vehicle, the off vehicle balancing can not
correct the brake disc imbalance. However, the accuracy of the
off vehicle balancing can overcome this issue. Make a cone
through the center hole on the back, rather than through the
wheel nut holes.

Tire and Wheel Balancing (Off-Vehicle)

On-Vehicle tire and wheel balancing can correct the imbalance
caused by disc brake vibration.

Warning!

Support the control arm at the normal position to avoid
damage to drive axle. When the wheels travel to the
maximum low position, do not shift the gear lever.

1. Do not remove the balance weights during on vehicle tire

and wheel balancing.

2. If the balance weight is more than 25g (1lb), divide it into

two blocks and install one onto the inner wheel rim and the
other onto the outer wheel rim.

3. Engine driven gear and gear assembly.

Tires and Wheels Installation

Tires and wheels are installed at the factory. with the radial tires
thicker parts (also known as the high point) pointing to the
minimum radius wheels (also known as low points).

Red paint marks or labels are at high points along the outer of
the tires.

Before remove the tire, mark the position of the valve to make
sure it can be installed back to the original position.

Abnormal Sound

Abnormal Sound Repair

Abnormal sound mainly comes from parts that should not have
relative motion. To repair abnormal sound, there are three
ways:

–

Tighten the fasteners, so that there is no relative motion.

–

Separate parts, so that components do not contact.

–

Isolated parts, so that there is no abnormal noise when
parts moving. Even low friction surfaces can be used to
eliminate viscosity between the sliding parts.

Information

and

Procedures

Water Leaks Diagnosis

Note

Identify all water leaking parts before repair. Random
repair may only be a temporary solution and could lead
to more difficult repair in the future. Continue testing to
identify all water leaking parts.

To repair water leaks, proper testing and diagnosis is needed.
Adjust the position of the incorrectly positioned parts and use
proper materials to carry out the repair. Firstly, determine in
what circumstances there is water leaks. For example: only
when the vehicle remain in the slope there is water leaks.
Secondly, if the water leaks area has been found, use water
hose to locate exact position where water leaks. If water leaks
is not obvious, use a water leaks testing machine to identify
specific locations. Removal certain parts may be required to
identify the specific location of water leaks.

Water Leaks Test Preparation

–

The vehicle is designed for running under normal
conditions.

–

The sealing materials and components design has taken
into account the natural environment to achieve the seal
strength. However, there are other factors affecting seals.

–

Water leaks test is related to the natural environment and
can be used to determine the vehicle driving performance
under normal conditions.

–

The first step of the diagnosis process is to determine water
leaks occurred under what conditions. If you can determine
the approximate water leaks area, you can use a water
hose water to isolate the exact location. To repair water
leaks, you may need to remove certain parts of the
decorative panels or components.

–

If the water leaks appears in the door, trunk door or window,
it is not necessary that the water leaks is created by sealing
strip. Adjust these parts might correct the water leaks.

Testing With A Water Hose

Note

Do not use water hose with a nozzle.

1. Let an assistant inside the vehicle to confirm the exact

location of water leaks.

2. Start testing from the bottom of the window or the

windshield.

3. Move the hose slowly upward, until cover the entire roof.

Ventilation Hose Test

Note

Ventilation hose test can only be used for completely
cured the adhesive. Otherwise, the usage of this method
will damage the adhesive layer, leaving increased water
leaks spots.

1. Pour liquid cleaning agent into a spray bottle according to

a certain percentage, then spray it to window edge. Spray
from the bottom, gradually upward and through the entire
roof.

Note

The pressure of compressed air can not exceed 205
kPa (29.75 psi).

2. Let an assistant bring the air hose into the vehicle.

3. Let the assistant use the compressed air targeting

suspected leaking area. If there is leakage, air bubbles will
appear.

1.11.1.2 Repair

Body Leaking Repair

Depending on the location of water leaks, certain parts may
need to be removed.

1. From the inside or outside the vehicle, slit open the seam

adhesive.

2. Clean and remove all the old adhesive residue from the

leaking area.

3. Apply body and joint sealant on the cleaned area.

4. Wait for several hours so that the sealant is fully cured.

5. Inspect whether there are water leaks.

6. Reinstall parts.

Fixed Window Water Leaks Repair

Depending on the location of water leaks, certain parts may
need to be removed.

1. Determine the specific location of water leaks.

2. If the windshield edge leaks, use a dedicated seam

adhesive to repair or replace the windshield.
