b. Rear measuring point

Check the height between the ground and the

connecting bolt that joins the rear axle to the

shock absorber. The body height of the left and

right wheels shall be identical.

Note: Prior to checking wheel alignment, firstly adjust the vehicle to specified height.

If vehicle height does not conform to standard, inspect the front and rear suspension of the vehicle

to confirm whether there exists damage or deformation.

c. Inspect wheel bearing clearance, and replace front-wheel bearing if necessary.

d. Inspect the status of wheel rim and tire.

e. Inspect the loosening level of steering linkage and ball joint.

f. Park the vehicle (without luggage or passengers) on a level ground.

g. Shake the wheel and inspect the loosening status of front suspension．

h. Inspect shock absorber to ensure its normal operation.

a) Inspect and avoid oil leakage.

b) Inspect the mounting bushing to avoid wear.

c) Inspect the damping force of shock absorber, and replace if not conform to

specification.

Note: fuel tank shall be half-full. Cooling water in radiator and the engine oil shall be at specified

height. Tire jack and driver's tools shall be placed at designated location.

2. Wheel Rim and Tire

1) Visual inspection

Inspect the tire and wheel rim, if there exists

crack, damage, deformation or other defects,

replace wheel or tire. As is shown in the right

figure.

Tire Wear

2) Tire wear

a. Refer to the standard tire figure to

inspect the tire thread depth of other

parts.

Minimum depth: 1.6mm

Tire for snow condition: 50% of the thread

depth

b. If wear indication strip appears, the

tire must be replaced.

High speed turning

Tire swap is not performed

Measure and adjust tire pressure.

Reduce vehicle speed.

Perform tire swap

(b)

Excessive high pressure of tire (central wear)

Tire swap is not performed

Measure and adjust tire pressure

Perform tire swap

(c)

Incorrect toe-in

Adjust toe-in

(d)

Incorrect camber angle or caster angle

Suspension system malfunction

Tire unbalance

Brake drum or disc out of round

Other mechanical problems

Tire swap is not performed

Adjust, repair or replace axle and parts of

suspension system

Repair or replace

Perform tire dynamic balancing or replace the tire

Calibrate or replace

Correct or replace

Perform tire swap

4) Precautions of wheel rim and tire

a. Never use defective wheel rim or tire.

b. Aluminum alloy rim is easily to be scratched, therefore, use soft cloth but never use steel

brush when cleaning. And never contact the rim with boiling water when washing the

vehicle by steam.

c. If abrasive compound (such as turbid water and ground mud) adheres to aluminum alloy

rim, please rinse the rim with neutral detergent as soon as possible to avoid damage.

5) Tire replacement

a. Prior to installing tire valve, firstly inspect the wheel to see whether the valve port of the

wheel is smooth and burr-free. Then apply glycerol to the valve rubber surface or soak

the valve into glycerol solution. Finally use special tools to apply a pressure of 200-400N

to press the locating ring on the valve to pass through the wheel valve port, thus it shall

be deemed as being installed to proper position (Soap water is allowed to substitute

glycerol).

b. Prior to installing tire, apply glycerol or soap water at the periphery of tire bead.

Meanwhile, if there is slight mark on the wheel rim, please align the tire uniformity

testing mark to the rim slight mark. If there is no slight mark, align the tire dynamic

balance testing mark to the position of wire valve. If there is no slight mark on the

wheel rim, and the wire has static balancing test mark instead of a dynamic one, align the

wheel valve to static balance testing mark.

6) Tire pressure

Inspect all of the tire pressures (including

spare tire) via barometer, and adjust if

necessary.

Inflate

the

tire

strictly

in

accordance with specified pressure value, and

the tire pressure shall not exceed the rated

pressure by 10% during inflating process. The

rated inflation pressure of the spare tire shall

be 2.5bar when the spare tire assembly is

separately installed, and the spare tire shall be

stored separately from the other 4 wheels.

Prior to aligning the wheels, inspect and adjust

the tire pressure: the front wheel pressure shall

be 2.0bar; the rear wheel pressure shall be

2.0bar, as shown in the right figure.

Inspection of Tire Pressure

7) Air leakage

Confirm whether there exists tire valve leakage,

as shown in the right figure.

8) Tire unflatness inspection

a. Lift the vehicle, and cautiously

support it.

b. Fix a micrometer (Φ10) with a

cylindrical contact tip to the rim edge,

then measure the unflatness depth, as

shown in the figure.

c. Replace the wheel rim if necessary.
