1．Adjustment of .4-Wheel Alignment
Test and adjust the front wheel alignment value and adjust the toe on the 4-Wheel Alignment meter.
a. Adjustment of kingpin castor: The standard value is 3°30′±30′(adjust the difference of left and right kingpin
castor to within 30′);
b. Adjustment of toe: The toe with standard value of 0～2mm is adjusted by rotating the steering cross rod. When adjust
the toe, it should rotate the cross brace in left and right side evenly. Tighten the lock nut after adjustment, the torque is
55 - 65N·m.
c. Centering and fix of steering wheel: according to the display of the alignment gauge, turn the front wheel to right
ahead, after removing the steering wheel without changing the position of steering lever, mount the steering wheel
with center aligned, the radials of the steering wheel shall be in the bilateral symmetry position, and the symbol of
Great wall on the steering wheel shall be in the confrontation position of the driver, tighten the nut, with a tightening
torque of 25 - 35N·m.
Left wheel left steering: 32, right wheel left steering:28;
Left wheel right steering:
28, right wheel right steering: 32;
b. Under the light condition of the car, the height between the center of front axis fixed bolt of the lower suspension arm to the
ground is 295
1mm, if the dimension is not within this scope, reach it through adjusting the torsion bar adjustment arm
bolt;
c. The reference dimension of the height of the car is : the left and right deviation is less than 10mm;
3. Checking the free gap of steering wheel:
Turn the orientation of the car to front, stop the engine, exert a force of about 4.9N on the steering wheel along the circumferential
direction to make the it turning to the left, there is resistance force, stop turning when the resistance force is growing; then turn
the steering wheel to the right, stop turning when the resistance force is felt to be growing; the radian value that the external edge
of steering wheel runs is the free gap of the steering wheel, its standard value shall be less than or equal to 20
, and the corner
from the central position to the left or right shall be no larger than 10.

Front wheel alignment
1. Process the following inspection and eliminate
all problems
a. Check the wear condition of tyre and proper inflation.
Tyre inflation pressure: 230kPa
b. Check the wheel bearing of front wheel for loose.
c. Check the front suspension for loose.
d. Check the steering drive device for loose.
e. Process the standard elastic test; check thefrontvibration damper
for normal operation.
3. Install the 4-Wheel alignment instrument
Processed according to the detailed description of equipment
manufacturer.
4. Adjust the wheel angle
Remove the cover of spacing bolt of steering knuckle; check the internal
wheel’s steering angle A.
Internal wheel’s steering angle:
32
Caution: The wheel should not touch the brake hose of car body
when the steering wheel is rotated to limit.
2. Adjust the height of car
A:Adjust the height of car to the standard value for theconvenience of
processing the front wheel alignmentinspection.
B: Front fixed bolt of lower suspension arm
The standard no-load height is: the center of front fixed boltof lower
suspension arm is 295
1mm away form theground.

6. Adjust the wheel toe
Adjust the wheel toe according to the following method
a. Shake the car upwardly and downwardly to make the suspension
reach the stable status.
b. Push the car forwardly for 5m in flat ground when the front
wheel is in the straight forward position.
c. Mark the center of each rear wheel; measure the distance “B”
between the marks of left and right tyre.
d. Push the car forwardly to move the mark on the back of tyre to
the position of front instrument.
Remarks: if the tyre moves too far, repeat the procedure (b).
e. Measure the distance “A” ‘between the marks on front of tyre.
f. Measure the toe of wheel.
toe =B-A
Inspection standard: 0-2mm
If the toe does not consist with the specified value, it can be
adjusted by the left and right draw-bar.
Move the vehicle forwardly
g. Adjustment of toe: the standard value is 02mm. The toe is
adjusted by rotating the cross draw-bar. When adjust the toe, it
should rotate the cross draw-bar on left and right side uniformly.
After the adjustment, tighten the lock nut, the tightening torque
is 55
65Nm.
