2、Camber angle
Under normal circumstances, the camber angle does not have to be adjusted after the car
is equipped with the independent suspension system and wheel knuckles. In the case that
the wheel camber angle is detected to have bias from the allowances due to some reasons,
alignment can be made by way of adjusting the connecting screw nuts for the independ-


ent suspension system and the knuckles.

(1) (2)

(1) First check (visually) to see if there are any
damages on the driving system parts and components
before doing the alignment. Replace the damaged parts
or components if there are any. The camber angle
designed and set for the front wheels by the manufacturer

Adjustment of

screw nut

cannot be adjusted;

(2) In the case that the front wheel camber angle is detected to exceed the allowed bias,
loosen the connecting screw nuts for the front absorber and the knuckles, and move the
wheel for proper alignments.

3、Toe-in
Special four-wheel positioning testers should be used to test and adjust the toe-in.

(1) Make preparations prior to the adjustments as required by the tester. Use the steering
wheel limiter available on the marketplace to fix the steering wheel in the straightforward
direction (the steering wheel must be in the center position±5 degrees, and the lower
clamping flange of the steering axle should keep horizontally leveled).
(2) Loosen the locking screw nuts (1) of the
steering horizontal drawbar.

(3) Remove the elastic protective clip ring (2)
with a pair of pliers.





Attention: Replace the clipping ring if it is not elastic enough.
(4) Turn the toe-in adjustment rod to adjust the length as
needed till it meets the specified value.
(5) Tighten the screw nut (1) and re-install the protective elastic clip ring (2), check to
see if the locking screw nut is tight enough and if the position of the protective sheath is
correct or not.
(6) Upon completion of the adjustments for the front wheel toe-in, check to see if the
steering wheel is leveled. If not, loosen the locking screw nut of the steering wheel and
adjust the steering wheel to the leveled position. Tighten the locking screw nut till it
meets the torque specification (30±3Nm).

4、Check and test the front wheel steering angle
After the horizontal drawbar joint is replaced or the toe-in is adjusted, the steering angle
should be checked. If it fails to meet the specifications, the length of the left and right
horizontal drawbars should be checked and adjusted.

IV. The toe-in and camber angle of the rear wheels cannot be adjusted.

Check the camber angle and toe-in of the rear wheels. If they fail to be in the specified
limits, check to see if there are any deformed parts. Replace the defective parts.
