2Camber 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. 
 
3Toe-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).

4Check 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.
