Chery A series. Manual - part 65

------Measure the height from the wheel center to the mudguard edge. The measured 
difference from left and right should be not more than 10mm. 

 

 

 
 
 
 
 
 
 
ALIGNMENT OF THE REAR WHEEL 

 

It is recommended to utilize the four-wheel alignment tester with thrust line positioning 
method on this type of chassis. 

Note: thrust line positioning is defined as adjusting the front wheel toe-in based on the 
rear wheel thrust line.   

With the thrust line positioning, the adjustment of the rear wheel toe-in will influence the 
single front wheel toe-in, so during four-wheel alignment, the rear wheel should be adjusted 
before the front wheel alignment.

 

 

Measure the vehicle height 
------Rear measure point 

From ground to the center of the joint bolt of 
the rear axle and the body (as the arrow 
shows) 

Precaution: Check whether the height from 
left and right are same before processing 
the wheel alignment 

------If there is a difference of the heights from 

left and right, that means there are 
damaged or deformed components of the 
front and rear suspension.

 

 

Install the wheel alignment tester on wheel 

 

------Please refer to the specific instruction of 

manufacturer for the wheel alignment 
tester.

Rear wheel caster 

-1°30′±10′ 

 

Note: The rear wheel caster cannot be adjusted. If there is abnormal wear on the tire of 
the rear wheel, so check whether there are worn or deformed parts on the rear 
suspension 

Check the rear wheel toe-in

Rear wheel toe-in 

20′±10′ 

 

Note: The rear wheel toe-in out of standard range may lead to wear on shoulder of 
tire on both sides. If the differences of the rear wheel toe-in both rear wheel are too 
much, the vehicle running direction may be affected. Therefore the rear wheel toe-in 
is a vital parameter of the alignment angles. 

 

 

ALIGNMENT OF THE FRONT WHEEL 
------Install the wheel alignment tester on the wheel 

Please refer to the specific instruction of manufacturer. 

------Check and adjust the wheel camber and the kingpin caster of the front wheel 

according to the standard 

 

Angle Value 

Front wheel camber 

-30′±20′ 

Kingpin caster 

1°30′±30′ 

Note: Adjust the caster before the camber 

 

Kingpin caster 

There is no need to adjust the kingpin caster for it is assured by the structure of design

Influence of caster 

The main function of the caster is to keep the vehicle running straight forward. If the caster is 
positive, the inside of the vehicle descends and the chassis ascends which increase the 
steering knuckle load when the front wheel turns. If the casters of two wheels are same, the 
vehicle will return forward after turning. Increasing the positive caster angle will enhance 
stability of the steering wheel while the steering force will be increased at the same time. 
Decreasing the positive caster may reduce stability of the steering wheel but lightens the 
steering force. 

The angle of the caster could not make the wear on tire. It is used to stabilize the steering 
direction and to return automatically after steering. If the vehicle is equipped with a 
traditional manual steering wheel, the caster is small or even tends to negative, which makes 
the steering easy. If the vehicle is equipped with a power steering wheel, the caster is usually 
set to be large positive in order to offer the driver a better feeling. Increasing the positive 
caster will increase the steering force but enhances the stability of straight running. 

 
 

Adjust the camber 

 

 

Under normal condition, there is no need to 
adjust the camber after assembling the 
independent suspension and the wheel 
steering knuckle. Use the joint bolt of the 
independent suspension and the steering 
knuckle to calibrate the wheel camber if the 
camber is out of the tolerance range for other 
reasons. 

----Check (visual inspection) whether there 

are damaged parts in the steering system 
and replace the damaged ones before the 
calibration. 

----If the front wheel camber is out of the 

tolerance, loosen the joint bolt of the 
front shock absorber and the steering 
knuckle and move the wheel to calibrate.

 

 

----

For the further calibration, use the 
substitute bolt to adjust the wheel 
camber. Replace the M12 bolt with the 
M11 bolt. The camber is allowed to be 
adjusted within about ±1° shown as the 
illustration

----

The connection between the lower 
control arm of the suspension and the 
steering knuckle is clearance fit. 
Loosen the joint bolt, move the wheel 
and adjust the camber. 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

 

 

 

Check the front wheel toe-in 

Toe-in (general) 

Car No. 

Chery A15LHD 

Front wheel toe-in 

0′±10′ 

Tightening torque of toe-in: 55±5N•m. 

Adjust the toe-in 

Optical tester or mechanical toe-in adjuster can be used to adjust the toe-in. 

----

According to the tester’s requirement, make the wheel alignment well before the 
adjustment; 

----

Loosen the lock nut and the elastic cover snap ring of the right steering tie rod, and 
then screw the toe-in adjusting rod till the length of the rod reaches the specified 
value. 

----

Tighten the lock nut and reinstall the elastic cover snap ring. Check whether the lock 
nut is tightened enough and cover is in the correct position. 

----

After adjusting the front wheel toe-in, check whether the steering wheel is level. If not, 
loosen the lock nut of steering wheel, and then adjust to the level position. The 
tightening torque of the steering wheel lock nut is 55±5N•m as required.
