Yes

Step 2

Check whether the wheel positioning is normal?

No

Readjust the wheel positioning.

Yes

Step 3

Check whether the tire wear is normal?

No

Replace the tire. Note: After replace the tires,
immediately carry out the wheel positioning.

Yes

Step 4

Check whether the wheel run out is normal?

No

Measure the wheel flange run outs. If
necessary, replace the wheel hub.

Yes

Step 5

Check whether the steering tie rod ball joint is working properly? (wear, loose, etc.)

No

Tighten the nuts. If necessary, replace the
steering tie rod ball joint.

Yes

Step 6

Check whether the lower control arm ball joint is working properly? (wear, loose, etc.)

No

Tighten the nuts. If necessary, replace the
lower control arm ball joint. Refer to

4.2.7.7

 

Lower Control Arm Ball Joint

Replacement

Yes

Step 7

Check whether the wheel run out is too great?

No

Measure the wheel run out, re-assemble the
wheels and tires. If necessary, replace the
damaged parts.

Yes

Step 8

Confirm that the fault has been fixed.

4.4.4.10 Tire Wear Indicator

FE04-1020b

Original tires have embedded tread wear indicator, which indicates when the tires need to be replaced. When the tire tread becomes
shallow, these marks appear as bands. When three out of six indicators appear, it is recommended to replace the tire.

4.4.4.11 Radial Tire Deviation Correction

1. Fault Definitions:

When the vehicle is driving a straight line at a certain speed, without external force on the steering wheel, the vehicle deviates from
the original direction to the left or the right direction.

2. Vehicle Deviation Benchmark :

A. When the vehicle is driving a straight line at a certain speed, it is necessary to impose force on the steering wheel to prevent its

clockwise or counterclockwise rotation.

B. When the vehicle is driving a straight line at a certain speed, release the steering wheel, the vehicle deviates to the left or the

right direction (usually travel 100 m (3,940 in) from the original travel direction 1 m (39.4 in) or above).

Note

Before correct the deviation, check the following basic items
A. Check whether the front and rear brakes are dragging.

B. Check on the same suspension, whether the tire wear difference is too great.

C. Check on the same suspension, whether the tire pressure difference is too great.

If there is any abnormal item, please adjust to the normal state before road testing the vehicle. Confirm whether the
fault has been excluded.

3. Correction Procedure:

Warning!

Please road test the vehicle safely and comply with all traffic laws and regulations. Do not try operation that might
jeopardize the vehicle control. A breach to the safety precautions can result in serious personal injury and damage to
the vehicle.

Step 1

Road test the vehicle to determine whether the vehicle is deviating?

Suspension System

No

Explain to customers the definition of
deviation. According to different road
conditions, vehicles may be deviating in a
short time, giving a false impression

Yes

Step 2

Check whether the toe value is normal?

No

Readjust the vehicle front wheel toe value. If
necessary, adjust the wheel positioning.

Yes

Step 3

Check whether the vehicle wheel positioning parameters are the specified value?

No

Carry out the wheel positioning.

Yes

Step 4

Compare all positional parameters with specifications in the table. Complied with specifications?

No

Go to step 10

Yes

Step 5

Rotate tires.

(a)

Rotate the left front wheel assembly and the left rear wheel
assembly.

(b)

Road test the vehicle.

Whether the vehicle is still deviating?

No

System normal

Yes

Step 6

Rotate tires.

(a)

Rotate the left front wheel assembly and the left rear wheel
assembly and replace the left front tire.

(b)

Road test the vehicle.

Whether the vehicle is still deviating?

No

System normal

Yes

Step 7

Rotate tires.

(a)

Rotate the right front wheel assembly and the right rear wheel
assembly.

(b)

Road test the vehicle.

Step 8

Rotate tires.

(a)

Rotate the right front wheel assembly and the right rear wheel
assembly and replace the right front tire.

(b)

Road test the vehicle.

Yes

Step 9

Return to the diagnosis starting point.

Step 10

Check the axle, suspension system components, for existence of bending damage?

No

Go to step 1

Yes

Step 11

Adjust the axle. If necessary, replace the damaged parts to confirm The fault has been fixed..
