WHEEL ALIGNMENT
Description
In general, the wheel alignment has following 6 parameters:
1. Check front wheel camber
2. Check front wheel toe-in
3. Check kingpin caster
4. Check kingpin inclination
5. Check rear wheel camber
6. Check rear wheel toe-in
If following components have been removed, installed or replaced, check and perform wheel alignment
procedures:
Front control arm assembly
Front control arm ball pin assembly
Front steering knuckle
Front shock absorber assembly
Steering gear and steering tie rod
Drive shaft
Front sub frame welding assembly
Rear suspension lower swing arm assembly
Rear sub frame assembly
Rear trailing arm assembly
Specifications
Specifications (parameters standard for four-wheel alignment)
CAUTION
Be sure to perform wheel alignment procedure according to operating instructions of four-wheel
alignment device.
Periodic maintenance and service for four-wheel alignment device should be performed.

Problem Symptoms Table
HINT:
Use the table below to help determine the cause of the problem symptoms. Check each suspected area in
sequence. Repair or replace the faulty components, or adjust them as necessary.
Inspection before Wheel Alignment
1. Vehicle is in unloaded state.
2. Use a lifter to support and raise vehicle to proper height.
3. Check hub bearing for excessive clearance, and replace hub bearing as necessary.
4. Check suspension components, steering tie rod and ball pin for wear, deformation or damage. Replace the
malfunctioning part as necessary.
5. Check if shock absorber assembly operates normally.
6. Check if tire pressure is within the specified range and adjust it to specified pressure as necessary.
Standard Inflation Pressure of Cold Tire (kPa)
7. Check the rim and tire.
a. Visually check rim and tire for scratches, wear or damage.
b. Perform wheel dynamic balance procedures (

Front Wheel Toe-in
Incorrect front wheel toe-in will cause wheel pull and abnormal tire wear. Check and adjust front wheel toe-in
as necessary.
Adjust the length of steering tie rod to the specified valve if front wheel toe-in is not within the tolerance due to
other reasons.
Specified Value for Front Wheel Toe-in
Inspection
1. Perform inspection with four-wheel alignment device (perform inspection procedures referring to operating
instructions for four-wheel alignment device).
2. Manual check:
a. Park vehicle on level ground, check if front tire pressure is within the specified range and adjust it to
specified value as necessary.
b. Place marks on the center position in front of front
wheels, and measure distance A between marks with
a tape measure.
c. Push vehicle to rotate wheels 180°, and measure
distance B between marks with tape measure when
the marks are turned to the rear of wheels.
d. Calculation method: front wheel toe-in = A - B ≤ 1 mm

Adjustment
1. Make adjusting preparation for wheel alignment according to the requirement of tester.
2. Loosen the steering tie rod locking nut (1) and elastic
jacket snap ring (2), and turn the tie rod to adjust length
according to the requirement until front wheel toe-in
reaches the specified value.
3. Tighten the steering tie rod locking nut, reinstall the elastic jacket snap ring. Check if locking nut is
tightened in place and if jacket position is correct.
(Tightening torque: 55 ± 5 N·m)
4. After adjusting front wheel toe-in, check the steering wheel for eccentricity. If necessary, loosen the
steering wheel locking nut and adjust the steering wheel to horizontal position, and then tighten the
steering wheel locking nut to the specified torque.
(Tightening torque: 35 ± 5 N·m)
