Ball pin
Inspection of ball pin
1. Check the lower ball pin for loose
a. Raise the front of the car by jack and support it by the frame.
b. Ensure the front wheel is in straight advancing position and
step down the brake pedal.
c. Move the arm upwardly and downwardly; check the
clearance of lower ball pin.
Max. vertical clearance: 0mm
2. Check the upper ball pin for loose;
move the wheel upwardly and downwardly and check the gap of
upper ball pin.
Max. vertical clearance: 0mm
3. Check the rotation of ball pin
a. Remove the ball pin.
b. Shown as figure, shake the ball pin stud forwardly and
backwardly for several times before install the nut.
c. Rotate the nut continuously by torsion meter and 2-4s for a
cycle; record the readout of torsion meter in the fifth cycle.
tightening torque (for rotary):
lower ball pin 0.1
4Nm
upper ball pin 0.1
4Nm
Disassembly of ball pin
1.Take down the steering knuckle and front wheel hub assy.

d. Tighten the adjusting bolt to make the extension length of the bolt
equal to the length before remove.
2. For new torsion bar spring
a. Remove the wheel.
b. Coat thin grease on the spline of the torsion bar spring.
c. Install the torsion bar spring on the torsion bar base.
d. Lower the lower arm to the lower limitation position; install the
adjusting arm in the torsion bar spring with the angle that the
adjusting bolt just can be screwed on the upper adjusting block.
e. Tighten the adjusting bolt to the specified torque.
Nut tightening limitation: A is about 30-35mm; if A>
35mm, then it is adjusted through height of adjusting arm.
f. Install the wheel; remove the bracket; bounce the vehicle for
several times to make the suspension enters into the stable
status.
g. Rotate the adjusting bolt and adjust the ground clearance of
chassis (Refer to 4-Wheel Alignment).

5. Install the torsion bar spring
(Refer to “Torsion Bar Spring”)
6. Tighten the nut of front shaft of lower arm to
specified torque
a. Install the wheel, remove the bracket and bounce the vehicle for
several times to make the vibration damper enters into the
stable status.
b. Align the assembly mark and tighten the nut to specified torque.
Tightening force: 240
20Nm
7. Check the wheel alignment parameter
(Refer to 4-Wheel Alignment)

Connect the copper gasket seal and tighten the hollowbolttospecified
torque.
Tightening force: 50
5Nm
6. Discharge the air in front brake system
(refer to relevant chapter)
Remarks: It must discharge the air in the rear brake system if
disassemble the right upper arm.
7. Check the brake fluid for leakage
8. Tighten the upper arm front shaft nut to the specified
torque
Install the wheel, remove the bracket and bounce the vehicle for
several times to make the vibration damper enters into the stable
status.
9. Check the wheel alignment parameter
(Refer to 4-Wheel Alignment)

Disassembly of ball pin
1. Remove the steering knuckle and front hub assembly
(Refer to section “Front Hub and Steering Knuckle”)
2. Remove the lower ball pin form the lower arm
3. Remove the upper ball pin from the upper arm

d. Tighten the adjusting bolt and make the extension length of the
bolt equal to the value before disassembly.
2. For new torsion bar spring
a. Remove the wheel.
b. Coat the spline of torsion bar spring with thin grease.
c. Install the torsion bar spring on the torsion bar base.
d. Lower the lower arm to the lower limitation position; install
the adjusting arm in the torsion bar spring with the angle that
the adjusting bolt just can be screwed on the upper adjusting
block.
Remarks: It can repeat for several times until proper when
adjust the angle.
e. Tighten the adjusting bolt to the specified torque.
Nut tightening limitation: A is about 20-35mm; if A>35mm,
then it is adjusted through height of adjusting arm.
f. Install the wheel; remove the bracket; bounce the vehicle for
