Ball pin
Check 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
4N
m
Upper ball pin 0.1
4N
m
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
Installation of ball pin
1. Install the upper ball pin on the upper arm
Tightening force: 78
5N
m
2. Install the lower ball pin on the lower arm
Tightening force: 140
10N
m
3. Install the steering knuckle and front hub assembly
(Refer to section “Front Hub and Steering Knuckle”)
Torsion bar spring
Disassembly of torsion bar spring
1. Make the assembly mark on the torsion bar spring,
torsion base and adjusting arm
2. Measure the length A of extension section of bolt
according to the length shown in figure.
Remarks: The measuring value is for reference when adjust the
ground clearance of chassis.
3. Loose the adjusting bolt until the torsion bar spring
has not the tension.
4. Remove the fixed arm and torsion bar spring
Installation of torsion bar spring
Remarks: There are the L and R indication marks, which must not
be exchanged on the rear end of the torsion bar spring. Mark L
means the left while R for right
1. For reused torsion bar spring
a. Cost the spline of torsion bar spring with grease thin.
b. Align the assembly mark and install the torsion bar spring on the
torsion bar.
c. Align the assembly mark and install the adjusting arm on the
torsion bar spring.
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
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).
