(d) Hook the front wheel hub with the spring-tension meter
and pull the spring-tension meter slowly in the tangential
direction of this spot.
The reasonable range of tension force: (16-33)N.
Remark: if the tension force is larger or smaller of the reason-
able range, screw up the nuts again until the tension force falls
within the reasonable range.
(e) Measure the bouncing value of the front brake disc,
which should not be larger than 0.11mm.

Steering Knuckle
Disassembly of Steering Knuckle
1. Take apart the brake caliper, the front wheel hub and the
front brake disc.
2. Take apart the front brake shell:
(a) Tear down the two bolts (M8X16).
(b) Tear down the two split pins, grooved nuts, washer and
bolts that connect the steering knuckle arm.
3. Tear down the steering knuckle
(a) Support the lower arm with jack;
(b) Tear down the two split pins and the grooved nuts
(c) Disconnect the steering knuckle from the upper and
lower ball studs and take apart it.
Inspection on Steering Knuckle
Check the steering knuckle
Check the steering knuckle with the dye penetration agent to
see whether the steering knuckle has a crack or not.
If the crack is found, the steering knuckle is required to be
changed.

Mount the steering knuckle
1. Mount the steering knuckle
(a) Support the lower arm of the steering knuckle with a jack.
(b) Mount the steering knuckle on the lower ball stud and
screw on the nuts.
(c) Press the upper arm to mount on the steering knuckle and
screw on the nuts.
(d) Screw up the nuts of the upper ball stud according to the
specified torque.
Fastening torque(100-120)Nm
(e) Screw up the nuts of the lower ball stud according to the
specified torque.
Fastening torque(98-118)Nm
(f) Mount on the split pin between the upper and lower ball
studs.
2. Mount the steering knuckle arm and the front brake shell;
(a) Screw up the two bolts of M8X16.
Fastening torque(25-28)Nm
(b) Screw up the two bolts and groove nuts (M12X67) to the
specified torque.
Fastening torque(98-118)Nm
(c) Mount on the two split pins.
In case the pin hole in the ball stud are not in alignment with
the groove nut, adjust the fastening torque and the rotating
angle under the condition that satisfying the minimum torque,
so as to ensure the torque falls within the specified range, if
cannot, mount the split pin with the minimum torque beyond
the range
3. Mount the front wheel hub and the front brake disc.
4. Check the Alignment of Front Wheel.

Ball stud
Inspection on Ball Stud
1. Check the lower ball stud to see whether it is excessively
loose or not.
(a) Prop up the front of the vehicle with jack and then support
it with the bracket.
(b) Tread down the brake pedal after verifying that the front
wheel are in straight line.
(c) Move the arm vertically to check the lower ball stud to see
whether the clearance is overlarge.
Max vertical clearance : 0.5mm
2. Check the upper ball stud to see whether it is over-loose.
Move the wheel vertically to check whether the clearance of
the ball stud is over large.
3. Check the rotating performance of ball stud
(a) Take apart the ball stud.
(b) Shake the ball stud several times forward and backward
before mounting on the nut, as shown in the drawing.
(c) Rotate the nut continuously with a torsion meter, which
rotates the nut round per 2 to 4 seconds, and read the
reading of the torsion meter after the fifth round.
Fastening torque (running)
Lower ball stud: (0.1-4)Nm
Upper ball stud: (0.1-4)Nm
Disassembly of Ball Stud
