4. Adjust the preload
(a) Mount on the steering knuckle nut and screw up them
according to the specified torque.
Tighten torque: (100-120)N
m
(b) Run the front wheel hub about 1/4-1/3 round, and seat the
bearing.

The nuts should be retightened until falls within the suitable
range if the tension force is overlarge or over small.
(f) Check the bearing and ensure that the clearance, which is
not larger than 0.05 mm, is not excessive.

Inspection on Ball Stud
1. Check the lower ball stud to see whether it is excessively
loose:
(a) Raise the vehicle with a jack and then support it with the
bracket.
(b) Press down the brake pedal after verifying that the front
wheel is straightly forward.
(c) Move the arm vertically to check whether the clearance
of lower ball stud is over large.
(Max vertical clearance): 0.5 mm
2. Check whether the upper ball stud is loose excessively;
Move the wheel vertically to check whether the clearance of
the ball stud is over large.
(Max vertical clearance): 0.5 mm
3. Check the rotating performance of the ball stud:
(a) Tear down the ball stud;
(b) Shake the ball stud column several times before mount-
ing on the nut, as shown in the drawing.
(c) Rotate the nut continuously with the torsion meter at the
speed of one round each 2 to 4 seconds, read the meter
reading at the fifth round.
