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.

Torsion Rod Spring
Dismantle of Torsion Rod Spring
1. Use the jack to raise up the frame and support it with the
bracket.
2. Take apart the locking nuts to measure the length of the
projecting end of the bolts, as shown in the drawing.
Remark: This measuring value can be referred when adjusting
the chassis ground clearance.
3. Take apart the dust cover.
4. Loosen the regulating nut until there is no tension on the
torsion rod spring.
5. Take apart the torsion arm, torsion rod spring and the
torsion regulating arm.
(a) Tear down the mounting nuts of the torsion rod arm.
(b) Take apart the torsion regulating arm from the adjusting
bolt, the torsion regulating arm should be taken apart with
the torsion rod spring and the torsion rod arm together.
