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
