Axial clearance checking

1

Park vehicle in a flat and leveled ground where you can execute tasks securely.

2

Attach dial indicator (2) magnetic base (1) in the steering arm or in any other fixed vehicle part and position indicator rod in the terminal end cover (3).

3

With a running engine, steer steering wheel slightly to the left and to the right, to create an actuation force on the steering and link bar.

4

Measurement in the indicator cannot exceed 2 mm.

If ball stud clearance measured in the indicator is smaller than 0.15 mm, checking rotating torque is not mandatory.

Rotating torque checking

To check this, it is necessary to remove steering bar.

1

Assemble nut (6) in the ball terminal (3) and block it with cotter pin, if it exists.

2

Fit an appropriate socket (5) together with torque wrench (4) in the nut (6).

3

Turn terminal ball stud (3) with a rotation of approximately 5 turns per minute, observing torsion moment indicated in the torque wrench display.

Torsion moment should be above 1 Nm. If torsion moment measured is below 1 Nm, ball terminal should be replaced.

Ball stud maximum permitted torsion moment is 21 Nm.
