CAUTION
•Do not remove the tie rod end nut from the
ball joint. Loosen it and use special tool to
avoid possible damage to the ball joint
threads.

2. Turn the bolt and knob as necessary to make the jaws of special tool parallel, tighten the bolt by
hand and confirm that the jaws are still parallel.
NOTE: When adjusting the jaws in parallel, make
sure the knob is in the position shown in the fig
-
ure.
3. Tighten the bolt with a wrench to disconnect the tie rod end.

4. Move the ball joint stud several times and install
the nut on the stud. Using special tool preload
socket (MB990326), measure the ball joint turning
torque.
Standard value: 0.5 − 2.5 N⋅m
5. If the turning torque exceeds the standard value, replace the tie rod end.
6. If the turning torque is under the standard value, check the ball joint for axial play or ratcheting. If
no axial play or ratcheting, the ball joint can be
re-used.
CAUTION
Always use a new ball joint nut as it is a self-lock-
ing nut.
7. Install the tie rod end to the knuckle, then tighten a new self-locking nut to the specified torque.
Tightening torque: 25 ± 5 N⋅m
STATIONARY STEERING EFFORT CHECKM1372001700332
1. With the vehicle stopped on a flat and paved
surface, turn the steering wheel to the straight
ahead position.
2. Start the engine and set the engine idle speed.
Standard value: 750 ± 100 r/min
ACX01122 AB
3. Attach a spring balance to the outer
circumference of the steering wheel and measure
the steering force required to turn the steering
wheel from the straight ahead position to the left
and right (within a range of 1.5 turns). Also check
to be sure that there is no significant change in
the required steering effort.
Standard value:
Steering effort: 29 N or less
Fluctuation allowance: 5.9 N or less
4. If the measured value exceeds the standard value, check and adjust the related parts.
