CAUTION
• Loosen the jam nut (tie-rod end connection) from the
ball joint, but do not remove here. Use the special tool.
• To prevent the special tool from dropping off, suspend
it with a cord.
1. Install special tool MB991897 or MB992011 as shown in the
figure.
2. Turn the bolt and knob to make the special tool jaws parallel,
then hand-tighten the bolt. After tightening, check that the
jaws are still parallel.
NOTE: To adjust the special tool jaws to be parallel, set the
orientation of the knob as shown in the figure.
3. Unscrew the bolt to disconnect the ball joint.

PINION TOTAL ROTATION TORQUE CHECK
Required Special Tools:
• MB991006: Preload Socket
CAUTION
Secure the steering gear and linkage to the special mount-
ing point. Fixing the steering gear and linkage to another
point could deform or damage the gear housing.
.
1. Using the special tool preload socket (MB991006) to rotate
the pinion at a rate of one turn per 4 to 6 seconds, and then
measure the pinion total rotation torque.
Standard value:
Total rotation torque: 0.6 − 1.6 N⋅ m (5.3 − 14.2 in-lb)
Torque fluctuation: 0.4N⋅ m (3.5 in-lb) or less
NOTE:
.
•
During measurement, remove the bellows from the gear
housing.
•
Rotate the pinion by 180
°
in left and right directions from
the neutral position, and measure the pinion total rotation
torque.
2. If the measurement value is outside the standard value,
replace the gear housing (Refer to
).
