PINION TOTAL ROTATION TORQUE CHECK
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.

AB
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 (2.6 − 7.0 in-lb)
Torque fluctuation: 0.4N
⋅ m (1.76 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
).
TIE-ROD OSCILLATING TORQUE CHECK
.
AC000997
1. Swing the tie-rod ten times strongly.
2. Measure the oscillating resistance (oscillating torque) using
a spring scale as shown in the figure with the tie-rod end
facing downward.
Standard value:
5
− 18 N⋅ m (22 − 80 in-lb)
{1.5
− 4.9 N⋅ m (13.2 − 43.4 in-lb) }
3. If the measurement is greater than the standard value,
replace the gear housing (Refer to
).
4. If the measurement value is below the standard value,
check the ball joint for looseness or scraping feeling. If the
ball joint swings smoothly, it is judged to be usable.
