1. Using special tool preload socket (MB991006),
rotate the pinion gear at the rate of one rotation in
approximately 4 to 6 seconds to check the total
pinion torque.
Standard value:
Total rotation torque 0.8
− 1.8 N⋅m
Torque fluctuation 0.49 N
⋅m or less
NOTE: Remove the bellows from the rack hous-
ing before measuring.
NOTE: Measure the total rotation torque by turn-
ing the special tool left and right 180
°
from the
neutral position.
2. If the standard values are not met, adjust the
pinion total rotation torque.
3. In case the adjustment is impossible, disassemble
and check the components, and repair if
necessary.
TIE ROD SWING RESISTANCE CHECK
1. Give 10 hard swings to the tie rod.
AC000997
2. Measure the tie rod swing resistance [tie rod
swing torque] with a spring balance.
Standard value: 8
− 27 N [1.5 − 4.9 N⋅m]
3. If the measured value exceeds the standard
value, replace the tie rod.
4. If the measured value is below the standard value,
the tie rod can be re-used if it swings smoothly
without excessive play.
