STEERING GEAR TOTAL PINION
TORQUE CHECK
CAUTION
When holding the steering gear in a vice, secure
its mounting positions. If it is secured in any
other place, the gear housing may become
deformed or damaged.
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: 0.7 − 1.6 N⋅m
1300, 1600(Comfort): 0.8 − 2.1
1600(Sport), 2000: 0.7 − 2.1
[Change in torque: 0.6 N⋅m or less]NOTE: When measuring, remove the bellows from
the rack housing. Measure the pinion torque through
the whole stroke of the rack.
If the measured value is not within the standard
range, first adjust the rack support cover, and then
check the total pinion torque again.
If the total pinion torque cannot be adjusted to within
the standard range by adjusting the rack support
cover, check the rack support cover, rack support
spring, rack support and replace any parts if
necessary.
TIE ROD SWING RESISTANCE CHECK
1. Give 10 hard swings to the tie rod.
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.
TIE ROD END BALL JOINT DUST COVER
CHECK
1. Check the dust cover for cracks or damage by
pushing it with your finger.
2. If the dust cover is cracked or damaged, replace
the tie rod end (Refer to P.37-27).
NOTE: Cracks or damage of the dust cover may
damage the ball joint. If it is damaged during
service work, replace the dust cover (Refer to
P.37-36).

•MB991621: Piston Driver
4. Turn the rack support cover 30° anticlockwise.
5. Use the special tool to hold the rack support
cover, and then tighten the lock nut to 59 ± 10
N⋅m.
>>K<< TOTAL PINION TORQUE
ADJUSTMENT
CAUTION
•Be sure there is no ratcheting or catching
when operating the rack towards the shaft.
•Measure the total pinion torque through the
whole stroke of the rack.
1. Using special tool preload socket (MB991006),
rotate the pinion shaft at the rate of one rotation in
4 to 6 seconds to check the total pinion torque and
the change in torque.
Standard value:
Total pinion torque: 0.8 − 2.1 N⋅m <1300,
1600(Comfort)>
[Change in torque: 0.6 N⋅m or less]
Total pinion torque: 0.7 − 2.1 N⋅m <1600(Sport),
