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: 0.8
− 2.1 N⋅m
[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.
