CAUTION

When holding the steering gear box assembly in a vice,
secure its mounting positions. If it is secured in any other
places, the gear housing may become deformed or
damaged.
Using special tool MB990228 or MB991006, rotate the pinion
gear at the rate of one rotation in approximately 4 to 6 seconds
to check the total pinion torque.

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.
