ON-VEHICLE SERVICE
POWER STEERING37-16
WARNING
•If the vehicle continues to be driven after
the collision absorbing mechanism has
operated, the steering column shaft may
be damaged while it is in use.
•If there is a slack in the one-way capsule,
do not attempt to repa ir it but replace the
steering column shaft assembly.
Inspection Procedure
1. Remove the lower and upper column covers.
CAUTION
Do not release the tilt lever until the steering col-
umn has been installed to complete this inspec-
tion procedure.
2. Ensure that the tilt lever is in the lock position.
NOTE: If not, place the tilt lever in the lock posi-
tion.

One way capsule
4. Hold the one way capsule as shown, and then try
to lock them. If there is a slack in either of the
capsules, replace the steering column shaft
assembly.
NOTE: When installing a new steering column
shaft assembly, place the tilt lever in the lock posi
-
tion, if it is not in place.
CAUTION
•Be careful that nothing is pinched between
the one-way capsules and the body.
•Do not release the tilt lever until the steering
column has been installed to complete this
inspection procedure.
5. If no problem is found during the inspection, tighten the steering column mounting bolts to the
specified torque.
Tightening torque: 12 ± 2 N⋅m

CAUTION
•When reusing the steering column, do not
release the tilt lever until the steering column
shaft has been installed.
•When the steering column is replaced, do not
release the tilt lever until it has been installed.
Do not remove the tilt lever fixing band until
the installation has completed.
•When installing the steering column, do not
leave it fixed temporarily at only one point
and make sure the column shaft is not shaken
strongly. If you fail to do, the collision absorb
-
ing mechanism at the column shaft mounting
location may be damaged.

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.
AC000996 AC
MB991006
Using special tool preload socket (MB991006), rotate
the pinion gear at the rate of one rotation in approxi
-
mately 4 to 6 seconds to check the total pinion
torque.
Standard value:
0.8 − 2.1
0.7 − 2.1
[Change in torque: 0.6 N⋅m or less]
Page 255 of 800
POWER STEERING GEAR BOX AND LINKAGE
POWER STEERING37-25
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 neces
-
sary.
TIE ROD SWING RESISTANCE CHECK
1. Give 10 hard swings to the tie rod.
AC000997
2. Measure the tie ro d swin g resist ance [tie rod
swing to rque] with a spring bala n ce.
St andard va lue: 8 − 27 N [1.5 − 4.9 N⋅m]
3.If the measu r ed value exceeds the st a ndard
value , replace the tie rod.
4. If the measured value is below the st a ndard valu e,
th e tie rod can be re-use d if it swings smo o thly
wit hout e xce ssive play .

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

CAUTION
When adjusting, set at the highest value of the
standard value range.
NOTE: If the total pinion toque cannot be adjusted
to the standard value within the specified return
angle, check the rack support cover components
and replace any parts if necessary.
2. If the total pinion torque or the change in torque is outside the standard value, move the rack support
cover 0
