6. Check whether or not the hydraulic pressure is the standard value when no-load conditions are
created by fully opening the shut-off valve of the
pressure gauge.
Standard value: 0.2 − 0.7 MPa
7. If it is not within the standard value, the probable cause is a malfunction of the oil line or steering
gear, so check these parts and repair as
necessary.
8. Turn the steering wheel all the way to the left or right; then check whether or not the retention
hydraulic pressure is the standard value.
Standard value: 8.8 − 9.5 MPa
9. If not the standard value, overhaul the steering gear. Remeasure fluid pressure.
10. Remove the special tools, and then tighten the
pressure hose to the specified torque.
Tightening torque: 57 ± 7 N⋅m
11. Bleed the system (Refer to P.37-14).

WARNING
Before removing the steering gear, refer to GROUP 52B, Service Precautions (P.52B-5) and
Air Bag Module and Clock Spring (P.52B-194). Centre the front wheels. Failure to do so may
damage the SRS clock spring and render the SRS system inoperative, risking serious injury.
Pre-removal Operation
•Power Steering Fluid Draining (Refer to P.37-13.)
Post-installation Operation
•Check the dust cover for cracks or damage by pushing it
with your finger.
•Power Steering Fluid Supplying (Refer to P.37-13.)
•Power Steering Fluid Line Bleeding (Refer to P.37-14.)
•Checking Steering Wheel Position with Wheels Straight
Ahead.
•Front Wheel Alignment Adjustment (Refer to GROUP 33,

O RQUE 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.
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]

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 .

CHECK
1.Check t he dust co ver f o r cracks or da mage by
p u shing it with your finger .
2.If the du st cover is cracked o r damaged, repla c e

P.37-26).
NOTE: Cracks or dama ge of t he dust co ver may
