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.37-13).
POWER STEERING PRESSURE SWITCH
CHECK
M1372007200324
1. Disconnect the pressure hose from the oil pump,
and then connect the following special tools.
•MB990662: Power Steering Oil Pressure Gauge
•MB991548: Power Steering Oil Pressure Gauge
Adapter (pump side)
•MB991549: Power Steering Oil Pressure Gauge
Adapter (hose side)2. Bleed air, and then turn the steering wheel several
times while the vehicle is not moving so that the
temperature of the fluid rises to approximately 50
− 60°C.
3. The engine should be idling.
4. Disconnect the connector for the oil pressure
switch, and place an ohmmeter at the switch.
5. Gradually close the shut-off valve of the pressure
gauge and increase the hydraulic pressure, then
check whether or not the hydraulic pressure that
activates the switch is the standard value.
Standard value: 1.5 − 2.0 MPa
6. Gradually open the shut-off valve and reduce the
hydraulic pressure; then check whether or not the
hydraulic pressure that deactivates the switch is
the standard value.
Standard value: 0.7 − 2.0 MPa
7. Remove the special tools, and then tighten the
pressure hose to the specified torque.
Tightening torque: 57 ± 7 N⋅m
8. Bleed the system (Refer to P.37-13).
TIE ROD END BALL JOINT DUST COVER
CHECK
M1372008600262
1. Press the dust cover with your finger to check
whether the dust cover is cracked or damaged.
2. If the dust cover is cracked or damaged, replace
the tie rod end.
NOTE: If the dust cover is cracked or damaged,
the ball joint could be damaged.
STEERING COLUMN SHAFT ASSEMBLY
SHOCK ABSORBING MECHANISM
CHECK
M1372013500090
If a collision accident occurs or severe impact is
applied on the steering wheel, the collision energy
absorbing mechanism may have operated. Once the
mechanism has operated, it will be inoperative even
it has suffered no apparent damage. Determine if the
steering column shaft can be reused by the following
procedure. If the collision energy absorbing
mechanism has already operated, replace the
steering column shaft assembly.
If any excessive radial free play on the steering
wheel is found with the tilt lever in the lock position,
always check the steering shaft assembly.

WARNING
Before removing the steering gear, refer to GROUP 52B, Service Precautions (P.52B-5) and
Air Bag Module and Clock Spring (P.52B-210). Centre the front wheels. Failure to do so may
damage the SRS clock spring and render the SRS system inoperative, risking serious injury.

steering joint cover to the steering gear.
INSPECTIONM1372011000237
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).
