REAR WHEEL ALIGNMENT CHECK AND
ADJUSTMENT
M1341011000372
Measure wheel alignment with an alignment
equipment on level earth.
The rear suspension, wheels, and tyres should be
serviced to the normal condition prior to wheel
alignment measurement.
CAMBER
Standard value: -0° 40' ± 30' (Left/right
deviation within 30')
CAUTION
Never subject the wheel bearings to the vehicle
load when the rear wheel hub nuts (self-locking
nuts) or special tool wheel alignment gauge
attachment (MB991014) are loosened.
NOTE:
For vehicles with aluminium wheels, attach the
camber/caster/kingpin gauge to the trailing arm
spindle by using special tool wheel alignment gauge
attachment (MB991014). Tighten the special tool to
the same torque 175
± 25 N⋅m as the rear wheel hub
nut (self-locking nut). MB990947 Lower arm bushing arbor Trailing arm bushing

STEERING WHEEL FREE PLAY CHECKM1372001000311
1. With the engine running (hydraulic operation), set
the front wheels straight ahead.
2. Measure the play on the steering wheel
circumference before the wheels start to move
when slightly moving the steering wheel in both
directions.
Limit: 30 mm
3. When the play exceeds the limit, check for the
play on the steering shaft and steering linkage
connection. Correct or replace.
4. If the free play still exceeds the limit value, set the
steering wheel straight ahead with the engine
stopped. Load 5 N towards the steering wheel
circumference and check the play.
Standard value (steering wheel play with the
engine stopped): 10 mm or less
5. If the play exceeds the standard value, remove
the steering gear (Refer to P.37-24) and check
the total pinion torque (Refer to P.37-27).
STEERING ANGLE CHECKM1372001100374
1. Place the front wheel on a turning radius gauge
and measure the steering angle.
Standard value:
2. If the steering angle is not within the standard
value, adjust the toe-in as follows.
Standard value:
at the centre of tyre tread: 1 ± 2 mm
Toe angle (per wheel): 0°03' ± 06'
3. Loosen the lock nut, and unclip the bellows.
4. Adjust the toe-in by turning the left and right tie
rod turnbuckles by the same amount (in opposite
directions).
NOTE: The toe will move out as the left
turnbuckle is turned toward the front of the vehicle
and the right turnbuckle is turned toward the rear
of the vehicle.
5. Tighten the lock nut to the specified torque, and
tighten the bellows by the clip.
Tightening torque: 40 ± 5 N⋅m
6. Recheck the steering angle.

TIE ROD END BALL JOINT TURNING
TORQUE CHECK
M1372001500297
CAUTION
•Do not remove the tie rod end nut from the
ball joint. Loosen it and use special tool to
avoid possible damage to the ball joint
threads.
•Hang special tool with cord to prevent it from
falling.
1. Install special tool ball joint remover (MB991897)
as shown in the figure.
2. Turn the bolt and knob as necessary to make the
jaws of special tool parallel, tighten the bolt by
hand and confirm that the jaws are still parallel.
NOTE: When adjusting the jaws in parallel, make
sure the knob is in the position shown in the
figure.
3. Tighten the bolt with a wrench to disconnect the
tie rod end.4. Move the ball joint stud several times and install
the nut on the stud. Using special tool preload
socket (MB990326), measure the ball joint turning
torque.
Standard value: 0.5 − 2.5 N⋅m
5. If the turning torque exceeds the standard value,
replace the tie rod end.
6. If the turning torque is under the standard value,
check the ball joint for axial play or ratcheting. If
no axial play or ratcheting, the ball joint can be
re-used.
CAUTION
Always use a new ball joint nut as it is a
self-locking nut.
7. Install the tie rod end to the knuckle, then tighten a
new self-locking nut to the specified torque.
Tightening torque: 25 ± 5 N⋅m
STATIONARY STEERING EFFORT CHECKM1372001700332
1. With the vehicle stopped on a flat and paved
surface, turn the steering wheel to the straight
ahead position.
2. Start the engine and set the engine idle speed.
Standard value: 1000 ± 100 r/min
3. Attach a spring balance to the outer
circumference of the steering wheel and measure
the steering force required to turn the steering
wheel from the straight ahead position to the left
and right (within a range of 1.5 turns). Also check
to be sure that there is no significant change in
the required steering effort.
Standard value:
Steering effort: 29 N or less
Fluctuation allowance: 5.9 N or less
4. If the measured value exceeds the standard
value, check and adjust the related parts.

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.
