STEERING WHEEL FREE PLAY CHECK

M1372001000559

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.

Maximum limit: 30 mm or less

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.37-22

) and check

the total pinion torque (Refer to

P.37-26

STEERING ANGLE CHECK

M1372001101634

CAUTION

• When the steering angle is adjusted, the cali-

bration of steering wheel sensor must be per-
formed. (Refer to GROUP 35C, On-vehicle
Service ). <Vehicles with ASTC>

AC000756AB

1. Place the front wheel on a turning radius gauge

and measure the steering angle.

Standard value:

NOTE: *: Difference between right and left wheels
must be 2

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: 0

− 5 mm

Toe-angle (per wheel): 0

° 00' − 0°12'

Lock nut

Clip

3. Adjust the toe-in by undoing the clip and lock nut,

and 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.

4. Tighten the lock nut to the specified torque, and

tighten the bellows by the clip.

Tightening torque: 93

± 15 N⋅m

5. Recheck the steering angle.

TIE ROD END BALL JOINT DUST COVER
CHECK

M1372008600444

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 (Refer to

P.37-26

NOTE: If the dust cover is cracked or damaged,
the ball joint could be damaged.

CAUTION

• Do not remove the nut from ball joint. Loosen

it and use the special tool to avoid possible
damage to the ball joint threads.

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 fig-
ure.

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
starting torque.

Standard value: 1.47

− 2.94 N⋅m

5. If the starting torque exceeds the standard value,

replace the tie rod end (Refer to

P.37-26

6. If the starting 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-lock-
ing nut.
7. Install the tie rod end to the knuckle, then tighten a

nut to the specified torque.

Tightening torque: 40

± 4 N⋅m

STATIONARY STEERING EFFORT CHECK

M1372001700644

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 allow it to idle.

ACX01122 AB

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: 39.2 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.

STEERING WHEEL RETURN TO CENTRE
CHECK

M1372001800470

Conduct a road test:

1. Make both gradual and sudden turns and see by

your own feeling that the steering effort and
returnability have no difference between the left
and right turns.

ACX01130AB

70˚

2. At a vehicle speed of approximately 35 km/h, turn

the steering wheel 90

°, hold a few seconds, then

release. If the steering wheel then returns 70

° or

more, the return can be judged satisfactory.
NOTE: There will be a momentary feeling or
heaviness when the wheel is turned quickly, but
this is not abnormal. (Oil pump discharge amount
is especially apt to be insufficient during idling.)

FLUID LEVEL CHECK

M1372002000433

1. Park the vehicle on a flat, level surface.
2. Start the engine, and then turn the steering wheel

several times to raise the temperature of the fluid
to approximately 50

− 60°C.

3. With the engine running, turn the wheel all the

way to the left and right several times.

ACX01131

With engine running

With engine stopped

Fluid level change: Within 5 mm

4. Check the fluid in the oil reservoir for foaming or

milkiness. Check the difference of the fluid level
when the engine is stopped, and while it is
running. If the change of the fluid level is 5 mm or
more, air bleeding should be done (Refer to
