STEERING WHEEL FREE PLAY CHECK

M1372001000582

1. With the engine running, set the front wheels

straight ahead.

AC000987

2. Measure the play on the steering wheel

circumference before the tyre & wheel 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 play still exceeds the specification after

inspecting item 3, inspect the steering gear &
linkage assembly, and replace as necessary
(Refer to

P.37-101

).

STEERING ANGLE CHECK

M1372001100857

1. Adjust toe-in (Refer to GROUP 33, On-vehicle

Service

− Front Wheel Alignment Check and

Adjustment

P.33-5

).

AC000756AB

2. Place the front wheel on a turning radius gauge

and measure the steering angle.

Standard value:

TIE ROD END BALL JOINT TURNING
TORQUE CHECK

M1372001500651

BALL JOINT LOOSENESS CHECK

1. Raise the vehicle.
2. Inspect the ball joint for looseness in the axial

direction while shaking the tie-rod end vertically. If
there is looseness, replace the tie-rod end
assembly.

CAUTION

• Do not remove the nut from ball joint. Loosen

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

• Hang the special tool with cord to prevent it

from falling.

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 fig-
ure.

Replace the self-locking nut with a regular nut, and
then install special tool steering linkage puller
(MB991113) as shown in the figure.

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: 10 N

⋅m or less

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-lock-
ing 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 <4A9>

Tightening torque: 28

± 3 N⋅m <4G1>

CHECK OF STEERING FORCE TO LOCK

M1372001700688

1. Verify that the tyre pressure is within the

specification. Use tyres with more than 80% of the
tread depth remained.

Specified tyre inflation pressure: 220 kPa

2. Place the vehicle on a level surface and turn the

steering wheel to the straight ahead position.

4. Attach a spring scale to the circumference of the

steering wheel and measure the steering force
when the steering wheel is turned to left and right
from the straight ahead position within 90

°. At the

same time, verify that the steering force does not
vary excessively in both directions.

Standard value:

Steering force

4A9

25 N or less

4G1

40 N or less

Fluctuation

4A9

6.0 N or less

4G1

10.0 N or less

5. If not within the specification, inspect and adjust

the steering system components.

STEERING WHEEL RETURN TO CENTRE
CHECK

M1372001800436

Carry out the test run for return check and check the
following.
1. Carry out gentle cornering and hard cornering and

check the steering force and the return do not
have the difference between left and right by the
feeling.

2. Turn the steering wheel at a 90

° angle and keep it

for a few seconds while driving at about 35 km/h
speed and then check that the steering wheel
returns more than 70

° when taking hand off.

TIE ROD END BALL JOINT DUST COVER
CHECK

M1372008600381

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

M1372013500368

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 mecha-
nism has already operated, replace the steering col-
umn 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

If the vehicle continues to be driven after the
collision absorbing mechanism has oper-
ated, the steering column shaft may be dam-
aged while it is in use.
