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

Service 

− Front Wheel Alignment Check and 

Adjustment

2. Place the front wheel on a turning radius gauge 

and measure the steering angle.

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.

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.

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 Nm <4A9>

Tightening torque: 28 

± 3 Nm <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:

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.
