STEERING WHEEL FREE PLAY CHECK

M1372001000377

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: 50 mm (2.0 inches)

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 (1.1
pound) towards the steering wheel circumference and check
the play.

Standard value (steering wheel play with the engine
stopped): 10 mm (0.4 inch) or less

5. If the play exceeds the standard value, check the steering

gear backlash and ball joint end play (Refer to

P.37A-16

).

STEERING ANGLE CHECK

M1372001100426

1. Place the front wheel on a turning radius gauge and

measure the steering angle.

Standard value:

CAUTION

When the steering wheel is turned to lock, check that the
clearance between the knuckle and the stopper is 1 mm
(0.04 inch) or more.

2. Check that the toe-in is within the standard value. If the

steering angle is outside the standard value, adjust the
toe-in. (Refer to GROUP 33A, On-vehicle Service

P.33A-3

.)

Standard value: 3.5

± 3.5 mm (0.14 ± 0.14 inch)

3. Adjust the steering angle with the stopper bolt.

STEERING GEAR BACKLASH CHECK

M1372001300066

1. Jack up the vehicle front and hold the steering wheel in the

straight ahead position.

2. Take a part the pitman arm and the relay rod. (Refer to

P.37A-30

.)

3. Measure the steering gear backlash at the pitman arm top

end with a dial indicator.

Limit: 0.5 mm (0.02 inch)

4. If the measured value exceeds the limit, screw in the

steering gear box adjusting bolt until the steering wheel free
play is within the standard value.
NOTE: Be sure to make the adjustment with the steering
wheel in the straight ahead position.
NOTE: If the adjusting bolt is overtightened, more steering
effort will be required, and return of the wheel will be
adversely affected.

TIE ROD END BALL JOINT VARIATION CHECK
(SHAFT DIRECTION)

M1372001400074

Required Special Tools:

• MB99948: Linkage Joint Gauge

1. Hold the ball joint with special tool MB990984.
2. Set special tool MB990948 scale at its highest and measure

variation with the ball stud compressed. The variation should
locate between the highest and center scales.

Limit: 1.5 mm (0.06 inch)

3. When the variation exceeds the center scale, replace the tie

rod end.
NOTE: Even if the variation is within the limit, check the ball
joint breakaway torque.

Required Special Tools:

• MB990326: Preload Socket

• MB991897: Ball Joint Remover

CAUTION

• Do not remove the nut from ball joint. Loosen it and use

special tool MB991897 to avoid possible damage to the
ball joint threads.

• Hang special tool MB991897 with cord to prevent it

from falling.

1. Install the special tool MB991897 as shown in the figure.

2. Turn the bolt and knob as necessary to make the jaws of

special tool MB991897 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. Measure the ball joint breakaway torque with
special tool MB990326.

Standard value: 3.0 N

⋅m (27 in-lb)

5. If the breakaway torque exceeds the standard value, replace

the tie rod end.

6. If the breakaway torque is under the standard value, check

the ball joint for end play or ratcheting. If no end play or
ratcheting, the ball joint can be re-used.

7. Tighten the nut to the specified torque and install a new

cotter pin.

Tightening torque: 44

− 54 N⋅m (32 − 40 ft-lb)

STATIONARY STEERING EFFORT CHECK

M1372001700387

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 check the engine idle speed.

Standard value:700

± 100 r/min

3. Attach a spring scale 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 (8.81 lb) or less
Fluctuation allowance: 5 N (1.12 lb) or less

4. If the measured value did not conform to the standard value,

refer to POWER STEERING DIAGNOSIS

P.37A-4

to check

and adjust the steering force.
