ON-VEHICLE SERVICE

STEERING WHEEL FREE PLAY CHECK

With the engine running (hydraulic pressure operating),
put the front wheels in straight-ahead position.

Lightly turn the steering wheel left and right to measure
circumferential play on the steering wheel before the
wheels start to move.

Limit: 30 mm or less

When the play exceeds the limit, check steering shaft
connections and steering linkage for looseness. Repair
or replace if necessary.

If the play still exceeds the limit, put the steering wheel
in straight-ahead position with the engine stopped. Then,
load 5 N in the circumferential direction on the steering
wheel and measure circumferential play.

Standard value: 0 – 10 mm

In case the play exceeds the standard value again, remove
the steering gear box and linkage. Then, check and adjust
total pinion torque. (Refer to P.37A-18.)

STEERING ANGLE CHECK

Put the front wheels on a turning radius gauge and measure
steering angle.

Standard value:

Inner wheels

40’

Outer wheels <For reference>

10’

If the standard values are not met, toe-in is probably
incorrect. Adjust the toe-in, seeing GROUP 33A –
On-vehicle Service, and recheck the steering angle.

TIE ROD END BALL JOINT STARTING TORQUE
CHECK

Use the special tool to disconnect the tie rod and knuckle.

Caution
(1) In order not to damage the ball joint thread, the

tie rod end mounting nut must be only loosened
but not removed from the ball joint. Also, be sure
to use the special tool.

(2) Tie the special tool with a cord so as not to fall

off.

After swinging the ball joint stud several times, install the
nut on the stud. Then, measure ball joint turning torque
with the special tool.

Standard value: 0.5 – 2.5 Nm

When the torque is over the standard value, replace the
tie rod end.

When the torque is below the standard value, check the
ball joint for looseness or ratcheting. If none of these found,
the ball joint is still serviceable.

STATIONARY STEERING EFFORT CHECK

With the vehicle stopped on a flat, paved surface, put
the steering wheel in straight–ahead position.

Start the engine and keep it at 1,000

100 r/min.

Attach a spring balance to the steering wheel outer bar.
Measure steering effort required to turn the steering wheel
from the straight-ahead position to the left and right (within
a range of 1.5 turns). Also see that no significant fluctuation
is present in the steering effort.

Standard value:

Steering effort

27 N or less <Limit: 30 N or less>

Fluctuation

5.9 N or less

If the standard values are not met, check and adjust the
related parts.

STEERING WHEEL RETURNABILITY CHECK

Check returnability as follows on 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.

At a speed of about 35 km/h, turn the steering wheel
90

, keep it there for 1 to 2 seconds and release. When

the steering wheel returns more than 70

, it has a good

returnability.

NOTE
You may have momentary increase in effort when turning
the steering wheel quickly, which is normal. This happens
due to insufficient job of the oil pump when the engine
is running at low speed such as idling.

OIL PUMP BELT TENSION CHECK

Refer to GROUP 11A – On-vehicle Service.
