SERVICE ADJUSTMENT PROCEDURiS
< MANUAL STEERING >
STEERING WHEEL FREE PLAY CHECKNOSFAAE
1. Set front wheels straight ahead.
2.’ Measure the play on steering wheel circumference before
wheels move when slightly moving steering wheel in both
directions.Limit: 30 mm (1.2
in.1
3.When the play exceeds the limit, check play in steering shaft
connection and steering linkage. Correct or replace.4. When
(3) check provides good results, check the following
to adjust:l Remove the steering gear box, check and adjust total
pinion starting torque.
STEERING ANGLE CHECKNlSFDBFl1. Set front wheels on turning radius gauge and measure
steering angle.
Standard values:
Inner wheel37000’
2 20
Outer wheel30000’
2. When not within the standard value, it is probably a toe
problem. Adjust toe (refer to GROUP 2-Service Adjusttierit
Procedures) and recheck.
TIE ROD END BALL JOINT VARIATION CHECK
(SHAFT DIRECTION)NlSFPAB1. Hold the ball joint with pliers.
2. Set a caliper gauge as illustrated and measure the dis-
placement with the ball stud compressed.
Limit: 1.5 mm
LO59 in.)
3.If the measured displacement exceeds the limit, replace the
tie-rod end.
CautionEven if the variation is within the limit, check ball joint
starting torque.

Nl9FEBCa1. Disconnect tie rod and knuckle with special tool.
Caution
Be sure to tie the cord of the special tool to the nearby
part-2. Move ball joint stud several times and install nut on stud.
’ Measure ball joint starting torque.
Standard value:
0.5-2.5 Nm (4-22 in.lbs.1
3.When starting torque exceeds the standard value, replace tie
rod end.
4.When the starting torque is under the standard value, checkfor play or ratcheting in ball joint. If none of these, it is still
serviceable.
STEERING WHEEL CENTERINGNlSFNAC
SIMPLIFIED STEERING WHEEL CENTERING
Determining Steering Wheel’s Off Center1. For the road test, take along chalk or tape and a ruler.
2. Drive straight ahead on an uncambered level surface.
3.When the vehicle’s wheels are pointing straight ahead, markthe steering wheel hub and column cover with a chalk or
tape line.4. Stop the vehicle and line up the marks on the hub and
column cover.5. Place a tape strip or mark on the steering wheel rim.
6.Hold a ruler next to the rim as shown in the illustration, and
then steer the steering wheel until it is in the desired centered
position.
7.Record the distance the strip or mark on the rim has moved.This is how far the steering wheel is off center. If it is more
than 16 mm
(518 in.) off center, it can be centered by
indexing it ten degrees towards the center.
,Indexing Steering Wheel to Center
ltThe steering wheel shaft has 36 splines, allowing the steering
wheel to be indexed in tendegree increments.
1. Remove the steering wheel.
2. Without disturbing the position of the steering wheel shaft,
re-install the wheel as near on-center as possible.

Turn both tie rods in the same direction.
PRECISIG~ STEERING WHEEL CENTFFJIhll
In general,. the tie rods are adjusted to steer the’front wheels inthe same direction that the steering wheel is off center. If the
steering wheel is off canter to the left, center it by adjusting the
tie rods to make the front wheels steer toward the left, and vice
versa.1. Mark the tie rods and tie rod ends with chalk before
loosening the lock nuts.
2. Hold the tie rod with a wrench and loosen the lock nut.
3.Hold the tie rod end with a wrench and turn the tie rod the
desired number of turns.

4. Tighten the lock nut to specified torque, taking care not to
turn the tie rod.

SERVICE ADJUSTMENT PROCEDURES
STEERING WHEEL FREE PLAY CHECKNlSFABH
1. With engine running (hydraulic operation), set front wheels
straight ahead.2. Measure the play on steering wheel circumference before
wheels start to move when slightly moving steering wheel
in both directions.
Limit: 30 mm (1.2
in.13. When the play exceeds the limit, check for play on steering
shaft connection and steering linkage. Correct or replace.
4.If the free play still exceeds the limit value set steering wheel
straight ahead with engine stopped. Load 5
N (1 lb.1 towardssteering wheel circumference and check play.
Standard value (steering wheel play with engine
stopped): 11 mm
I.43 in.)
If the play exceeds the standard value, remove steering gearbox and check total pinion torque.
