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.

;EEE;D END 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.
