SERVICE ADJUSTMENT PROCEDURES
REAR WHEEL ALIGNMENT INSPECTIONN17FAAC
The rear suspension assembly must be free of worn, loosen or
damaged parts prior to measurement of rear wheel alignment.
Standard value:
Toe-in (Left-right difference)
Of3 mm (Of.118 in.)
Camber-45’ + 30’
NOTEThe rear wheel alignment is set at the factory and cannot be
adjusted.If toe-in or camber is not within the standard value, replace
bent or damaged parts.
WHEEL BEARING END PLAY ADJUSTMENT,7FBA0
1.Inspect the play of the bearings while the vehicle is jacked
up and resting on floor jack.
2.Remove the hub cap and then release the parking brake.
3. Remove the caliper assembly and the brake disc.
4. Check the bearing’s end play.
Place a dial gauge against the hub surface; then move the
hub in the axial direction and check whether or not there isend play.
Limit: 0.01 mm
(.004 in.) or less
NOTE12AO531If the limit value is exceeded, the lock nut should be
tightened to the specified torque and check the end play
again.
5.Replace the rear hub bearing unit if an adjustment cannot
be made to within the limit.

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.

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.
