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.

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.

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.
STEERING ANGLE CHECKN19FDBJ1. Set front wheels on turning radius gauge and measure
steering angle.Standard values:
Turbo
Inner wheel
31”30’+2”Outer wheel
27”OOOther models
Inner wheel
35”00’_+2”Outer wheel
2990’
2. When not within the standard value, it is probably a toe
problem. Adjust toe (refer to GROUP 2-Service Adjustment
Procedures) and recheck.TIE ROD END BALL JOINT VARIATION CHECK
(SHAFT DIRECTION)N19FVA8The inspection procedure for the tie rod end ball joint variation
is the same as for the manual steering system. (Refer to
P. 19-7.)
TIE ROD END BALL JOINT STARTING TORQUE

OIL PUMP PRESSURE TESTNl9FlAF
CHECKING THE OIL PUMP RELIEF PRESSURE1. Disconnect the pressure hose from the oil pump, and then
connect the special tools.
2.Bleed the air, and then turn the steering wheel several timeswhile the vehicle is not moving so that the temperature of
the fluid rises to approximately
50-60°C (122-14OOF).3. Start the engine and idle it at 1,000
f 100 rpm.
4. Fully close the shut-off valve of the pressure gauge and
measure the oil pump relief pressure to confirm that it is
within the standard value range.
Standard value: 7.5-8.2
MPa (1,067-1,166 psi)
Caution
Pressure gauge shut off valve must not remain closed formore than 10 seconds.
5.If it is not within the standard value, overhaul the oil pump.
6.Remove the special tools, and then tighten the pressure hoseto the specified torque.
7. Bleed the system.
CHECKING THE PRESSURE UNDER NO-LOAD CONDITIONS1. Disconnect the pressure hose from the oil pump, and then
connect the special tool.
2.Bleed the air, and then turn the steering wheel several timeswhile the vehicle is not moving so that the temperature of
the fluid rises to approximately
50-60°C (122-14OOF).3. Start the engine and idle it at 1,000
-t 100 rpm.
4.
Check whether or not the hydraulic pressure is the standard
value when no-load conditions are created by fully openingthe shut-off valve of the pressure gauge.
Standard value:
0.8-I .O MPa (114-142 psi)
Limit: 1.5
MPa (213 psi)
5. If it is not within the standard value, the probable cause is
a malfunction of the oil line or steering gear box, so check
these parts and repair as necessary.
6.Remove the special tools, and then tighten the pressure hoseto the specified torque.
7. Bleed the system.
