Pre-checking
• Make surethatwheel alignment iscorrect.
Wheel alignment:
Refer toSOS inFA section.
• Verify thatthesteering geariscentered beforeremoving
the steering wheel.
Checking
SST490BA
1.Check thatthesteering wheelisin the neutral position when
driving straight ahead.
2. Ifit is not inthe neutral position, removethesteering wheel
and reinstall itcorrectly.
3. Ifthe neutral position isbetween twoteeth,. loosen tie-rod
lock nuts. Turnthetie-rods bythe same amount inopposite
directions onboth leftand right sides.
Front Wheel Turning Angle •
1. Rotate steering wheelallthe way right andleft;measure
turning angle.
Turning angleoffull turns:
Refer toSOS inFA section.
2. Ifit is not within specification, checkrackstroke.
Rack stroke
"S":
Refer toSOS (ST-35).
SMA127 Checking GearHousing Movement
1. Check themovement ofsteering gearhousing duringsta-
tionary steering onadry paved surface.
• Apply aforce of49 N(5 kg, 11Ib) tosteering wheeltocheck
the gear housing movement.
Turn offignition keywhile checking.
Movement ofgear housing:
:I:
2 mm
(:I:
0.08 in)orless
2. Ifmovement exceedsthelimit, replace mountinsulator after
confirming properinstallation ofgear housing clamps.

SST681B Checking
Fluidlevel
Check fluidlevel using dipstick onreservoir cap,orreferring to
the scale onreservoir tank.
Use "HOT" rangeforfluid temperatures of50 to80°C (122to
176°F).
Use "COLD" rangeforfluid temperatures of0to 30°C (32to
86°F).
CAUTION:
• Donot overfill.
• Recommended fluidisAutomatic Transmission Fluid
''DEXRON™,, typeorequivalent.
Checking Fluidleakage
Check thelines forimproper attachment andforleaks, cracks,
damage, looseconnections, chafingordeterioration.
1. Run engine between idlespeed and1,000 rpm.
Make suretemperature offluid inoil tank rises to60 to80°C
(140 to176°F).
2. Turn steering wheelright-to-Ieft severaltimes.
3. Hold steering wheelateach "lock" position forfive seconds
and carefully checkforfluid leakage.
CAUTION:
Do not hold thesteering wheelinalocked position formore
than 15seconds.
4. Iffluid leakage atconnectors isnoticed, loosenflarenutand
then retighten.
Do not overtighten connectorasthis candamage O-ring,
washer andconnector.
5. Check rackboots foraccumulation ofpower steering fluid.

Bleeding Hydraulic System
1. Raise frontendofvehicle untilwheels areclear ofthe
ground.
2. Add fluid intooiltank tospecified level.Thenquickly turn
steering wheelfullytoright andleftand lightly touchsteer-
ing stoppers.
Repeat steering wheeloperation untilfluid level nolonger
decreases.
3. Start engine.
Repeat step2.above.
• Incomplete airbleeding willcause thefollowing tooccur.
When thishappens, bleedairagain.
a. Air bubbles inreservoir tank
b. Clicking noiseinoil pump
c. Excessive buzzinginoil pump
Fluid noise mayoccur inthe valve oroil pump. Thisiscommon
when thevehicle isstationary orwhile turning thesteering
wheel slowly. Thisdoes notaffect theperformance ordurabil-
ity ofthe system.
Checking SteeringWheelTurning Force(For
power steering)
1. Park vehicle onalevel, drysurface andsetparking brake.
2. Start engine.
3. Bring power steering fluiduptoadequate operating temper-
ature. [Make suretemperature offluid isapproximately 60
to 80°C (140to176°F).]
Tires needtobe inflated tonormal pressure.
4. Check steering wheelturning forcewhen steering wheel
has been turned 360°from theneutral position.
Steering wheelturning force: •
39 N(4 kg, 9Ib) orless
5.
If
steering wheelturning forceisout ofspecification, check
rack sliding force.
a. Disconnect steeringcolumnlowerjointandknuckle arms
from thegear.
b. Start andrunengine atidle tomake suresteering fluidhas
reached normaloperating temperature.
c. Pull tie-rod slowlytomove itfrom neutral position to
::l::
11.5
mm
(::l::
0.453 in)atspeed of3.5 mm (0.138 in)/s.Check that
rack sliding forceiswithin specification.
Average racksliding force:
152.0 -240.3 N(15.5 -24.5 kg,34.2 -54.0 Ib)
Maximum forcedeviation:
98 N(10 kg, 22Ib)
6.
If
rack sliding forceisnot within specification, overhaul
steering gearassembly.
7. Ifrack sliding forceisOK, inspect steering column.Referto

Checking Hydraulic System
Before starting, checkbelttension, drivingpulleyandtirepres-
sure. 1. Set Tool. Open shut-off valve.Thenbleed air.(See "Bleed-
ing Hydraulic System"ST-7.)
2. Run engine.
Make suretemperature offluid intank rises to60 to80°C (140
to 176°F).
WARNING:
Warm upengine withshut-off valvefullyopened. Ifengine is
started withshut-off valveclosed, fluidpressure inoil pump
increases tomaximum. Thiswillraise oiltemperature abnor-
mally.
3. Check pressure withsteering wheelfullyturned toleft and
right positions withengine idlingat1,000 rpm.
CAUTION:
Do not hold thesteering wheelinalocked position formore
than 15seconds.
Oil pump maximum standardpressure:
7,649 -8,238 kPa(76.5 .82.4 bar,
78 -84 kg/cm
2,
1,109-1,194 psi)
4.
If
oil pressure isbelow thestandard pressure, slowlyclose
shut-off valveandcheck pressure.
• When pressure reachesstandard pressure, gearisdam-
aged.
• When pressure remainsbelowstandard pressure, pumpis
damaged.
CAUTION: Do not close shut-off valveformore than15seconds.
5.
If
oil pressure ishigher thanstandard pressure, checkoil
pump flowcontrol valve.
6. After checking hydraulic system,removeToolandaddfluid
as necessary. Thencompletely bleedairout ofsystem.
