PRECAUTIONSANDPREPARATION
SBR820B Precautions
• When installing eachrubber part,finaltightening mustbe
carried outunder unladen condition* withtires onground.

*:
Fuel, radiator coolantandengine oilfull. Spare tire,jack,
hand tools andmats indesignated positions.
• Use flare nutwrench whenremoving orinstalling brake
tubes.
• After installing removedsuspension parts,check wheel
alignment.
• Donot jack upatthe trailing armandlateral link.
• Always torquebrakelineswhen installing.

PRELIMINARY INSPECTION

Make following checks.Adjust,repairorreplace ifnecessary.
• Check tiresforwear andforimproper inflation.
• Check rearwheel bearings forexcessive play.
• Check wheelrunout.

Wheel runout: RefertoSOS inFA section.

• Check thatrear shock absorber worksproperly.
• Check rearaxleandrear suspension partsforexcessive

CAMBER
Camber ispreset atfactory andcannot beadjusted.
Camber: Refer toSOS (RA-12).

• Ifthe camber isnot within specification, inspectandreplace
any damaged orworn rearsuspension parts.

TOE-IN
Toe-in ispreset atfactory andcannot beadjusted.
Measure toe-inusingfollowing procedure. Ifout of
specification, inspectandreplace anydamaged orworn rear
suspension parts.
WARNING:
• Perform following procedure alwaysonaflat surface.
• Make surethatnoperson isin front ofthe vehicle before
pushing it.

1. Bounce rearofvehicle upand down tostabilize theposture.
2. Push thevehicle straight aheadabout5m (16
ft).

3. Putamark onbase lineofthe tread (rearside) ofboth tires at
the same height ofhub center. Thismark isameasuring point.
4. Measure distance"A"(rear side).
5. Push thevehicle slowlyaheadtorotate thewheels 180
degrees (1/2turn).

If the wheels haverotated morethan180degrees (1/2turn), try
the above procedure againfromthebeginning. Neverpush
vehicle backward.

6. Measure distance"B"(front side).

Total toe-in:
Refer toSOS, RA-12.

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::

mm
(::l::

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.

6. Move rackover itsentire stroke several times.
7. Measure pinionrotating torquewithintherange of180° from
neutral position.
Stop thegear atthe point ofmaximum torque.
8. Loosen adjusting screw,thenretighten itto 4.9 N'm (50

to knuckle arm.
b. Connect allpiping andfillwith steering fluid.
c. Start engine andbleed aircompletely.
d. Disconnect steeringcolumnlowerjointfrom thegear.
e. Keep engine atidle and make suresteering fluidhas
