SteeringGearandLinkage
STEERING GEAR

• Check gearhousing andboots forlooseness, damageor
grease leakage.
• Check connection withsteering columnforlooseness.

STEERING LINKAGE

• Check balljoint, dustcover andother component partsfor
looseness, wear,damage orgrease leakage.

Checking PowerSteering FluidandLines

• Check fluidlevel withengine off.
• Check fluidlevel using dipstick onreservoir cap,orrefer-
ring tothe scale onreservoir tank.Use"HOT" rangeatfluid
temperatures of50 to80°C (122to176°F). Use"COLD"
range atfluid temperatures of
a
to 30°C (32to86°F).

CAUTION:
• Donot overfill.
• Recommended fluidisAutomatic Transmission Fluid

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.

SERVICE
Rear AxleandRear Suspension Parts

Check axleandsuspension partsforexcessive play,wear or
damage.
• Shake eachrearwheel tocheck forexcessive play.
• Retighten allnuts andbolts tothe specified torque.

Tightening torque:
Refer toREAR SUSPENSION (RA-8).

• Check shockabsorber for
oil
leakage orother damage.

Rear Wheel Bearing

• Check axialendplay.

Axial endplay:
0.05 mm(0.0020 in)orless

• Check thatwheel hubbearings operatesmoothly.
• Check tightening torqueofwheel bearing locknut.

(OJ:

• Replace wheelbearing assembly ifthere isaxial endplay
or wheel bearing doesnotturn smoothly. RefertoREAR

CAUTION:
• Before removing therear wheel hubassembly, disconnect
the ABS wheel sensor fromtheassembly. Thenmove it
away fromthehub assembly. Failuretodo somay result in
damage tothe sensor wiresandthesensor becoming inop-
erative.
• Wheel hubbearing doesnotrequire maintenance. Ifany of
the following symptoms arenoted, replace wheelhubbear-
ing assembly.
• Growling noiseisemitted fromwheel hubbearing during
operation.
• Wheel hubbearing dragsorturns roughly. Thisoccurs
when turning hubbyhand afterbearing locknutistightened

CAUTION:
• Before removing therear suspension assembly,disconnect
the ABS wheel sensor fromtheassembly. Failuretodo so
may result indamage tothe sensor wiresandthesensor
becoming inoperative.

• Remove suspension assembly.
1. Disconnect brakehydraulic linesandparking brakecableat
toggle lever.(Models withdrum brakes.)
• Drain brake fluidbefore disconnecting brakelines.
2. Disconnect parkingbrakecablefromcaliper andremove
brake caliper androtor. (Models withdiscbrakes.)

Suspend caliperassembly withwire soasnot tostretch brake
hose.
Be careful nottodepress brakepedal, orpiston willpop out.
Make surebrake hoseisnot twisted.

3. Using atransmission jack,raise torsion beamalittle, and
remove nutsandbolts fromthetrailing arm,shock absorber
assembly (lowerside)andlateral link.
4. Lower transmission jack,andremove suspension.
5. Remove luggagecompartment trim.Refer toBT section.
6. Remove strutsecuring nuts(upper side).Thenpulloutstrut
assembly.
• Install suspension assembly.

CAUTION: Refill withnewbrake fluid"DOT
3".

Never reusedrained brakefluid.

1. Attach torsion beam,attrailing armandlateral link,tovehi-
cle. Donot tighten boltsatthis time.
2. Using atransmission jack,place lateral linkand control rod
horizontally againsttorsionbeam.Tighten laterallinkon
vehicle.
3. Attach shockabsorber assembly tovehicle. Thentighten the
lower sideofshock absorber assembly.
4. Lower torsion beamtofully extended position.Remove
transmission jackandtighten torsion beam,attrailing arm,
to specified torque.RefertoRA-8.
5. Install brakehydraulic linesandtighten flarenuts.
