Checking
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
''DEXRON™,, typeorequivalent.

•Check linesforimproper attachment, leaks,cracks,
damage, looseconnections, chafinganddeterioration.
• Check rackboots foraccumulation ofpower steering 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:
186 •255 N.m (19-26 kg-m, 137•188 ft-Ib)

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

REMOVAL
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
to specified torque.
