age tothe sensor wiresandthesensor becoming inoperative.
1. Remove wheelbearing locknut.
2. Remove brakecaliper assembly androtor.

SWITCH POSITIONS

Switches areshown inwiring diagrams asifthe vehicle isin
the "normal" condition.
A vehicle isin the "normal" conditionwhen:
• ignition switchis"OFF",
• doors, hoodandtrunk lid/back doorareclosed,
• pedals arenotdepressed, and
• parking brakeisreleased.

5GI860DETECTABLE LINESANDNON-DETECTABLE LINES

In some wiring diagrams, twokinds oflines, representing
wires, withdifferent weightareused.
• Aline with regular weight(widerline)represents a"detect-
able lineforDTC (Diagnostic TroubleCode)".A"detectable
line forDTC" isacircuit inwhich ECM(ECCS control mod-
ule) candetect itsmalfunctions withtheon-board diagnos-
tic system.
• Aline with lessweight (thinner line)represents a"non-de-
tectable lineforDTC", A"non-detectable lineforDTC" isa
circuit inwhich ECMcannot detectitsmalfunctions withthe
on-board diagnostic system.

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

Removal andInstallation
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.
