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

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.

erative.
• Wheel hubbearing doesnotrequire maintenance. Ifany of
the following symptoms arenoted, replace wheelhubbear-
ing assembly.
• Growling noiseisemitted fromwheel hubbearing during

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

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

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.
