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

play.
• Check vehicle posture (Unladen*).
*: Fuel, radiator andengine oilfull. Spare tire,jack, hand
tools andmats indesignated positions.

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).

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

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.

Pre-checking

• Make surethatwheel alignment iscorrect.

Wheel alignment:
Refer toSOS inFA section.

• Verify thatthesteering geariscentered beforeremoving
the steering wheel.

Checking

1.Check thatthesteering wheelisin the neutral position when
driving straight ahead.
2. Ifit is not inthe neutral position, removethesteering wheel
and reinstall itcorrectly.
3. Ifthe neutral position isbetween twoteeth,. loosen tie-rod
lock nuts. Turnthetie-rods bythe same amount inopposite
directions onboth leftand right sides.

Front Wheel Turning Angle •

1. Rotate steering wheelallthe way right andleft;measure
turning angle.

Turning angleoffull turns:
Refer toSOS inFA section.

2. Ifit is not within specification, checkrackstroke.

Refer toSOS (ST-35).
SMA127 Checking GearHousing Movement

1. Check themovement ofsteering gearhousing duringsta-
tionary steering onadry paved surface.
• Apply aforce of49 N(5 kg, 11Ib) tosteering wheeltocheck
the gear housing movement.
Turn offignition keywhile checking.

Movement ofgear housing:
