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.

PRECAUTION
Supplemental RestraintSystem(SRS)"AIR
BAG" (DualAirBag System)

The Supplemental RestraintSystem"AirBag", usedalong withaseat belt, helps toreduce therisk or
severity ofinjury tothe driver andfront passenger inafrontal collision. TheSupplemental Restraint
System consists ofair bag modules (locatedinthe center ofthe steering wheelandonthe instrument
panel onthe passenger side),adiagnosis sensorunit,warning lamp,wiring harness andspiral cable.

WARNING:
• Toavoid rendering theSRS inoperative, whichcouldincrease therisk ofpersonal injuryordeath
in the event ofacollision whichwould resultinair bag inflation, allmaintenance mustbeperformed
by an authorized NISSANdealer.
• Improper maintenance, includingincorrectremovalandinstallation ofthe SRS, canlead topersonal
injury caused byunintentional activationofthe system.
• Donot use electrical testequipment onany circuit related tothe SRS unless instructed tointhis
Service Manual. SRSwiring harnesses arecovered withyellow insulation eitherjustbefore the
harness connectors orfor the complete harness,foreasy identification.
