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.

1. Remove brakecaliper assembly.
2. Remove wheelbearing locknut.
3. Remove brakerotor(models withdiscbrake) orbrake drum
(models withdrum brakes).
4. Remove wheelhubbearing fromspindle.

Brake hosedoes notneed tobe disconnected frombrake cali-
per.
Suspend caliperassembly withwire soas not tostretch brake

• Install wheel hubbearing.
• Tighten wheelbearing locknut.
Before tightening, applyoiltothreaded portionofrear spin-
dle and both sides ofplain washer.

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.

remove nutsandbolts fromthetrailing arm,shock absorber
assembly (lowerside)andlateral link.
4. Lower transmission jack,andremove suspension.
5. Remove luggagecompartment trim.Refer toBT section.

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.

Precautions forSRS "AirBag" and"Seat Belt
Pre-tensioner" Service

• Donot use acircuit testertocheck SRScircuits.
• Before servicing theSRS. turnignition switch"OFF", disconnect bothbattery cablesandwait forat
least 10minutes.
For approximately 10minutes afterthecables areremoved, itis still possible forthe airbag to
deploy. Therefore, donot work onany SRS connectors orwires untilatleast 10minutes havepassed.
• For single airbag system, donot separate diagnosis sensorunitfrom steering wheel.
• For dual airbag system. diagnosis sensorunitmust always beinstalled withtheir arrow marks
"Q"

pointing towards thefront ofthe vehicle forproper operation. Alsocheck diagnosis sensorunitfor
cracks. deformities orrust before installation andreplace asrequired.
• The spiral cablemustbealigned withtheneutral position sinceitsrotations arelimited. Donot
attempt toturn steering wheelorcolumn afterremoval ofsteering gear.
• Handle airbag module carefully. Alwaysplaceitwith thepad side facing upward.
• Donot use oldbolts afterremoving anySRS parts; replace withnewones. Conduct self-diagnosis
to check entire SRSforproper function.
• For dual airbag system, instrument panelassembly shouldbereplaced afterairbag inflates.

Maintenance
Items

1. Check "AIRBAG" warning lampoperation
After turning ignition keyto"ON" position, "AIRBAG"
warning lampilluminates. The"AIR BAG" warning lamp
will turn offafter about 7seconds ifno malfunction is
detected. If any ofthe following airbag warning lampconditions
occur, immediately checktheairbag system. RefertoRS-32
and 43for details.
The warning lampdoesnotilluminate whentheignition
switch isturned "ON".
The warning lampdoesnotturn offabout 7seconds after
the ignition switchisturned "ON".
The warning lampturns offabout 7seconds aftertheigni-
