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

Ii
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.

•
Before proceeding withdisassembly, thor-
oughly cleantheoutside ofthe transaxle. Itis
important toprevent theinternal partsfrom
becoming contaminated bydirt orother for-
eign matter.
• Disassembly shouldbedone inaclean work
area.
• Use lint-free clothortowels forwiping parts
clean. Common shopragscanleave fibers
that could interfere withtheoperation ofthe
transaxle.
• Place disassembled partsinorder, onaparts
rack, foreasier andproper assembly.
• Allparts should becarefully cleaned-witha
general purpose, non-flammable solvent
before inspection orreassembly.
• Gaskets, sealsandO-rings shouldbe
replaced anytime thetransaxle isdisassem-
bled.
• Itis very important toperform functional tests
whenever theyareindicated. •
The valve bodycontains precision partsand
requires extremecarewhen partsare
removed andserviced. Placedisassembled
valve bodyparts inorder, onaparts rack,for
easier andproper assembly. Carewillalso
prevent springs andsmall partsfrombecom-
ing scattered orlost.
• Properly installedvales,sleeves, plugs,etc.
will slide along theirbores inthe valve body
under theirownweight.
• Before assembly, applyacoat ofrecom-
mended ATFtoall parts. Apply petroleum
jelly toprotect O-ringandseals, orhold bear-
ings andwashers inplace during assembly.
Do not use grease.
• Extremely careshould betaken toavoid dam-
age toO-rings, sealsandgaskets when
assembling.
• After overhaul, refillthetransaxle withnew
ATF.

Before checking frontwheel alignment, besure tomake apre-
liminary inspection (Unladen*).
*: Fuel, radiator coolantandengine oilfull. Spare tire,jack,
hand tools andmats indesignated positions.

SFA575B PRELIMINARY INSPECTION

1. Check tiresforwear andimproper inflation.
2. Check wheelrunout.

Wheel runout:
Refer toSOS (FA-30).

3. Check frontwheel bearings forlooseness.
4. Check frontsuspension forlooseness.
5. Check steering linkageforlooseness.
6. Check thatstruts workproperly.
7. Check vehicle posture (Unladen).

TOE-IN Measure toe-inusingfollowing procedure.
WARNING:
• Perform following procedure alwaysonaflat surface.
• Make surethatnoperson isin front ofthe vehicle before
pushing it.

1. Bounce frontofvehicle upand down tostabilize theposture.
2. Push thevehicle straight aheadabout5m (16 ft).
3. Put amark onbase lineoftread (rearside) ofboth tires at
the same height ashub center. Thesearemeasuring points.
4. Measure distance"A"(rear side).
5. Push thevehicle slowlyaheadtorotate thewheels 180
degrees (1/2turn).

If the wheels haverotated morethan180degrees
(112
turn), try
the above procedure againfromthebeginning. Neverpush

1. Measure camber,casterandkingpin inclination ofboth right
and leftwheels withasuitable alignment gauge.

Camber, CasterandKingpin inclination:
Refer toSOS (FA-29).

2. Ifcamber, casterorkingpin inclination isnot within
specification, inspectfrontsuspension parts.Replace dam-
