INSPECTION AFTER REMOVAL
Axle Shaft Bearing and Cup
lCheck that the axle shaft bearing and cup roll freely and are free from noise, cracks, pitting and wear.
Replace if necessary.
Axle Shaft Retainer
lCheck for deformation and cracks. Replace if necessary.
Rear Axle Case
lCheck the exterior and inner machined surfaces for deformation and cracks. Replace if necessary.
INSTALLATION
Installation is in the reverse order of removal.
When installing pay attention to following points:
lInstall a new shaft guide and a new oil seal into the rear axle case.
CAUTION:
lDo not reuse the axle oil seal. The axle oil seal must be replaced every time the axle shaft assem-
bly is removed from the axle shaft housing.
lWhen installing oil seals, apply multi-purpsose grease to oil seal lips.
lInstall four new lock nuts to secure the axle shaft assembly to the rear axle case, and tighten lock nuts to
the specified torque. Refer toRAX-7, "
Removal and Installation".
lReinstall the rear brake drum. Refer toBR-31, "Removal and Installation of Drum Brake Assembly".
lAdjust the differential gear oil level.
Refer toRFD-9, "
DIFFERENTIAL GEAR OIL", for M226 without LD.
Refer toRFD-9, "
DIFFERENTIAL GEAR OIL", for M226 with LD.
lReinstall the wheel. Refer toWT-5, "Rotation".
DISASSEMBLY
1. Remove the ABS sensor rotor. Refer toBRC-39, "SENSOR ROTOR".
2. Remove the snap ring from the axle shaft using a suitable snap ring pliers.
3. Secure the axle shaft in a suitable vise as shown, and use a
brass hammer to remove studs (4) from the axle shaft retainer.
CAUTION:
lMount the axle shaft using a soft jaw vise to avoid dam-
aging the axle shaft retainer.

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EIS00CE9
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:
lTo avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.
lImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
lDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
PrecautionsEIS00B92
lDisconnect both battery cables in advance.
lNever tamper with or force air bag lid open, as this may adversely affect air bag performance.
lBe careful not to scratch pad and other parts.
lWhen removing or disassembling any part, be careful not to damage or deform it. Protect parts which may
get in the way with cloth.
lWhen removing parts with a screwdriver or other tool, protect parts by wrapping them with vinyl or tape.
lKeep removed parts protected with cloth.
lIf a clip is deformed or damaged, replace it.
lIf an unreusable part is removed, replace it with a new one.
lTighten bolts and nuts firmly to the specified torque.
lAfter re-assembly has been completed, make sure each part functions correctly.
lRemove stains in the following way.
Water-soluble stains:
Dip a soft cloth in warm water, and then squeeze it tightly. After wiping the stain, wipe with a soft dry cloth.
Oil stain:
Dissolve a synthetic detergent in warm water (density of 2 to 3% or less), dip the cloth, then clean off the stain
with the cloth. Next, dip the cloth in fresh water and squeeze it tightly. Then clean off the detergent completely.
Thenwipetheareawithasoftdrycloth.
lDo not use any organic solvent, such as thinner or benzine.

lInspection is required when detecting any noise or malfunction while driving or turning. Improper condition
of oil or differential case assembly is suspected. Refer toRFD-3, "
METHOD FOR TROUBLESHOOTING"
.
METHOD FOR TROUBLESHOOTING
1. Check differential gear oil level and differential gear oil leakage. Refer toRFD-9, "Checking Differential
Gear Oil".
2. Changing differential gear oil. Refer toRFD-9, "
Changing Differential Gear Oil".
3. Start engine. Drive for 10 min.
4. Again changing differential gear oil. Refer toRFD-9, "
Changing Differential Gear Oil".
5. Start engine. Drive for 10 min. Check if any noise or improper oil condition is detected.
lIf OK, check differential gear oil level and differential gear oil leakage. Refer toRFD-9, "Checking Differ-
ential Gear Oil".
lIf NG, replace differential case assembly after checking each part of final drive. Refer toRFD-15, "Dis-
assembly and Assembly".
Service Notice or PrecautionsEDS0038Z
lCheck for the correct installation status prior to removal or disassembly. If matching marks are required,
be certain they do not interfere with the function of the parts when applied.
lOverhaul should be done in a clean work area, it is preferable to work in dust proof area.
lBefore disassembly completely remove sand and mud from the exterior of the unit, preventing them from
entering into the unit during disassembly or assembly.
lCheck appearance of the disassembled parts for damage, deformation, and unusual wear. Replace them
with new ones if necessary.
lGaskets, seals and O-rings should be replaced any time the unit is disassembled.
lIn principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, observe it.
lClean and flush the parts sufficiently and blow-dry them.
lBe careful not to damage sliding surfaces and mating surfaces.
lWhen applying sealant, remove the old sealant from the mounting surface; then remove any moisture, oil,
and foreign materials from the application and mounting surfaces.
lAlways use shop paper for cleaning the inside of components.
lAvoid using cotton gloves or shop rags to prevent entering of lint.
lDuring assembly, observe the specified tightening torque, and apply new differential gear oil, petroleum
jelly, or multi-purpose grease as specified.
