WHEEL HUB
Revision: 2007 April2007 M35/M45
5. Separate the wheel hub and bearing assembly from drive shaft
by lightly tapping the end with a hammer (suitable tool) and
wood block, and then remove hub lock nut.
CAUTION:

Do not place drive shaft joint at an extreme angle. Also be
careful not to overextend slide joint.

Do not allow drive shaft to hang down without support for
housing (or joint sub-assembly), shaft and other parts.
NOTE:
Use a puller (suitable tool), if the wheel hub and bearing assem-
bly and drive shaft cannot be separated even after performing
the above procedure.
6. Remove the wheel hub and bearing assembly mounting bolts.
7. Remove the wheel hub and bearing assembly.
Axle Housing
1. Refer to the procedure from 1 to 5 in “Wheel Hub and Bearing Assembly”. RAX-5, "REMOVAL" .
2. Remove parking brake shoe and parking brake cable from back plate. Refer to PB-6, "
PARKING BRAKE
SHOE" , Refer to PB-4, "PARKING BRAKE CONTROL" .
3. Remove coil spring. Refer to RSU-16, "
REAR LOWER LINK & COIL SPRING" .
4. Remove mounting bolt and nut in axle side of shock absorber with a power tool.
5. Remove axle side nuts and bolts on radius rod and front lower link with a power tool. Refer to RSU-14,
"RADIUS ROD" , RSU-15, "FRONT LOWER LINK" .
6. Remove cotter pin, then loosen suspension arm mounting nut of axle housing.
7. Remove suspension arm from axle housing so as not to damage ball joint boot using ball joint remover
(suitable tool), and then remove axle housing from the vehicle.
CAUTION:

Temporarily tighten nuts to prevent damage to threads and to prevent ball joint remover (suit-
able tool) from coming off.

Do not place drive shaft joint at an extreme angle. Also be careful not to overextend slide joint.

Do not allow drive shaft to hang down without support for counterpart such as joint sub-assem-
bly, and other parts.
8. Remove the wheel hub and bearing assembly from axle housing.
9. Remove anchor block mounting nuts, and then remove anchor block and back plate from axle housing.
INSPECTION AFTER REMOVAL
Wheel Hub and Bearing Assembly
Check the wheel hub and bearing assembly for wear, cracks, and damage. Replace if there are.
Axle Housing
Check axle housing for wear, cracks, and damage. Replace if there are.
Ball Joint Inspection
Check for boot breakage, axial looseness, and torque of suspension arm ball joint. Refer to RSU-12, "SUS-
PENSION ARM" .
INSTALLATION
Wheel Hub and Bearing Assembly

Installation is the reverse order of removal. For tightening torque refer to RAX-5, "COMPONENT" .
CAUTION:
Do not reuse non-reusable parts.

PRECAUTIONS
Revision: 2007 April2007 M35/M45
PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NIS0023J
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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:

To 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.

Improper 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.

Do 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.
Precautions NIS0023K

Disconnect both battery cables in advance.

Disconnect air bag system line in advance.

Do not tamper with or force air bag lid open, as this may adversely affect air bag performance.

Be careful not to scratch pad and other parts.

When removing or disassembling any part, be careful not to damage or deform it. Protect parts, which
may get in the way with cloth.

When removing parts with a screwdriver or other tool, protect parts by wrapping them with vinyl or tape.

Keep removed parts protected with cloth.

If a clip is deformed or damaged, replace it.

If an unreusable part is removed, replace it with a new one.

Tighten bolts and nuts firmly to the specified torque.

After re-assembly has been completed, make sure each part functions correctly.

Remove 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.
Then wipe the area with a soft dry cloth.

Do not use any organic solvent, such as thinner or benzine.
