Installation is in the reverse order of removal.

Confirm mating marks are aligned with hose and clamp, then
correct if needed.

To install eye joint, align projection of eye joint with notch of
power steering pump, and attach eye joint to power steering
pump properly. Tighten eye bolt by hand fully, then torque to
specification.

PRECAUTIONS

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EIS004VI
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 EIS004VJ

Disconnect both battery cables in advance.

Never 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.

HEIGHT DIFFERENCE ADJUSTMENT
If an excessive height difference between glass lid assembly and roof panel is found, adjust in the following
manner:
1. Remove headlining. Refer to EI-38, "
HEADLINING" .
2. Loosen sunroof frame assembly nuts and sunroof bracket bolts.
3. Add shims until gap is within specification "A-A". NOTE:
Temporarily snug nuts and bolts to prevent movement between each adjustment.
4. Tilt glass lid assembly up and down several times to check that it moves and seals properly.
5. Tighten sunroof frame assembly nuts and sunroof bracket bolts. NOTE:
First tighten left front then right rear sunroof frame assembly to prevent uneven torque while tightening
remaining sunroof bracket bolts.
6. Install headlining. Refer to EI-38, "
HEADLINING" .
Removal and InstallationEIS007XH

After any adjustment, check sunroof operation and glass lid assembly alignment.

Handle glass lid assembly with care so not to cause damage.

For easier installation, mark each point before removal.
CAUTION:

Always work with a helper.

Before removal, fully close the glass lid assembly. Then, after removal, do not move the sunroof
motor assembly.

Precautions for Servicing Rear Final DriveEDS0044K

Before starting diagnosis of the vehicle, understand the symptoms well. Perform correct and systematic
operations.

Check for the correct installation status prior to removal or disassembly. When matching marks are
required, be certain they do not interfere with the function of the parts they are applied to.

Overhaul should be done in a clean work area, a dust proof area is recommended.

Before disassembly, completely remove sand and mud from the exterior of the unit, preventing them from
entering into the unit during disassembly or assembly.

Always use shop paper for cleaning the inside of components.

Avoid using cotton gloves or a shop cloth to prevent the entering of lint.

Check appearance of the disassembled parts for damage, deformation, and abnormal wear. Replace
them with new ones if necessary.

Gaskets, seals and O-rings should be replaced any time the unit is disassembled.

Clean and flush the parts sufficiently and blow them dry.

Be careful not to damage sliding surfaces and mating surfaces.

When applying sealant, remove the old sealant from the mating surface; then remove any moisture, oil,
and foreign materials from the application and mating surfaces.

In principle, tighten nuts or bolts gradually in several steps working diagonally from inside to outside. If a
tightening sequence is specified, observe it.

During assembly, observe the specified tightening torque.

Add new differential gear oil, petroleum jelly, or multi-purpose grease, as specified.
