INSTALLATION

Installation is the reverse order of the removal. For tightening torque, refer to FSU-7, "Components" .
NOTE:
Do not reuse non-reusable parts.

Perform final tightening of each of parts under unladen conditions, which were removed when removing
coil spring and strut. Check the wheel alignment. Refer to FSU-5, "
Wheel Alignment Inspection" .

Adjust neutral position of steering angle sensor after checking the wheel alignment for models with VDC.
Refer to BRC-40, "
Adjustment of Steering Angle Sensor Neutral Position" .

Check wheel sensor harness for proper connection. Refer to BRC-33, "WHEEL SENSORS" .

Be sure that the identification letters on mounting insulator face
in the direction shown in the figure, and then install strut assem-
bly to the vehicle.
Disassembly and AssemblyBES0003P
DISASSEMBLY
CAUTION:
Do not damage strut piston rod when removing components from strut.
1. Install strut attachment [SST] to strut and secure it in a vise.
CAUTION:
Wrap a shop cloth around strut to protect it from damage
when installing strut attachment [SST] to strut.
2. Compress coil spring between upper rubber seat and lower rub-
ber seat (strut) using spring compressor (commercial service
tool) until coil spring is free.
CAUTION:
Start compressing coil spring after making sure that the
compressor is completely attached to coil spring.
3. Make sure that coil spring with the compressor is free between
spring upper rubber seat and lower spring seat (strut), and then
remove piston rod lock nut while securing the end of piston rod
so as not to rotate piston rod.
4. Remove mounting insulator bracket, mounting bearing, spring
upper seat, spring upper rubber seat, bound bumper from strut.

PRECAUTIONSPFP:00001
DescriptionBAS0006Z
Observe the following precautions to ensure safe and proper servicing. These precautions are not
described in each individual section.
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BAS00070
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:

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 for NATS (NISSAN ANTI-THEFT SYSTEM)BAS00071
NATS will immobilize the engine if someone tries to start it without the registered key of NATS.
Both of the originally supplied ignition key IDs have been NATS registered.
The security indicator is located on the instrument panel. The indicator blinks when the immobilizer system is
functioning.
Therefore, NATS warns outsiders that the vehicle is equipped with the anti-theft system.

When NATS detects trouble, the security indicator lamp lights up while ignition switch is in "ON" position.
This lighting up indicates that the anti-theft is not functioning, so prompt service is required.

When servicing NATS (trouble diagnoses, system initialization and additional registration of other NATS
ignition key IDs), CONSULT-II hardware and CONSULT-II NATS software is necessary.
Regarding the procedures of NATS initialization and NATS ignition key ID registration, refer to CONSULT-
II operation manual, NATS.
Therefore, CONSULT-II NATS software (program card and operation manual) must be kept strictly con-
fidential to maintain the integrity of the anti-theft function.

When servicing NATS (trouble diagnoses, system initialization and additional registration of other NATS
ignition key IDs), it may be necessary to re-register original key identification. Therefore, be sure to
receive all keys from vehicle owner. A maximum of four or five key IDs can be registered into NATS.

When failing to start the engine first time using the key of NATS, start as follows.
1. Leave the ignition key in "ON" position for approximately 5 seconds.
2. Turn ignition key to "OFF" or "LOCK" position and wait approximately 5 seconds.
3. Repeat step 1 and 2 again.
4. Restart the engine while keeping the key separate from any others on key-chain.

PRECAUTIONS

Precautions for Engine OilsBAS0008H
Prolonged and repeated contact with used engine oil may cause skin cancer. Try to avoid direct skin contact
with used oil.
If skin contact is made, wash thoroughly with soap or hand cleaner as soon as possible.
HEALTH PROTECTION PRECAUTIONS

Avoid prolonged and repeated contact with oils, particularly used engine oils.

Wear protective clothing, including impervious gloves where practicable.

Do not put oily rags in pockets.

Avoid contaminating clothes, particularly underpants, with oil.

Heavily soiled clothing and oil-impregnated footwear should not be worn. Overalls must be cleaned regu-
larly.

First aid treatment should be obtained immediately for open cuts and wounds.

Use barrier creams, applying them before each work period, to help the removal of oil from the skin.

Wash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help). Prepa-
rations containing lanolin replace the natural skin oils which have been removed.

Do not use gasoline, kerosene, diesel fuel, gas oil, thinners or solvents for cleaning skin.

If skin disorders develop, obtain medical advice without delay.

Where practical, degrease components prior to handling.

Where there is a risk of eye contact, eye protection should be worn, for example, chemical goggles or face
shields; in addition an eye wash facility should be provided.
Precautions for Air Conditioning BAS0008I
Use an approved refrigerant recovery unit any time the air conditioning system must be discharged. Refer to
ATC/MTC section “HFC-134a (R-134a) Service Procedure”, “REFRIGERANT LINES” for specific instructions.
