INSPECTION AFTER DISASSEMBLY
Joint Cover
Check joint cover protrusion for damage. Replace if there are.
Rack and Pinion Assembly
• Check pinion assembly for damage or wear. Replace as necessary.
• Rotate pinion assembly and check for torque variati on or rattle. Replace steering gear as necessary.
Gear Housing Assembly
Check gear housing assembly for damage or scratches. Replace steering gear as necessary.
Outer Socket and Inner Socket
1. Check ball joint swinging torque.
• Hook a spring balance at the point shown and pull the spring
balance. Make sure that the spring balance reads the speci-
fied value when ball stud and inner socket start to move.
Replace outer socket and inner socket if they are outside the
standard.
2. Ball joint axial end play • Apply an axial load of 490 N (50 kg-f, 111 lb-f) to ball stud.Measure amount of stud movement using a dial gauge, and
then make sure that the value is within the specified range.
Replace outer socket and inner socket if the measured value
is outside the standard.

1. Apply recommended grease to teeth part and bush part of rack assembly, if necessary.
2. Apply recommended grease to back of rack assembly, if necessary.
3. Install inner socket to rack assembly. Torque to specified value while holding the flat portion of the rack next to the inner socket using a suitable tool.
4. Apply recommended grease to inner socket.
5. Decide on the neutral position for the rack assembly.
6. Apply recommended grease to around retainer (3), then install retainer (3), spring (4) and adjusting screw (1) to gear housing
assembly (5).
7. Apply recommended thread locking sealant to the thread (2 turns thread), and then screw in the adjusting screw (1) until it
reaches height “H” from gear housing assembly (5) measured
before disassembling.
8. Tighten lock nut to (2) the specified torque securing it to prevent adjusting screw (1) from freewheeling condition.
9. Move rack assembly 10 strokes throughout the full stroke so that the parts can fit with each other.
10. Using Tools A and B, measure rotating torque of pinion assem- bly. If the measurement is outside of the specified range, read-
just pinion rotating torque. If the measurement is outside of the
specified range for readjust, replace steering gear assembly.
11. Set dial gauge to the back of rack assembly on the pinion assembly side around the center of stroke. Measure displace-
ment of rack under torsional torque of ± 7.8 N·m (0.80 kg-m, 69
in-lb), and then check if it is within the standard value. If the
measurement is outside the standard value, adjust it again. After
the readjustment, if measurement is still outside the standard
value, replace steering gear assembly.
12. Install boot to gear housing assembly and inner socket. Rack stroke “L” : 65.0 mm (2.559 in)

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000005714402
The Supplemental Restraint System such as “A IR 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 w hether 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 inopera tive, 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 performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SRS section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery, and wait at least 3 minu tes before performing any service.
Precaution Necessary for Steering W heel Rotation After Battery Disconnect
INFOID:0000000005397136
NOTE:
• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-
TEM).
• Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK ″ position.
• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-
anism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery pow er is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables. NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC ″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be rotated.
4. Perform the necessary repair operation.
