d. Wrap an OHP sheet [approximately 70 mm (2.76 in) × 100 mm
(3.94 in)]. Around the edge to avoid damaging rack oil seal
(outer). Install rack oil seal over sheet. Then, pull oil seal along
with OHP sheet until they pass rack edge, and remove OHP
sheet.
e. Install end cover assembly to rack edge, and move rack oil seal
(outer) until it contacts with gear housing assembly.
5. Tighten end cover assembly to specified torque using a 36 mm
(1.42 in) open head (suitable tool).
CAUTION:
Never damage rack assembly. Replace it if damaged
because it may cause fluid leakage.
6. Crimp gear housing assembly at one point using a punch as
shown in the figure so as to prevent end cover assembly from
getting loose after tightening end cover assembly.
7. Apply recommended fluid to O-ring, and then install O-ring to
gear housing assembly.
8. Install gear-sub assembly to gear housing assembly.
CAUTION:
In order to protect oil seal from any damage, insert gear-
sub assembly straightly.
9. Install inner socket and spacer to gear housing assembly with
the following procedure.
a. Apply recommended thread locking sealant into the thread of inner socket.
Use Genuine High Strength Thread Locking Sealant, Loctite 271 or equivalent.
b. Screw inner socket into rack part and tighten at the specified torque.

12. Apply recommended sealant into the thread of adjusting screw
(2 turns thread), and then screw in the adjusting screw until it
reaches height “H” from gear housing assembly measured
before disassembling.
Use Genuine Liquid Gasket, Three Bond 1111B or equiva-
lent.
13. Move rack assembly 10 strokes throughout the full stroke so that
the parts can fit with each other.
14. Adjust pinion rotating torque with the following procedure.
a. Measure pinion rotating torque within ±180° of neutral position
of the rack assembly using Tools. Stop the gear at the point
where highest torque is read.
b. Loosen adjusting screw and retighten to 5.4 N·m (0.55 kg-m, 48
in-lb), and then loosen by 20 to 40°.
c. Measure pinion rotating torque using Tools to make sure that the
measured value is within the standard. Readjust if the value is
outside the standard. Replace steering gear assembly, if the
value is outside the standard after readjusting, or adjusting
screw rotating torque is 5 N·m (0.51 kg-m, 44 in-lb) or less.
d. Apply recommended liquid gasket to inner socket and turn pinion fully to left with inner socket installed to
gear housing assembly.
e. Install dial indicator at 5 mm (0.20 in) (L) from the edge of gear
housing assembly (1), and tooth point.
f. Measure vertical movement of rack assembly when pinion is
turned clockwise with torque of 19.6 N·m (2.0 kg-m, 14 ft-lb).
Readjust adjusting screw angle if the measured value is outside
the standard.
 If reading is outside of the specification, readjust screw angle
with adjusting screw.
CAUTION:
 If reading is still outside of specification, or if the rotating torque of adjusting screw is less
than 5 N·m (0.51 kg-m, 44 in-lb), replace steering gear assembly.
 Never turn adjusting screw more than twice.
 Replace steering gear assembly when adjusting screw is removed or turned more than twice.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003971959
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 AIRBAG” and
“SEAT BELT” 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 performed by
an authorized NISSAN/INFINITI dealer.
 Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SRS AIRBAG”.
 Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.
Precaution Necessary for Steering Wheel Rotation after Battery Disconnect
INFOID:0000000003893541
NOTE:
 Before removing and installing any control units, first turn the push-button ignition switch to the LOCK posi-
tion, then disconnect both battery cables.
 After finishing work, confirm that all control unit connectors are connected properly, then re-connect both
battery cables.
 Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.
This vehicle is equipped with a push-button ignition switch and a steering lock unit.
If the battery is disconnected or discharged, the steering wheel will lock and cannot be turned.
If turning the steering wheel is required with the battery disconnected or discharged, 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. Carry the Intelligent Key or insert it to the key slot and turn the push-button ignition switch to ACC position.
(At this time, the steering lock will be released.)
3. Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.
4. Perform the necessary repair operation.
5. When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering
wheel will lock when the push-button ignition switch is turned to LOCK position.)
6. Perform self-diagnosis check of all control units using CONSULT-III.
