GENERAL MAINTENANCE
Revision: 2007 April2007 M35/M45
GENERAL MAINTENANCEPFP:00000
Explanation of General MaintenanceNLS0007A
General maintenance includes those items which should be checked during the normal day-to-day operation
of the vehicle. They are essential if the vehicle is to continue operating properly. The owners can perform
checks and inspections themselves or they can have their INFINITI dealers do them.
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise specified.
ItemReference page
TiresCheck the pressure with a gauge, including the spare, at least once a month
and always prior to a long distance trips. Adjust to the specified pressure if
necessary. Check carefully for damage, cuts or excessive wear.—
Wheel nutsWhen checking the tires, make sure no nuts are missing, and check for any
loose nuts. Tighten if necessary.—
WindshieldClean the windshield on a regular basis. Check the windshield at least every
six months for cracks or other damage. Repair as necessary.—
Tire rotationTires should be rotated every 12,000 km (7,500 miles).MA-35
Wheel alignment and
balanceIf the vehicle pulls to either side while driving on a straight and level road, or if
you detect uneven or abnormal tire wear, there may be a need for wheel align-
ment. If the steering wheel or seat vibrates at normal highway speeds, wheel
balancing may be needed.MA-33,
FSU-6
(2WD),
FSU-24
(AWD)
Windshield wiper
bladesCheck for cracks or wear if they do not wipe properly. —
Doors and engine
hoodCheck that all doors and the engine hood operate smoothly as well as the
trunk lid. Also make sure that all latches lock securely. Lubricate if necessary.
Make sure that the secondary latch keeps the hood from opening when the pri-
mary latch is released.
When driving in areas using road salt or other corrosive materials, check lubri-
cation frequently.MA-38
LampsMake sure that the headlamps, stop lamps, tail lamps, turn signal lamps, and
other lamps are all operating properly and installed securely. Also check head-
lamp aim. Clean the headlamps on a regular basis. —

PRECAUTIONS
Revision: 2007 April2007 M35/M45
Precautions for Steering SystemNGS000D1

In case of removing steering gear assembly, make the final tightening with grounded and unloaded vehi-
cle condition, and then check wheel alignment.

Observe the following precautions when disassembling.
–Before disassembly, thoroughly clean the outside of the unit.
–Disassembly should be done in a clean work area. It is important to prevent the internal parts from becom-
ing contaminated by dirt or other foreign matter.
–For easier and proper assembly, place disassembled parts in order on a parts rack.
–Use nylon cloth or paper towels to clean the parts; common shop rags can leave lint that might interfere
with their operation.
–Do not reuse non-reusable parts.
–Before assembling, apply the specified grease to the directed parts.

STEERING WHEEL
Revision: 2007 April2007 M35/M45
STEERING WHEELPFP:48430
On-Vehicle Inspection and ServiceNGS000D8
CHECKING CONDITION OF INSTALLATION

Check installation conditions of steering gear assembly, front suspension assembly, axle and steering col-
umn assembly.

Check if movement exists when steering wheel is moved up and down, to the left and right and to the axial
direction.

Check steering gear assembly mounting bolts and nut for looseness. Refer to PS-19, "COMPONENTS" .
CHECKING STEERING WHEEL PLAY

Turn steering wheel so that front wheels come to the straight-ahead position. Start engine and lightly turn
steering wheel to the left and right until front wheels start to move. Measure steering wheel movement on
the outer circumference.

When the measurement value is outside the standard value, check backlash for each joint of steering col-
umn assembly and installation condition of steering gear assembly.
CHECKING NEUTRAL POSITION STEERING WHEEL

Make sure that steering gear assembly, steering column assembly and steering wheel are installed in the
correct position.

Perform neutral position inspection after wheel alignment. Refer to FSU-6, "Wheel Alignment Inspection"
(2WD), FSU-24, "Wheel Alignment Inspection" (AWD).

Set vehicle to the straight-ahead position and confirm steering wheel is in the neutral position.

Loosen outer socket lock nut and turn inner socket to left and right equally to make fine adjustments if
steering wheel is not in the neutral position.
CHECKING STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating temperature. [Make sure temperature of fluid is
approximately 50 to 80°C (122 to 176°F).]
4. Check steering wheel turning force when steering wheel has
been turned 540° from neutral position.
NOTE:
Multiply the distance (L) from the hook of spring balance to the
center of steering wheel by the measurement value with a spring
balance.
5. If steering wheel turning force is out of the specification, check
rack sliding force and relief hydraulic pressure of oil pump.
Regarding relief hydraulic pressure of oil pump, refer to PS-30,
"CHECKING RELIEF OIL PRESSURE" .
a. Disconnect lower joint and steering knuckle from steering gear assembly. Refer to PS-13, "
COMPO-
NENTS" , FAX-5, "COMPONENT" .
b. Start and run engine at idle to make sure steering fluid has reached normal operating temperature.Steering wheel axial end play : 0 mm (0 in)
Steering wheel play : 0 – 35 mm (0 – 1.38 in)
Steering wheel turning force
: 7.45 N·m (0.76 kg-m, 66 in-lb)

Removal and InstallationNGS000D9
REMOVAL
NOTE:
When reconnecting spiral cable, fix cable with a tape so that fixing case and rotating part keep aligned. This
will omit neutral position alignment procedure during spiral cable installation.
1. Set vehicle to the straight-ahead position.
2. Remove driver air bag module. Refer to SRS-42, "
DRIVER AIR BAG MODULE" .
3. Remove steering wheel lock nut after steering is locked.
4. Remove steering wheel with the steering wheel puller [SST].
INSTALLATION
Installation is the reverse order of removal. For tightening torque, refer to PS-13, "COMPONENTS" .
NOTE:
Check the spiral cable neutral position after replacing or rotating spiral cable. Refer to SRS-44, "
INSTALLA-
TION" .
CAUTION:
Do not twist spiral cable freely on excessively after it becomes tight (doing so may cause the cable to
be turn off).

POWER STEERING GEAR AND LINKAGE
Revision: 2007 April2007 M35/M45
8. Remove steering hydraulic piping bracket from front suspension member. Refer to PS-39, "HYDRAULIC
LINE" .
9. Remove power steering solenoid valve harness connector. Refer to PS-21, "
COMPONENTS" .
10. Remove rack stay (2WD) or front cross bar (AWD). Refer to FSU-8, "
Components" , FSU-26, "Compo-
nents" .
11. Remove mounting bolts and nuts of steering gear assembly, and then remove steering gear assembly
from vehicle.
INSTALLATION
Installation is the reverse order of removal. For tightening torque, refer to PS-19, "COMPONENTS" .

When installing lower joint to steering gear assembly, follow the procedure listed below.
–Set rack of steering gear in the neutral position.
NOTE:
To get the neutral position of rack, turn gear-sub assembly and measure the distance of inner socket, and
then measure the intermediate position of the distance.
–Align rear cover cap projection (A) with the marking position (B)
of gear housing assembly.
–Install slit part of lower joint (C) aligning with the projection (A) of
rear cover cap (1). Make sure that the slit part of lower joint (C)
is aligned with both the projection (A) of rear cover cap (1) and
the marking position (B) of gear housing assembly.

After installation, bleed air from the steering hydraulic system.
Refer to PS-8, "
Air Bleeding Hydraulic System" .

Perform final tightening of nuts and bolts on each part under
unladen conditions with tires on level ground when removing
steering gear assembly. Check wheel alignment. Refer to FSU-
6, "Wheel Alignment Inspection" , FSU-24, "Wheel Alignment
Inspection" .

Adjust neutral position of steering angle sensor after checking wheel alignment. Refer to BRC-6, "Adjust-
ment of Steering Angle Sensor Neutral Position" .
INSPECTION AFTER INSTALLATION
Make sure that steering wheel operates smoothly by turning several times from full left stop to full right stop.
