Removal and InstallationNES000IX
REMOVAL
1. Remove tires from vehicle with a power tool.
2. Remove shock absorber. Refer to FSU-28, "
COIL SPRING AND SHOCK ABSORBER" .
3. Remove mounting nut and bolt with a power tool, and then remove upper link from steering knuckle.
4. Remove mounting nuts and bolts, and then remove upper link and stopper rubber from vehicle.
INSPECTION AFTER REMOVAL
Visual Inspection
Check the following:
Upper link and bushing for deformation, cracks or damage. Replace it if a malfunction is detected.
Ball joint boot for cracks or other damage, and also for grease leakage. Replace it if a malfunction is
detected.
Ball Joint Inspection
Manually move ball stud to confirm it moves smoothly with no binding.
Swing Torque Inspection
NOTE:
Before measurement, move ball stud at least ten times by hand to check for smooth movement.
Hook a spring balance at cutout on ball stud. Confirm spring bal-
ance measurement value is within specifications when ball stud
begins moving.
If it is outside the specified range, replace upper link assembly.
Rotating Torque Inspection
Attach mounting nut to ball stud. Make sure that rotating torque
is within specifications with a preload gauge [SST].
If it is outside the specified range, replace upper link assembly.
Axial End Play Inspection
Move tip of ball stud in axial direction to check for looseness.
If it is outside the specified range, replace upper link assembly.
INSTALLATION
Installation is the reverse order of removal. For tightening torque, refer to FSU-25, "Components" .
Perform final tightening of bolts and nuts at the vehicle installation position (rubber bushing) under
unladen conditions with tires on level ground. Check wheel alignment. Refer to FSU-23, "
Wheel Align-
ment Inspection" . Swing torque

PRECAUTIONS
Revision: 2006 January2006 M35/M45
Precautions Necessary for Steering Wheel Rotation After Battery DisconnectNAS0008J
NOTE:
This Procedure is applied only to models with Intelligent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).
Remove and install all control units after disconnecting both battery cables with the ignition knob in the
LOCK position.
Always use CONSULT-II 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 NVIS/IVIS, an electrically controlled steering lock
mechanism 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 power 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.
5. When the repair work is completed, return the ignition switch to the
LOCK position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-II.
Precautions for Procedures without Cowl Top CoverNAS00077
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
General PrecautionsNAS00078
Do not operate the engine for an extended period of time without
proper exhaust ventilation.
Keep the work area well ventilated and free of any flammable
materials. Special care should be taken when handling any flam-
mable or poisonous materials, such as gasoline, refrigerant gas,
etc. When working in a pit or other enclosed area, be sure to
properly ventilate the area before working with hazardous mate-
rials.
Do not smoke while working on the vehicle.

Tow Truck TowingNAS00081
CAUTION:
All applicable state or Provincial (in Canada) laws and local laws regarding the towing operation
must be obeyed.
It is necessary to use proper towing equipment to avoid possible damage to the vehicle during
towing operation. Towing is in accordance with Towing Procedure Manual at dealer.
Always attach safety chains before towing.
When towing, make sure that the transmission, steering system and powertrain are in good order.
If any unit is damaged, dollies must be used.
Never tow an automatic transmission model from the rear (that is backward) with four wheels on
the ground. This may cause serious and expensive damage to the transmission.
2WD MODELS
INFINITI recommends that vehicle be towed with the driving (rear) wheels off the ground or that a dolly be
used as illustrated.
CAUTION:
Never tow automatic transmission models with the rear wheels on the ground or four wheels on
the ground (forward or backward), as this may cause serious and expensive damage to the trans-
mission.
If it is necessary to tow the vehicle with the front wheels raised, always use towing dollies under
the rear wheels.
When towing rear wheel drive models with the front wheels on the ground or on towing dollies:
–Turn the ignition key to the OFF position, and secure the steering wheel in a straight ahead posi-
tion with a rope or similar device.Never secure the steering wheel by turning the ignition key to the
LOCK position. This may damage the steering lock mechanism.
–Move the selector lever to the N (Neutral) position.
When the battery of vehicle equipped with the Intelligent Key system is discharged, your vehicle
should be towed with the front wheels on towing dollies or place the vehicle on a flat bed truck.
If the speed or distance must necessarily be greater, remove the propeller shaft before towing to prevent dam-
age to the transmission.

AWD MODELS
INFINITI recommends that a dolly be used as illustrated when towing AWD models.
CAUTION:
Never tow AWD models with any of the wheels on the ground as this may cause serious and expen-
sive damage to the powertrain.
Vehicle Recovery (Freeing a Stuck Vehicle) NAS00082
FRONT
Securely install the vehicle recovery hook stored with jacking tools.
Make sure that the hook is properly secured in the stored place after
use.
WAR NING :
Stand clear of a stuck vehicle.
Do not spin your tires at high speed. This could cause them
to explode and result in serious injury. Parts of your vehicle
could also overheat and be damaged.
CAUTION:
Tow chains or cables must be attached only to the vehicle
recovery hooks or main structural members of the vehicle.
Otherwise, the vehicle body will be damaged.
Do not use the vehicle tie downs to free a vehicle stuck in sand, snow, mud, etc. Never tow the
vehicle using the vehicle tie downs or recovery hooks.
Always pull the cable straight out from the front of the vehicle. Never pull on the hook at an angle.
Pulling devices should be routed so they do not touch any part of the suspension, steering, brake
or cooling systems.
Pulling devices such as ropes or canvas straps are not recommended for use in vehicle towing or
recovery.
REAR
WAR NING :
Rear hook is not available.

AUTOMATIC TRANSMISSION
To tow a vehicle equipped with an automatic transmission, an appropriate vehicle dolly MUST be placed
under the towed vehicle's drive wheels. Always follow the dolly manufacture's recommendations when using
their product.
If the vehicle is stuck in sand, snow, mud, etc., use the following procedure:
1. Turn off the Vehicle Dynamic Control System.
2. Make sure the area in front and behind the vehicle is clear of obstructions.
3. Turn the steering wheel right and left to clear an area around the front tires.
4. Slowly rock the vehicle forward and backward.
Shift back and forth between R (reverse) and D (drive).
Apply the accelerator as little as possible to maintain the rocking motion.
Release the accelerator pedal before shifting between R and D.
Do not spin the tires above 35 mph (55 km/h).
5. If the vehicle can not be freed after a few tries, contact a professional towing service to remove the vehi-
cle.
