Be careful of the following.
CAUTION:
 When removing the sensor, do not rotate it if possible, and not forcibly pull the sensor harness.
 Before removing front or rear wheel hub, remove wheel sensor to avoid sensor wiring damage.
INSTALLATION
Be certain to tighten bolts to the specified torque. Be careful of the following: Check the inside of the sensor mounting hole for foreign material, the rotor surface for iron chips and other
foreign material, and if anything is non-standard, clean it before installation, or replace it.
 When installing the front sensor, completely push in the strut bracket and body bracket rubber grommets
until they lock so that the sensor harness does not become twisted. In addition, there should be no twists in
the harness when installed. Install the harness so that the painted part faces the outside of the vehicle.
 When installing the rear sensor, completely push in the rubber bracket of the suspension arm bracket and
lock the marking area of the side member harness mount so that the sensor harness will not be twisted. In
addition, there should be no twists in the harness when installed.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001716875
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. 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 whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SR and SB section of this Service Man-
ual.
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 SR 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 har-
ness connectors.
Precaution for Procedure without Cowl Top CoverINFOID:0000000001716876
When performing the procedure after removing cowl top cover, cover
the lower end of windshield.
CautionsINFOID:0000000001716877
 When installing rubber bushings, the final tightening must be carried out under unladen conditions with tires
on ground. Oil might shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
- Unladen conditions mean that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
 After servicing suspension parts, be sure to check wheel alignment.
 Self-lock nuts are not reusable. Always use new ones when installing.

Make sure the mounting conditions (looseness, back lash) of each component and component conditions
(wear, damage) are normal.
INSPECTION OF LOWER BALL JOINT END PLAY
1. Set front wheels in a straight-ahead position. Do not depress brake pedal.
2. Place an iron bar or similar tool between transverse link and steering knuckle.
3. Measure axial end play by prying it up and down.
CAUTION:
Be careful not to damage ball joint boot. Do not damage the installation position by applying
excessive force.
STRUT INSPECTION
Check for oil leakage, damage and replace as necessary.
Wheel Alignment InspectionINFOID:0000000001716891
PRELIMINARY INSPECTION
WARNING:
Always adjust the alignment with the vehicle on a flat surface.
NOTE:
If alignment is out of specification, inspect and replace any damaged or worn rear suspension parts before
making any adjustments.
1. Check and adjust the wheel alignment with the vehicle under unladen conditions. “Unladen conditions”
means that the fuel, coolant, and lubricant are full; and that the spare tire, jack, hand tools and mats are in
their designated positions.
2. Check the tires for incorrect air pressure and excessive wear.
3. Check the wheels for run out and damage. Refer to WT-5, "
Inspection" .
4. Check the wheel bearing axial end play. Refer to FA X - 5 , "
On-Vehicle Inspection and Service" .
5. Check the shock absorbers for leaks or damage.
6. Check each mounting point of the suspension components for any excessive looseness or damage.
7. Check each link, arm, and the suspension member for any damage.
8. Check the vehicle height. Refer to FSU-18, "
Wheelarch Height (Unladen*)" .
GENERAL INFORMATION AND RECOMMENDATIONS
1. A Four-Wheel Thrust Alignment should be performed.
 This type of alignment is recommended for any NISSAN vehicle.
 The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel
is centered.
 The alignment machine itself should be capable of accepting any NISSAN vehicle.
 The alignment machine should be checked to ensure that it is level.
2. Make sure the alignment machine is properly calibrated.
 Your alignment machine should be regularly calibrated in order to give correct information.
 Check with the manufacturer of your specific alignment machine for their recommended Service/Cali-
bration Schedule.
THE ALIGNMENT PROCESS
IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to FSU-17, "Wheel
Alignment (Unladen*)" .
1. When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or
minus, Go/No Go). Do NOT use these indicators. Axial end play : 0 mm (0 in)

 The alignment specifications programmed into your alignment machine that operate these indicators
may not be correct.
 This may result in an ERROR.
2. Some newer alignment machines are equipped with an optional “Rolling Compensation” method to “com-
pensate” the sensors (alignment targets or head units). Do NOT use this “Rolling Compensation”
method.
 Use the “Jacking Compensation” method. After installing the alignment targets or head units, raise the
vehicle and rotate the wheels 1/2 turn both ways.
 See Instructions in the alignment machine you are using for more information.
CAMBER, CASTER AND KINGPIN INCLINATION ANGLES INSPECTION
 Camber, caster, kingpin inclination angles cannot be adjusted.
 Before inspection, mount front wheels onto turning radius gauge. Mount rear wheels onto a stand that has
same height so vehicle will remain horizontal.
Using a CCK Gauge
Install the CCK gauge attachment [SST: KV991040S0] with the following procedure on wheel, then measure
wheel alignment.
1. Remove three wheel nuts, and install the guide bolts to hub bolt.
2. Screw the adapter into the plate until it contacts the plate tightly.
3. Screw the center plate into the plate.
4. Insert the plate assembly on the guide bolt. Put the spring in,
and then evenly screw the three guide bolt nuts. When fastening
the guide nuts, do not completely compress the spring.
5. Place the dent of alignment gauge onto the projection of the
center plate and tightly contact them to measure.
CAUTION:
 If camber, caster, or kingpin inclination angle is outside
the specification, check front suspension parts for wear
and damage. Replace suspect parts if a malfunction is
detected.
 Kingpin inclination angle is reference value, no inspection
is required.
TOE-IN INSPECTION
Measure toe-in using the following procedure.
WARNING:
 Always perform the following procedure on a flat surface.
 Make sure that no person is in front of vehicle before pushing it.
1. Bounce the front of vehicle up and down to stabilize the vehicle height (posture).
2. Push vehicle straight ahead about 5 m (16 ft).Tool number : KV991040S0 ( — )

3. Put a mark on base line of the tread (rear side) of both tires at
the same height of hub center. These are measuring points.
4. Measure distance “A” (rear side).
5. Push vehicle slowly ahead to rotate wheels 180 degrees (1/2
turn).
CAUTION:
If wheels have rotated more than 180 degrees (1/2 turn), try
the above procedure again from the beginning. Never push
vehicle backward.
6. Measure distance “B” (front side).
7. Use the formula below to calculate total toe-in.
 If the total toe-in is outside the specification, adjust toe-in by varying the length of between steering
outer socket and inner socket.
