 PRECAUTIONS

PRECAUTIONS PFP:00001

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER” EES002BN

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 SRS 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 per-
formed by an authorized NISSAN/INFINITI dealer.
● Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS 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
harness connectors.
Precautions EES0022O

● When installing the rubber bushings, the final tightening must be done under unladen condition and with
the tires on level ground. Oil will shorten the life of the rubber bushings, so wipe off any spilled oil immedi-
ately.
● Unladen condition means the fuel tank, engine coolant and lubricants are at the full specification. The
spare tire, jack, hand tools, and mats are in their designated positions.
● After installing suspension components, check the wheel alignment.
● Lock nuts are not reusable. Always use new lock nuts for installation. New lock nuts are pre-oiled, do not
apply any additional lubrication.

Front Suspension Parts EES0022T

Check front suspension parts for excessive play, cracks, wear and
other damage.
● Shake each front wheel to check for excessive play. If looseness
is noted:
– inspect wheel bearing end play. Refer to FAX-5, "WHEEL
BEARING INSPECTION" .
– check ball joint end play. Refer to FSU-15, "Inspection" .
● Make sure that the cotter pin is inserted in drive shaft end (4WD
only).
● Retighten all nuts and bolts to the specified torque. SMA525A

Suspension component torques : Refer to FSU-5,

"Components" .

● Check shock absorber for oil leakage and other damage.

● Check suspension ball joint for grease leakage and ball joint
dust cover for cracks and other damage.

SFA392B

Front Wheel Alignment EES0022U

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 FAX-5, "WHEEL BEARING INSPECTION" .
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-21, "Wheelarch Height (Unladen*1 )" .
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.

Revision: September 2005 FSU-6 2006 Pathfinder

 ON-VEHICLE SERVICE

● 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- A
bration Schedule.
THE ALIGNMENT PROCESS
B
IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to FSU-20, "Wheel
Alignment (Unladen*1)*6" .
1. When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or
minus, Go/No Go). Do NOT use these indicators. C
● The alignment specifications programmed into your alignment machine that operate these indicators
may not be correct.
D
● 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. FSU
● 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. F

CAMBER AND CASTER

1. Measure camber and caster of both the right and left wheels G
with a suitable alignment gauge and adjust as necessary to
specification.
Camber : Refer to FSU-6, "Front Wheel Alignment" . H
NOTE:
Some vehicles may be equipped with straight (non-adjustable)
lower link bolts and washers. In order to adjust camber and I
caster on these vehicles, first replace the lower link bolts and
washers with adjustable (cam) bolts and washers.
SRA096A
J
2. If outside of the specified value, adjust camber and caster using
the adjusting bolts in the front lower link.
K
CAUTION:
After adjusting the camber then check the toe-in.
NOTE:
Camber changes about 3' (0.05°) minutes with each graduation L
of one adjusting bolt. Refer to table below for examples of lower
link adjusting bolt effect on camber and caster.

TOE-IN
WARNING:
● Always perform the following procedure on a flat surface.
● Make sure that no person is in front of the vehicle before pushing it.
1. Bounce the front of vehicle up and down to stabilize the vehicle height (posture).
2. Push the vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of the tread (rear side) of both front tires
at the same height as hub center as shown. These marks are
measuring points.

AFA050

4. Measure the distance “A” on the rear side of the front tires as
shown.
5. Push the vehicle slowly ahead to rotate the wheels 180°
degrees (1/2 a turn).
CAUTION:
If the wheels have rotated more than 180° degrees (1/2
turn), start this procedure again from the beginning. Never
push the vehicle backward.
6. Measure the distance “B” on the front side of the front tires at the
same marks as shown. Total toe-in is calculated as “A” – “B”.
SFA234AC
Total toe-in : Refer to FSU-20, "Wheel Alignment
(Unladen*1)*6" .

7. Adjust the toe-in by varying the length of the steering outer tie-
rods.
a. Loosen the outer tie-rod lock nuts.
b. Adjust the toe-in by screwing the outer tie-rods in or out.
Standard length “L” : Refer to PS-15, "POWER
STEERING GEAR AND LINK-
AGE" .
c. Tighten the outer tie-rod lock nuts to specification.
Lock nut : Refer to PS-15, "Removal and SFA486A

Installation" .

 ON-VEHICLE SERVICE

FRONT WHEEL TURNING ANGLE

NOTE: A
Check front wheel turning angle after the toe-in inspection.
1. Place front wheels on turning radius gauges in straight ahead
position and rear wheels on stands so that vehicle can be level. B
Check the maximum inner and outer wheel turning angles for LH
and RH road wheels.
2. Start engine and run at idle, turn steering wheel all the way right C
and left, measure the turning angle.
Wheel turning angle : Refer to FSU-20, "Wheel
(full turn) Alignment (Unladen*1)*6" . D
● Any turning angles are not adjustable. If any of steering
angles are out of the specification, check if the following parts SFA439BA
are worn or damaged. FSU
– Steering gear
– Steering column
– Front suspension components F
If found that they are worn or damaged, replace them with new ones.
