7. Install the boot securely into the grooves (indicated by * marks)
as shown.
CAUTION:
If there is grease on boot mounting surfaces (indicated by *
marks) of shaft and housing, boot may come off. Remove
all grease from surfaces.
8. Check that the boot installation length “L” is the length indicated
below. Insert a suitable tool into the large end of the boot, as
shown. Bleed air from the boot to prevent boot deformation.
CAUTION:
• The boot may break if the boot installation length is less than the specified value.
• Do not contact inside surface of boot with tip of the suitable tool.
9. Secure the large and small ends of the boot with the new boot
bands as shown.
NOTE:
Discard the old boot bands and use new ones for assembly.
10. After installing the sliding joint housing to the drive shaft, rotate the boot to check that the boot is posi-
tioned correctly. If the boot is not positioned correctly, reposition the boot and secure the boot using a new
boot band.
Wheel Side
1. Insert the Genuine NISSAN Grease or equivalent, into the joint
sub-assembly serration hole until the grease begins to ooze
from the ball groove and serration hole. Refer to MA-10
. After
inserting the grease, use a shop cloth to wipe off the grease that
has oozed out.
2. Wrap the serrated part of the drive shaft with tape. Install the
boot band and boot onto the shaft. Do not damage the boot.
NOTE:
Discard the old boot band and boot and use a new one for
assembly.

ON-VEHICLE SERVICE
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.
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”.
7. Adjust the toe-in by varying the length of the steering outer
socket.
a. Loosen the outer tie-rod lock nuts.
b. Adjust the toe-in by screwing the outer tie-rods in or out.
c. Tighten the outer tie-rod lock nuts to specification.
FRONT WHEEL TURNING ANGLE
NOTE:
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.
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
and left, measure the turning angle.
• Any turning angles are not adjustable. If any of steering angles
are out of the specification, check if the following parts are
worn or damaged.

Precaution for Multiport Fuel Injection System or Engine Control SystemINFOID:0000000003531474
• Before connecting or disconnecting any harness connector for the
multiport fuel injection system or ECM:
Turn ignition switch to “OFF” position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
• Before disconnecting pressurized fuel line from fuel pump to injec-
tors, be sure to release fuel pressure.
• Be careful not to jar components such as ECM and mass air flow
sensor.
Precaution for HosesINFOID:0000000003531475
HOSE REMOVAL and INSTALLATION
• To prevent damage to rubber hose, do not pry off rubber hose with
tapered tool or screwdriver.
• To reinstall the rubber hose securely, make sure of hose insertion
length and clamp orientation. (If tube is equipped with hose stop-
per, insert rubber hose into tube until it butts up against hose stop-
per.)
HOSE CLAMPING
• If old rubber hose is re-used, install hose clamp in its original posi-
tion (at the indentation where the old clamp was). If there is a trace
of tube bulging left on the old rubber hose, align rubber hose at
that position.
• Discard old clamps; replace with new ones.

HEADLAMP (FOR USA)
• to BCM terminal 38.
Ground is supplied
• to BCM terminal 67
• through grounds M57, M61 and M79, and
• to IPDM E/R terminals 38 and 59
• through grounds E9, E15 and E24.
Low Beam Operation
With the lighting switch in 2ND position, the BCM receives input requesting the headlamps to illuminate. This
input is communicated to the IPDM E/R across the CAN communication lines. The CPU of the IPDM E/R con-
trols the headlamp low relay coil. When energized, this relay directs power
• through 15A fuse (No. 41, located in the IPDM E/R)
• through IPDM E/R terminal 54
• to front combination lamp RH terminal 5, and
• through 15A fuse (No. 40, located in the IPDM E/R)
• through IPDM E/R terminal 52
• to front combination lamp LH terminal 5.
Ground is supplied
• to front combination lamp LH and RH terminal 1
• through grounds E9, E15 and E24.
With power and ground supplied, low beam headlamps illuminate.
High Beam Operation/Flash-to-Pass Operation
With the lighting switch in 2ND position and placed in HIGH or PASS position, the BCM receives input request-
ing the headlamp high beams to illuminate. This input is communicated to the IPDM E/R across the CAN com-
munication lines. The CPU of the combination meter controls the ON/OFF status of the HIGH BEAM indicator.
The CPU of the IPDM E/R controls the headlamp high relay coil. When energized, this relay directs power
• through 10A fuse (No. 34, located in the IPDM E/R)
• through IPDM E/R terminal 56
• to front combination lamp RH terminal 6, and
• through 10A fuse (No. 35, located in the IPDM E/R)
• through IPDM E/R terminal 55
• to front combination lamp LH terminal 6.
Ground is supplied
• to front combination lamp LH and RH terminal 2
• through grounds E9, E15 and E24.
With power and ground supplied, the high beam headlamps illuminate.
XENON HEADLAMP
Xenon type headlamp is adopted to the low beam headlamps. Xenon bulbs do not use a filament. Instead,
they produce light when a high voltage current is passed between two tungsten electrodes through a mixture
of xenon (an inert gas) and certain other metal halides. In addition to added lighting power, electronic control
of the power supply gives the headlamps stable quality and tone color.
Following are some of the many advantages of the xenon type headlamp.
• The light produced by the headlamps is a white color comparable to sunlight that is easy on the eyes.
• Light output is nearly double that of halogen headlamps, affording increased area of illumination.
• The light features a high relative spectral distribution at wavelengths to which the human eye is most sensi-
tive. This means that even in the rain, more light is reflected back from the road surface toward the vehicle,
for added visibility.
• Power consumption is approximately 25 percent less than halogen headlamps, reducing battery load.
BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 2ND position (ON), and the ignition switch is turned
from ON or ACC to OFF, the battery saver control feature is activated.
Under this condition, the headlamps remain illuminated for 5 minutes, unless the combination switch (lighting
switch) position is changed. If the combination switch (lighting switch) position is changed, then the headlamps
are turned off.
AUTO LIGHT OPERATION
Refer to LT-34, "System Description" for auto light operation.
