• When installing front wheel sensor, press rubber gr
ommets of strut bracket and body all the way in
until they get locked, and be careful not to apply a twist to harness. Harness should not be twisted
after installation. (Install it with harness paint ma rk on body side grommet facing front of vehicle,
and the strut side grommet facing outside of vehicle.)
REAR WHEEL SENSOR
Removal CAUTION:
• As much as possible, avoid rotati ng wheel sensor when removing it. Pull wheel sensors out without
pulling on sensor harness.
• Take care to avoid damaging wheel sensor edges or rotor teeth. Remove wheel sensor first before
removing front or rear wheel hub. This is to avo id damage to wheel sensor wiring and loss of sensor
function.
1. Disconnect the rear wheel sensor connector.
2. Remove the rear wheel sensor.
Installation Installation is in the reverse order of removal.
CAUTION:
• When installing, make sure there is no foreign mate rial such as iron chips on and in the mounting
hole of the wheel sensor. Make sure no foreign material has been caught in the sensor rotor. Remove
any foreign material and clean the mount.
• When installing rear wheel sensor, press rubber grommets of suspension arm bracket and harness
of side member all the way in until they get locked , and be careful not to apply a twist to harness.
Harness should not be twisted after installati on. (Aim the paint mark upward of vehicle.)

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 al l control units using CONSULT-III.
Precaution for Procedur e without Cowl Top Cover INFOID:0000000004305858
When performing the procedure after removing cowl top cover, cover
the lower end of windshield.
Cautions INFOID:0000000004305859
• When installing rubber bushings, the final tightening mu st 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 l ubricant 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. A lways use new ones when installing. WEIA0178E

FRONT SUSPENSION ASSEMBLY
On-Vehicle Inspection and Service INFOID:0000000004305863
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 bet ween 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 Inspection INFOID:0000000004305864
PRELIMINARY INSPECTION WARNING:
Always adjust the alignment with the vehicle on a flat surface.
NOTE:
If alignment is out of specification, inspect and r eplace 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-6, " Inspection " .
4. Check the wheel bearing axial end play. Refer to FAX-6, " 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-19, " Wheelarch Height (Unladen*) " .
GENERAL INFORMATION AND RECOMMENDATIONS 1. A Four-Wheel Thrust Alignment should be performed. • This type of alignment is re commended 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 ca pable 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 calib rated in order to give correct information.
• Check with the manufacturer of your specific a lignment 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 alignm ent machines use “indicators”: (Green/red, plus or
minus, Go/No Go). Do NOT use these indicators.
• The alignment specifications programmed into your alignment machine that operate these indicators
may not be correct. Axial end play : 0 mm (0 in)
