Front Suspension PartsEES0010I
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, then
check ball joint end play. Refer to FSU-15, "
Inspection" .

Make sure that the cotter pin is inserted (4WD only).

Retighten all nuts and bolts to the specified torque.

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.
Front Wheel AlignmentEES0010J
PRELIMINARY INSPECTION
WAR NIN G:
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-4, "
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 rear suspension member for any damage.
8. Check the vehicle height. Refer to FSU-21, "
Wheelarch Height (Unladen*1 )" .

For air leveling vehicles, verify the level using Consult-II memory register 1103 and set to 0 ± 10 mm (0
± 0.39 in) as necessary.
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.Suspension component torques : Refer to FSU-5,
"Components" .

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-21,
"Wheelarch Height (Unladen*1 )" .
1. When displaying the alignment settings, many alignment 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.

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 AND CASTER
1. Measure camber and caster of both the right and left wheels
with a suitable alignment gauge and adjust as necessary to
specification.
2. If outside of the specified value, adjust camber and caster using
the adjusting bolts in the front lower link.
CAUTION:
After adjusting the camber then check the toe-in.
NOTE:
Camber changes about 3' (0.11°) with each graduation of one
adjusting bolt. Refer to table below for examples of lower link
adjusting bolt effect on camber and caster.
3. Tighten the adjusting bolt nuts to specification. Refer to FSU-5, "
Components" . Camber : Refer to FSU-20, "
Wheel Alignment
(Unladen*1 )" .

COIL SPRING AND SHOCK ABSORBERPFP:56210
Removal and InstallationEES0010K
REMOVAL
1. Remove the wheel and tire using power tool.
2. Remove the shock absorber lower bolt using power tool.
3. Remove the three shock absorber upper mounting nuts using
power tool.
4. Remove the coil spring and shock absorber assembly.

Turn steering knuckle out to gain enough clearance for
removal.
INSTALLATION
Installation is in the reverse order of removal.

The step in the shock absorber assembly lower seat faces outside of vehicle.

Tighten all nuts and bolts to specification. Refer to FSU-5, "Components" .

When installing wheel and tire, refer to WT-6, "Rotation" .
Disassembly and AssemblyEES0010L
DISASSEMBLY
1. Set the shock absorber in a vise, then loosen (without removing)
the piston rod lock nut as shown.
CAUTION:
Do not remove piston rod lock nut at this time.
2. Compress the spring using commercial service tool until the
shock absorber mounting insulator can be turned by hand.
WAR NIN G:
Make sure that the pawls of the two spring compressors are
firmly hooked on the spring. The spring compressors must
be tightened alternately and evenly so as not to tilt the
spring.
3. Remove the piston rod lock nut.

Discard the piston rod lock nut, use a new nut for assembly.
INSPECTION AFTER DISASSEMBLY
Shock Absorber Assembly

Check for smooth operation through a full stroke, both compression and extension.

Check for oil leakage on welded or gland packing portions.

Check piston rod for cracks, deformation or other damage and replace if necessary.
Mounting Insulator and Rubber Parts
Check cemented rubber-to-metal portion for separation or cracks. Check rubber parts for deterioration and
replace if necessary.
