REAR SUSPENSION ASSEMBLY
InspectionINFOID:0000000012431921
COMPONENT PART
Check the mounting conditions (looseness, backlash) of each component. Verify the component conditions
(wear, damage) are normal.
SHOCK ABSORBER
Check the shock absorber for oil leaks or damage. Replace the components if necessary.

WHEEL ALIGNMENT
WHEEL ALIGNMENT
InspectionINFOID:0000000012431922
DESCRIPTION
Measure the wheel alignment under unladen conditions.
NOTE:
“Unladen conditions” means that fuel, engine coolant, and lubricants are full. Spare tire, jack, hand tools and
mats are in designated positions.
PRELIMINARY
Check the following:
1. Tires for improper air pressure and wear.
2. Road wheels for runout. Refer to WT-44, "
Inspection".
3. Wheel bearing axial end play. Refer to RAX-10, "
Wheel Bearing".
4. Shock absorber operation.
5. Each mounting part of suspension for looseness and deformation.
6. Rear suspension beam for cracks, deformation, and other damage.
7. Vehicle height (posture).
GENERAL INFORMATION AND RECOMMENDATIONS
1. A Four-Wheel Thrust Alignment should be performed. • This type of alignment is recommended for any NISSAN/INFINITI 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 capabl e of accepting any NISSAN/INFINITI 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 al ignment machine for their recommended Service/Cali-
bration Schedule.
THE ALIGNMENT PROCESS
IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to RSU-15, "Wheel
Alignment (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. Most camera-type alignment machines are equipped with both "Rolling Compensation" method and optional "Jacking Compensation" method to "com pensate" the alignment targets or head units.
"Rolling Compensation" is the preferred method.
• If using the "Rolling Compensation" method, after installing the alignment targets or head units, push or pull on the rear wheel to move the vehicle. Do not push or pull the vehicle body.
• If using the "Jacking Compensation" method, after in stalling the alignment targets or head units, raise
the vehicle and rotate the wheels 1/2 turn both ways.
NOTE:
Do not use the "rolling compensation" if you are using sensor-type alignment equipment.
• Follow all instructions for the alignment machine you're using for more information.
CAMBER INSPECTION
• Measure camber of both right and left wheels with a suitable alignment gauge.
• If it is out of the specificati on value, inspect and replace any damaged or worn rear suspension parts.
Camber : Refer to RSU-15, "
Wheel Alignment
(Unladen*1)".

rod.
4. Remove the washer and the bushing.
5. Set a suitable jack under the rear suspension beam. CAUTION:
• At this step, the jack must be set only for supp orting the removal procedure. For details on jack-
ing up the vehicle, refer to GI-28, "
Garage Jack and Safety Stand".
• Do not damage the rear suspension beam with the jack.
• Make sure the rear suspension beam is stable when using the jack.
6. Remove the lower shock absorber bolt.
7. Remove the rear shock absorber.
8. Remove the bushing, the distance tube, the washer, the bound bumper cover, and the bound bumper
from the shock absorber.
9. Inspect the components. Refer to RSU-9, "
Inspection".

INSTALLATION
Installation is in the reverse order of removal.
• To install the bushings (1), securely insert the protrusion (A) into the hole in the vehicle body.
• Install the washer (1) in the direction shown.
• Perform the final tightening of the bolts and nuts under unladen conditions with the tires on level ground.
• Hold the tip (A) of the piston rod. Tighten the piston rod lock nut (1) to the specification.
CAUTION:
Do not reuse the piston rod lock nut.
• When installing the cap, securely engage the cap groove (A) with the flange on the vehicle body.
• After replacing the shock absorber, always follow t he disposal procedure to discard the old shock absorber.
Refer to RSU-10, "
Disposal".

REAR SHOCK ABSORBER
Shock Absorber
Check the following items and replace the parts if necessary.
• Check the shock absorber for oil leaks, deformation, cracks, and other damage.
• Check the piston rod for damage, uneven wear, and distortion.
Bound Bumper, Bushing
Check for cracks and damage. Replace the parts if necessary.
Washer, Bound Bumper Cover, Distance Tube
• Check for cracks and damage. Replace the parts if necessary.
DisposalINFOID:0000000012431926
1. Set the shock absorber horizontally with the piston rod fully extended.
2. Drill a 2 – 3 mm (0.08 – 0.12 in) hole at the position ( ) from thetop as shown to release gas gradually.
CAUTION:
• Wear eye protection (safety glasses).
• Wear gloves.
• Be careful with metal chips or oil blown out by the com-pressed gas.
NOTE:
• Drill vertically in this direction ( ) directly to the outer tube avoiding brackets.
• The gas is clear, colorless, odorless, and harmless.
3. Position the drilled hole downward and drain oil by moving the piston rod several times. CAUTION:
Dispose of drained oil according to the law and local regulations.
