3. Install balance weight in the position shown.
CAUTION:
• Do not install the inner bala nce weight before installing
the outer balance weight.
• Before installing the balance weight, be sure to clean the mating surface of the road wheel.
• When installing balance weight (1) to road wheel, set it into the grooved area (A) on the inner wall of the road wheel as shown
so that the balance weight cent er (B) is aligned with the bal-
ancer machine indication position (angle) (C).
CAUTION:
• Always use genuine NISSAN adhesive balance weights.
• Balance weights are non-re usable; always replace with
new ones.
• Do not install more than th ree sheets of balance weight.
4. If calculated balance weight value exceeds 50 g (1.76 oz), install two balance weight sheets in line with each other as shown.
CAUTION:
Do not install one balance weight sheet on top another.
5. Start balancer machine again.
6. Install balance weight on inner side of road wheel in the bal- ancer machine indication position (angle).
CAUTION:
Do not install more than two balance weights.
7. Start balancer machine. Make sure that inner and outer residual imbalance values are 5 g (0.17 oz) each or below.
8. If either residual imbalance value exceeds 5 g (0.17 oz), repeat installation procedures.
RotationINFOID:0000000004215548
TIRE ROTATION
• Follow the maintenance schedule for tire rotation service intervals.
Refer to MA-6, "
General Maintenance".
• When installing the wheel, tighten wheel nuts to the specified
torque.
CAUTION:
• Do not include the spare tire when rotating the tires.
• When installing wheels, tighte n them diagonally by dividing
the work two to three times in order to prevent the wheels
from developing any distortion.
• Be careful not to tighten wh eel nut at torque exceeding the
criteria for preventing strain of disc rotor.
• Use NISSAN genuine wheel nuts for aluminum wheels.

Check all of the component mountings for any excessive looseness, or back lash. Check the components for
any excessive wear, damage, or abnormal conditions. Repair or replace the components as necessary.
SHOCK ABSORBER INSPECTION
 Check the shock absorbers for any air l eaks or damage, and replace as necessary.
 Check the hoses for any air leaks or damage, and replace as necessary.

PRELIMINARY INSPECTION
WARNING:
Always adjust the alignm ent with the vehicle on a flat su rface. Use CONSULT-III “EXHAUST SOLE-
NOID” active test to release the air pressure from the rear load leveling air suspension system.
NOTE:
If alignment is out of specificat ion, 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 runout and damage.
4. Check the wheel bearing axial end play.
5. Check the shock absorbers. Refer to RSU-6, "On-Vehicle Inspection and Service"
.
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 RSU-29, "Wheel Alignment (Unladen
*1)" .
