a. Install balance weight in the position shown in the figure at right.
b. When installing balance weight to road wheels, set it into the grooved area on the inner wall of the road wheel as shown in the
figure so that the balance weight center is aligned with the tire
balance machine indication position (angle).
CAUTION:
 Always use genuine NISSAN adhesion balance weights.
 Balance weights are unreusable; always replace with newones.
 Do not install more than three sheets of balance weight.
c. If calculated balance weight value exceeds 50 g (1.76 oz), install two balance weight sheets in line with each other (as shown in
the figure).
CAUTION:
Do not install one balance weig ht sheet on top of another.
3. Start tire balance machine again.
4. Install drive-in balance weight on inner side of road wheel in the tire balance machine indication position (angle).
CAUTION:
Do not install more than two balance weights.
5. Start tire balance machine. Make sure that inner and outer resid- ual unbalance values are 5.0 g (0.18 oz) each or below.
 If either residual unbalance value exceeds 5.0 g (0.18 oz), repeat installation procedures.
Tire RotationINFOID:0000000001328927
 After rotation the tires, adjust the tire pressure.
 Retighten the wheel nuts when the vehicle has been driven for
1,000 km (600 miles) (also in cases of a flat tire, etc.).
CAUTION:
 Do not include the T-type 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 nu ts for aluminum wheels.

FRONT PROPELLER SHAFT
 As shown in the figure, while fixing yoke on one side, check axialplay of joint. If outside the standard, replace propeller shaft assem-
bly.
 Check propeller shaft for bend and damage. If damage is detected, replace propeller shaft assembly.
CAUTION:
Never disassemble joints.
INSTALLATION
Note the following, install in the reverse order of removal.
 Align matching marks to install propeller shaft to final drive com-panion flange, and then tighten to specified torque. Refer to PR-4,
"Component".
CAUTION:
Never reuse the bolts.
 After assembly, perform a driving test to check propeller shaft vibration. If vibration occurred, separate propeller shaft from final
drive or transfer. Reinstall companion flange after rotating it by 90,
180, 270 degrees. Then perform driving test and check propeller
shaft vibration again at each point. Journal axial play : 0 mm (0 in)

flanges, and then tighten to specified torque. Refer to PR-8, "
Component".
 Install center bearing mounting bracket (Upper) with its arrow mark
facing forward.
 Adjust position of mounting bracket sliding back and forth to pre- vent play in thrust direction of center bearing insulator. Install
bracket to vehicle.
 After assembly, perform a driving test to check propeller shaft vibration. If vibration occurred, separate propeller shaft from final
drive. Reinstall companion flange after rotating it by 60, 120, 180,
240, 300 degrees. Then perform driving test and check propeller
shaft vibration again at each point.
