Changing Differential Gear OilNLS00086
1. Drain oil from drain plug and refill with new gear oil.
(For details, refer to FFD-8, "
Changing Differential Gear Oil" and RFD-9, "Changing Differential Gear Oil"
.)
2. Check oil level.
Balancing Wheels (Bonding Weight Type)NLS00087
REMOVAL
1. Remove inner and outer balance weights from the road wheel.
CAUTION:
Be careful not to scratch the road wheel during removal.
2. Using releasing agent, remove double-faced adhesive tape from the road wheel.
CAUTION:
Be careful not to scratch the road wheel during removal.
After removing double-faced adhesive tape, wipe clean traces of releasing agent from the road
wheel.
WHEEL BALANCE ADJUSTMENT
If a tire balance machine has adhesion balance weight mode settings and drive-in weight mode setting,
select and adjust a drive-in weight mode suitable for road wheels.
1. Set road wheel on wheel balancer using the center hole as a guide. Start the tire balance machine.
2. When inner and outer unbalance values are shown on the wheel balancer indicator, multiply outer unbal-
ance value by 5/3 to determine balance weight that should be used. Select the outer balance weight with
a value closest to the calculated value above and install it to the designated outer position of, or at the
designated angle in relation to the road wheel.
CAUTION:
Do not install the inner balance weight before installing the outer balance weight. Oil grade and Viscosity:
Refer to MA-12, "
RECOMMENDED FLUIDS
AND LUBRICANTS" .
Capacity:
Front final drive (F160A)

CHASSIS AND BODY MAINTENANCE
Revision: 2006 January2006 M35/M45
Before installing the balance weight, be sure to clean the
mating surface of the road wheel.
Indicated unbalance value
5/3 = balance weight to be installed
Calculation example:
23 g (0.81 oz)
5/3 = 38.33 g (1.35 oz) = 40 g (1.41 oz) balance
weight (closer to calculated balance weight value)
Note that balance weight value must be closer to the calculated
balance weight value.
Example:
37.4 = 35 g (1.23 oz)
37.5 = 40 g (1.41 oz)
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 wheel
balancer indication position (angle).
CAUTION:
Always use genuine Nissan adhesion balance weights.
Balance weights are unreusable; always replace with new
ones.
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 weight sheet on top of another.
3. Start wheel balancer again.
4. Install drive-in balance weight on inner side of road wheel in the
wheel balancer indication position (angle).
CAUTION:
Do not install more than two balance weights.
5. Start wheel balancer. Make sure that inner and outer residual
unbalance values are 7.5 g (0.26 oz) each or below.
If either residual unbalance value exceeds 7.5 g (0.26 oz), repeat installation procedures.
Wheel balance (Maximum allowable unbalance):
SMA054D
SEIA0271E
Maximum allowable
unbalanceDynamic (At rim flange) Less than 7 g (0.25 oz) (one side)
Static (At rim flange) Less than 14 g (0.50 oz)
