Inspection EES002L2

1. Check tires for wear and improper inflation.

2. Check wheels for deformation, cracks and other damage. If B
deformed, remove wheel and check wheel runout.
a. Remove tire from wheel and mount wheel on a tire balance
machine. C
b. Set dial indicator as shown in the illustration.
Wheel runout (Dial indicator value):
D
Refer to WT-6, "SERVICE DATA AND SPECIFICA-
TIONS (SDS)"

3. Check front wheel bearings for looseness. WT

4. Check front suspension for looseness.
STEEL WHEEL
1. Check tires for wear and improper inflation. F
2. Check wheels for deformation, cracks and other damage. If
deformed, remove wheel and check wheel runout.
a. Remove tire from steel wheel and mount wheel on a tire balance G
machine.
b. Set two dial indicators as shown in the illustration.
H
c. Set each dial indicator to 0.
d. Rotate wheel and check dial indicators at several points around
the circumference of the wheel.
I
e. Calculate runout at each point as shown below.
Radial runout = (A+B)/2 : 0.5 mm (0.020 in)
Lateral runout = (C+D)/2 : 0.8 mm (0.031 in) J
f. Select maximum positive runout value and the maximum nega-
tive value.
Add the two values to determine total runout. K
In case a positive or negative value is not available, use the
maximum value (negative or positive) for total runout.
If the total runout value exceeds the limit, replace steel wheel. L

Balancing Wheels EES002L3

REMOVAL
1. Using releasing agent, remove double-faced adhesive tape from the wheel.
CAUTION:
● Be careful not to scratch the wheel during removal.

● After removing double-faced adhesive tape, wipe clean traces of releasing agent from the
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 wheels.
1. Set wheel on wheel balancer using the center hole as a guide. Start the tire balance machine.
2. When inner and outer imbalance values are shown on the wheel balancer indicator, multiply outer imbal-
ance value by 1.6 to determine balance weight that should be used. Select the outer balance weight with
a value closest to the calculated value and install it to the designated outer position of, or at the desig-
nated angle in relation to the road wheel.
CAUTION:
● Do not install the inner balance weight before installing the outer balance weight.

● Before installing the balance weight, be sure to clean the mating surface of the wheel.

Indicated imbalance 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 g = 35 g (1.23 oz)
37.5 g = 40 g (1.41 oz)

SMA054D

a. Install balance weight in the position shown.

b. When installing balance weight to wheels, set it into the grooved
area on the inner wall of the wheel as shown so that the balance
weight center is aligned with the wheel balancer indication posi-
tion (angle).
CAUTION:
● Always use Genuine NISSAN adhesion balance weights.

● Balance weights are not reusable; always replace with

new ones.
● Do not install more than three sheets of balance weights.

 WHEEL AND TIRE ASSEMBLY

c. If calculated balance weight value exceeds 50 g (1.76 oz), install

two balance weight sheets in line with each other as shown. A
CAUTION:
Do not install one balance weight sheet on top of another.
3. Start wheel balancer again. B
4. Install drive-in balance weight on inner side of road wheel in the
wheel balancer indication position (angle).
CAUTION: C
Do not install more than two balance weights.
5. Start wheel balancer. Make sure that inner and outer residual SMA056D
imbalance values are 5g (0.18 oz) each or below. D
● If either residual imbalance value exceeds 5 g (0.18 oz), repeat installation procedures.

Wheel balance (Maximum allowable imbalance):

WT
Maximum allowable Dynamic (At rim flange) 5 g (0.18 oz) (one side)
imbalance Static 10 g (0.35 oz)

Rotation EES002L4
F

● Follow the maintenance schedule for tire rotation service intervals. Refer to MA-7, "GENERAL MAINTE-
NANCE" .
G
● Do not include the spare tire when rotating the tires.
CAUTION:
When installing wheels, tighten them diagonally by dividing H
the work two to three times in order to prevent the wheels
from developing any distortion.
