ALUMINUM WHEEL

1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If

deformed, remove wheel and check wheel runout.

CAUTION:

Do not use center hole cone-type clamping machines to

hold the wheel assembly during tire removal/installation or

balancing or damage to the wheel paint, cladding or chrome

may result. Use only rim-type or universal lug-type clamp-

ing machines to hold the wheel assembly during servicing.

a. Remove tire from wheel and mount wheel on a balancer

machine.

b. Set dial indicator as shown. Refer to

WT-53, "Road Wheel"

.

3. Check front wheel bearings for looseness.
4. Check front suspension for looseness.

STEEL WHEEL

1. Check tires for wear and improper inflation.
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 on a balancer machine.
b. Set two dial indicators as shown.
c. Set each dial indicator to 0.
d. Rotate wheel and check dial indicators at several points around

the circumference of the wheel.

e. Calculate runout at each point as shown.

f.

Select maximum positive runout value and the maximum nega-

tive value.

Add the two values to determine total runout. In case a positive

or negative value is not available, use the maximum value (neg-

ative or positive) for total runout. If the total runout value

exceeds the limit, replace the steel wheel.

Adjustment

INFOID:0000000009483106

BALANCING WHEELS (ADHESIVE WEIGHT TYPE)

Preparation Before Adjustment

Remove inner and outer balance weights from the road wheel. 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 all traces of releasing agent from the road

wheel.

Wheel Balance Adjustment

• If a balancer machine has an adhesive weight mode setting, select the adhesive weight mode setting and

skip Step 2. below. If a balancer machine only has the clip-on (rim flange) weight mode setting, follow Step 2.

to calculate the correct size adhesive weight.

1. Set road wheel on balancer machine using the center hole as a guide. Start the balancer machine.
2. For balancer machines that only have a clip-on (rim flange) weight mode setting, follow this step to calcu-

late the correct size adhesive weight to use. When inner and outer imbalance values are shown on the

balancer machine indicator, multiply outer imbalance value by 5/3 (1.67) to determine balance weight that

should be used. Select the outer balance weight with a value closest to the calculated value above and

install in to the designated outer position of, or at the designated angle in relation to the road wheel.

a. Indicated imbalance value

× 5/3 = balance weight to be installed

Calculation example:

23 g (0.81 oz)

× 5/3 (1.67) = 38.33 g (1.35 oz) ⇒ 40 g (1.41 oz)

balance weight (closer to calculated balance weight value)

NOTE:

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)

3. Install balance weight in the position shown.

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 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 center (B) is aligned with the bal-

ancer machine indication position (angle) (C).

CAUTION:

• Always use Genuine NISSAN adhesive balance weights.

• Balance weights are non-reusable; always replace with

new ones.

• Do not install more than three 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.

TIRE ROTATION

• Follow the maintenance schedule for tire rotation service intervals.

Refer to

XX-XX, "*****"

.

• 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, tighten 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 wheel nut at torque exceeding the

criteria for preventing strain of disc rotor.

• Use NISSAN genuine wheel nuts for aluminum wheels.

• Perform the ID registration, after tire rotation. Refer to

XX-XX, "*****"

.
