WHEEL BALANCE ACCURACY

M13101000017USA0000010000

PURPOSE

This section contains tips and procedures for
achieving accurate wheel balance. Steering wheel

vibration and/or body shake can result if any of these
procedures are not carefully observed.

WHEEL AND TIRE

31-3

WHEEL AND TIRE DIAGNOSIS

1.

Wheels and tires must be properly mounted on a
balancer in order to achieve correct balance.
Centering the wheel on the shaft of the balancer is
essential for proper mounting.

2.

Off-the-car wheel balancers must be calibrated
periodically to ensure good balancing results. An
inaccurately calibrated balancer could cause
unnecessary replacement of tires, shocks,
suspension components, or steering components.

Check your balancer's calibration approximately
every 100 balances. Your wheel balancer's instruction
manual should include calibration procedures. If the
calibration procedures specifically for your balancer
are missing, use the generic steps in this section for
zero calibration, static balance, and dynamic balance
checks. The wheel balancer calibration checks are
also described in the flowchart. (Refer to P.31-6.)

PROCEDURE Balancing Tips

1.

Confirm that the balancer's cone and the wheel
mounting cone are undamaged and free of dirt and
rust.

2.

On this vehicle, the wheel's center hole on the hub
side has a chamfered edge. Use a back-mounting
cone on your wheel balancer to center the wheel on
the balancer shaft.

3.

Install a wheel mounting cone. The appropriate size
cone for this vehicle is 67.0 mm (2.64 inches).

4.

Before balancing the wheel, remove any wheel
weights from both sides. Also check both sides for
any damage.

5.

When installing wheel weights, hammer them at a
straight (not diagonal) angle.

Confirming Proper Balance

1.

After balancing the wheel, loosen the wing nut and
turn the wheel 180 degrees against the balancer's

hub. Then re-tighten the wing nut and check the
balance again. Repeat wheel balance if necessary.

2.

Turn the wheel again 180 degrees against the
balancer's hub. If the wheel becomes out-of-
balance each time it is turned against the balancer's
hub, the wheel balancer may require calibration.

Wheel Balancer Calibration Checks

1.

Mount an undamaged original-equipment alloy rim
and tire assembly (wheel) onto your off-the-car
wheel balancer. Balance the wheel.

2.

Zero Calibration Check
Loosen the balancer wing nut, rotate the wheel a
half-turn (180 degrees), and retighten the nut.
Recheck the balance.

｠

If the imbalance is 5 g (0.18 ounce) or less, the
zero calibration is OK. Rebalance the wheel, then
go to Step 4 to check static balance.

｠

If the imbalance is more than 5 g (0.18 ounce), go
to Step 3.

3.

Loosen the balancer wing nut, rotate the wheel 1/4
turn (90 degrees), and retighten the nut. Recheck
the wheel balance.

｠

If the imbalance is 5 g (0.18 ounce) or less, the
wheel may not be centered on the balancer, or
the balancing cones, the cup, and/or wing nut are
damaged, dirty, or inappropriate for the wheel.
You may need to refer to the balancer
manufacturer's instructions to verify the correct
attachments. After making the necessary
corrections, recheck the wheel balance. If OK,
then go to Step 4.

WHEEL AND TIRE

WHEEL AND TIRE DIAGNOSIS

｠

If the imbalance is more than 5 g (0.18 ounce),
the balancer requires calibration. Contact the
balancer manufacturer for calibration by their
repair representative.

4.

Static Balance Check
Attach a 5 g (0.18 ounce) weight to the outer rim.
Recheck the balancer. The balancer should detect
5 ± 2 g (0.18 ± 0.06 ounce) of imbalance 170 to 190
degrees away from the 5 g (0.18 ounce) weight.

｠

If the imbalance is within specification, the static
balance calibration is correct. Go to Step 5 to
check the dynamic balance.

｠

If the imbalance is out of specification, the
balancer requires calibration. Contact the

balancer manufacturer for calibration by their
repair representative.

5.

Dynamic Balance Check
Attach a 5 g (0.18 ounce) weight to the inner rim at
180 degrees opposite the 5 g (0.18 ounce) weight
that was added in Step 4. Recheck the balance. The
balancer should detect 5 ± 2 g (0.18 ± 0.06 ounce)
of imbalance 170 to 190 degrees away from both
the inner and outer 5 g (0.18 ounce) weights.

｠

If the imbalance is within specification, the
dynamic balance calibration is correct. The
balancer calibration checks are complete.

｠

If the imbalance is out of specification, the
balancer requires calibration. Contact the
balancer manufacturer for calibration by their
repair representative.
