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.
