TROUBLESHOOTING
WHEEL AND TYRE31-4
WHEEL BALANCE ACCURACYM1311001700247
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.
1. Wheels and tyres must be properly mounted on a
balancer in order to achieve correct balance.
Centring 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 tyres, 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
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 centre hole on the
hub side has a chamfered edge. Use a
back-mounting cone on your wheel balancer to
centre the wheel on the balancer shaft.
3. Install a wheel mounting cone. The appropriate
size cone for this vehicle is 67.0 mm.
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. Scalloped

or out-of-alignment suspensionRotate the tyres, and
check the front or

TROUBLESHOOTING
WHEEL AND TYRE31-5

1. After balancing the wheel, loosen the wing nut
and turn the wheel 180° 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° 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.

1. Mount an undamaged original-equipment alloy
rim and tyre assembly (wheel) onto your
off-the-car wheel balancer. Balance the wheel.
2. <>
Loosen the balancer wing nut, rotate the wheel a
half-turn (180°), and retighten the nut. Recheck
the balance.
•If the imbalance is 5g 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 5g, go to Step 3.
3. Loosen the balancer wing nut, rotate the wheel
1/4 turn (90°), and retighten the nut. Recheck the
wheel balance.
•If the imbalance is 5g or less, the wheel may not
be centred 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.•If the imbalance is more than 5g, the balancer
requires calibration. Contact the balancer
manufacturer for calibration by their repair
representative.
4. <>
Attach a 5g weight to the outer rim. Recheck the
balancer. The balancer should detect 5 ± 2g of
imbalance 170 to 190° away from the 5g 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. <>
Attach a 5g weight to the inner rim at 180°
opposite the 5g weight that was added in Step 4.
Recheck the balance. The balancer should detect
5 ± 2g of imbalance 170 to 190° away from both
the inner and outer 5g 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.
