WHEEL BALANCE ACCURACY
M1311001700247
PURPOSE
This section contains tips and procedures for achiev-
ing accurate wheel balance. Steering wheel vibration
and/or body shake can result if any of these proce-
dures 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 instruc-
tion manual should include calibration procedures. If
the calibration procedures specifically for your bal-
ancer are missing, use the generic steps in this sec-
tion for zero calibration, static balance, and dynamic
balance checks. The wheel balancer calibration
checks are also described in the flowchart. (Refer to
).
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 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.

<Confirming Proper Balance>
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.
<Wheel Balancer Calibration Checks>
1. Mount an undamaged original-equipment alloy
rim and tyre 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
° ), and retighten the nut. Recheck
the balance.
• If the imbalance is 5 g 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, 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 5 g 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 5 g, the balancer
requires calibration. Contact the balancer manu-
facturer for calibration by their repair representa-
tive.
4. <<Static Balance Check>>
Attach a 5 g weight to the outer rim. Recheck the
balancer. The balancer should detect 5
± 2 g of
imbalance 170 to 190
° away from the 5 g 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 bal-
ancer requires calibration. Contact the balancer
manufacturer for calibration by their repair repre-
sentative.
5. <<Dynamic Balance Check>>
Attach a 5 g weight to the inner rim at 180
°
opposite the 5 g weight that was added in Step 4.
Recheck the balance. The balancer should detect
5
± 2 g of imbalance 170 to 190° away from both
the inner and outer 5 g weights.
• If the imbalance is within specification, the
dynamic balance calibration is correct. The bal-
ancer calibration checks are complete.
• If the imbalance is out of specification, the bal-
ancer requires calibration. Contact the balancer
manufacturer for calibration by their repair repre-
sentative.
