TROUBLESHOOTING
WHEEL AND TYRE31-4
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
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.

Pre-removal Operation
Raise the engine and transmission assembly until its weight
is not applied to the insulator, and support it securely.
