WHEEL BALANCE ACCURACY
M1311001700258
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 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 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
