WHEEL BALANCE ACCURACY

M1311001700656

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

.)

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.

Scalloped 
wear

Lack of rotation of tires or worn 
or out-of-alignment suspension

Rotate the tires, and 
check the front 
suspension 
alignment.

Refer to GROUP 
33, On-vehicle 
service − Front 

wheel alignment 
check and 
adjustment
