Chevrolet Cobalt Service & Repair Manual: Tire & Wheel Assembly Rotate & Balance
| A statically balanced wheel is
balanced in one plane, around centerline of wheel. This prevents simple
up and down movement relative to centerline of the wheel. A dynamically
balanced wheel is balanced on both sides of hub. This reduces the chance
of wobble off axis. Dynamic balancing is the preferred method for wheel
balancing. |
| A small amount of residual dynamic
imbalance is preferred over a similar amount of remaining static imbalance. |
| In general, it takes much more
residual dynamic imbalance to cause a vibration than the same amount of
static imbalance. |
| The larger the diameter used for
weight placement, the smaller the amount of correction weight is required. |
| The wider the distance between
the two weight placement locations, the smaller the amount of correction
weight is required. |
| If static balance is the only
option, always verify that the remaining dynamic residual imbalance is within
acceptable tolerance. |
| Refer to the operating instructions
from the wheel balancing equipment manufacture for proper operating procedures. |
| 1. |
Inspect tires for wear and proper inflation
pressure. |
| 2. |
Inspect radial and lateral tire runout
with dial indicator. Runout should be .06 inch or less when mounted
on vehicle and .05 or less off vehicle. |
| 3. |
Inspect and adjust tire balance using
a suitable wheel balancing machine. To achieve best balance on an
average sized tire and wheel assembly, residual static imbalance
should be less than .5 ounce and residual dynamic imbalance should
be less than .25 ounce per plane. |
| 4. |
Rotate tires as illustrated in Fig.
