Wheel Balance Inspection and Adjustment

Refer to Balancing Wheels Description Balancing Wheels Description.

Deposits of mud, etc. must be cleaned from inside of rim.

CAUTION:

Stones in the tread of a tire may cause injury when the wheel is spun for balancing.

Remove all stones from the tire tread before starting the balancing operation. This is also important to obtain a good balancing result.

Tire should be inspected for any damage, then balanced according to equipment manufacturer's recommendation.

Off-Vehicle Balancing

Most electronic off-vehicle balancers are more accurate than on-vehicle spin balancers. They are easy to use and give a dynamic (two plane) balance. Although they do not correct for drum or disc unbalance as does on-vehicle spin balancing, this is overcome by their accuracy, usually to within 1/8 ounce.

On-Vehicle Balancing

On-vehicle balancing methods vary with equipment and tool manufacturers. Be sure to follow each manufacturer's instructions during balancing operation.

WARNING:

If you spin a drive wheel so that the speedometer reads higher than 55 km/h (34 mile/h), there is a risk of tire separation and differential system failure, which can cause severe personal injury and/or extensive vehicle damage. This limit must be strictly observed because the speedometer indicates only one-half of the actual wheel speed when one drive wheel is spinning while the other drive wheel is stopped.

Be sure to limit the spinning speed of a drive wheel to an indicated speedometer reading of no higher than 55 km/h (34 mile/h).

NOTE:

If an on-vehicle balancing method is used for an ABS or ESP(R) equipped vehicle, with the ignition switch in the ON position, a DTC will be set for the ABS or ESP(R) system, even when there is no abnormal condition.

Do not turn the ignition switch to ON while a wheel is being spun.
