C 2500 Truck 2WD V8-5.7L VIN R (1997)
When needed, on-vehicle balancing will help correct vibrations due to brake drum, rotor, and wheel cover imbalance.
When balancing on-vehicle remove the balance weights from the off-vehicle dynamic balance. If more than 28 grams (one ounce) of additional weight
is required, it should be split between the inner and outer rim flange.
WARNING:
-
On vehicles equipped with limited slip rear axles, do not attempt to balance a tire on a drive wheel with the other drive wheel on the
ground. The vehicle may drive through this wheel and cause the vehicle to move unexpectedly, resulting in personal injury and
property damage.
-
Do not spin the drive wheels faster than 35 mph (55 km/h) as indicated by the speedometer. This limit is necessary because the
speedometer indicates only one-half of the actual wheel speed when one drive wheel is spinning and the other drive wheel is stopped.
Personal injury and damage may result from high speed spinning.
CAUTION: The driven tire and wheel assemblies should be spun using the engine. Limit speed as stated in the preceding Caution.
To distinguish between standard rear axle and a limited slip rear axle, check for Limited Slip Differential (G80) on the Service Parts Identification
label.
WHEEL BALANCE WEIGHTS
If more than 28 grams (1 ounce) are needed when static balancing, the balance weights should be split as equally as possible between the inboard and
outboard flanges.
Balancing of factory aluminum wheels requires the use of special polyester-coated clip-on type balance weights. These weights are designed to fit over
the thicker rim flange of the aluminum wheel. They also provide a much better appearance and will not discolor, corrode, or damage the wheel.
NOTE: When installing the polyester-coated weights, care must be used so the polyester coating does not crack. Use a teflon coated hammer.
ADHESIVE WHEEL BALANCE WEIGHT INSTALLATION
1. Wipe the wheel balance weight attachment area with a mixture of half isopropyl alcohol and half water. A clean cloth or paper towel must be used
for this operation.
2. Dry the attachment area with hot air. Surface of the wheel should be warm to the touch.
3. The adhesive backing on the wheel balance weights must be warmed to room temperature.
4. Remove the tape from back of the weights. Do not touch the adhesive surface.
5. Apply the wheel balance weight and press on it with hand pressure.
6. Secure the wheel balance weight with a 70 to 110 N (16 to 25 lb) force applied with a roller.
