On-Vehicle Balancing

When needed, on-vehicle balancing will help correct vibrations due to brake drum, rotor, and wheel cover imbalance. When balancing on-vehicle, do not remove the balance weights from the off-vehicle dynamic balance. If more than one ounce of additional weight is required, it should be split between the inboard and outboard rim flanges. The driven tires and wheels should be spun using the engine. Limit speed as stated in the following caution.

CAUTION: 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.

CAUTION: Do not spin the drive wheels faster than 55 km/h (35 mph) 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.

To distinguish between standard rear axle and limited slip, raise rear of vehicle so both tires are clear of ground. With the transmission in "PARK" (in gear with a manual transmission) attempt to turn one wheel by hand. If the wheel can be turned easily, it is a standard rear axle: if the wheel cannot be turned easily, it is a limited slip rear axle. Also, check for limited slip (G80) on the Service Parts Identification label.
