II. On-Car Finish Balance

On-car balancing is recommended only when off-car dynamic balancing and tire-wheel matching does not reduce vehicle vibration to an acceptable level.

Off-car dynamic balancing solves the vast majority of vibration problems; it balances tire and wheel assemblies statically and dynamically.

On-car balancing is recommended when other rotating vehicle parts are out of balance, such as brake rotors/drums, wheel covers, etc. On-car balancing normally corrects only static imbalances. Therefore, DO NOT REMOVE THE OFF-CAR BALANCE WEIGHTS. If removed before performing the on-car static balance, the lateral balance correction will be lost. In addition, always put half the on-car balance correction weights on each flange. It may be helpful to the customer if the on-car balance correction weights are marked with a paint stick; then, when the customer rotates that tire to another position on the vehicle, only the marked weights can be removed.

Hyundai recommends using Hofmann ELECTRONIC INFRARED MODEL TYPE IPK-2 finish balancer or equivalent. To properly balance the tire/wheel assembly on-car, one must follow the wheel balancer manufacturer's procedure. The following precautionary measures are necessary when spinning the DRIVE wheels by use of the vehicle engine.

1. Support both drive wheels on the pick-up supports supplied by the wheel balance manufacturer. Ensure that vibration from spin-up will not dislodge the vehicle.

2. Never spin-up the front wheels while they are in a hanging position as damage may occur to the front wheel drive mechanism.

3. Be sure that areas in front of and behind the tire/wheel assembly position are kept clear during spin-up.

4. Have another person start the engine and shift to automatic or manual high gear position.

5. Accelerate the engine slowly. Rapid acceleration could cause a wheel weight to fly off, or cause the vehicle to vibrate off the pick-up supports.

6. NEVER attempt to spin a DRIVE wheel assembly with a balancer spinner because lack of lubrication or cooling could damage the driveline, the transaxle, and the spinner.

7. Do not stop the wheels by using the vehicle's brakes while the vehicle is on the pick-up stands. Place the transaxle into neutral before decelerating.

8. Never exceed an indicated 80 mph when both wheels are spinning, or 40 mph if one of the two wheels is blocked (not rotating).
