Before beginning balancing, the following requirements must be fulfilled.

The tire pressure must be OK.

The tire profile must not be worn on one side. The tire profile must be at least 4 mm.

The tires must not have any damage such as cuts, holes, foreign bodies, etc.

The suspension and steering, including the shock absorber, must be in perfect condition.

Test drive performed. Refer to → Chapter „Vibration, Road Test, Performing Before Balancing“.

Note

If equipped handle the glued-on wheel trim carefully. Surface slightly scratched.

Replace the damaged rim wheel trim.

Use only the Model-Specific Clamping Plate -VAS6652- and the Thrust Pin -VAS6652/1-.

Note

Working with a Finish Balancer requires instruction from the manufacturer of the balancer.

When balancing, place the wheels of the driven axle on the turntable sensors. On a FWD vehicle, the front wheels must be on the sensors. On AWD vehicles, all 4 wheels must be on the sensors.

If it is determined when balancing on the vehicle the remaining imbalance is more than 20 grams, the wheel should be rotated on the wheel hub.

–	Mark the point at which the imbalance is indicated.

–	Afterwards, unbolt the wheel and rotate its position on the wheel hub so that the marking points downward.

Note

The wheel hub must not turn during this procedure.

–	First, tighten the lowest wheel bolt hand-tight to approximately 30 Nm.

–	Tighten the remaining wheel bolts diagonally to approximately 30 Nm. This process centers the wheel properly on the wheel hub.

–	- Check again whether the imbalance is less than 20 grams using the finish balancer.

Note

The imbalance should not be smaller than 20 grams under any circumstances before changing balance weight.

–	Loosen the wheel bolts again, if necessary.

–	Rotate the wheel relative to the wheel hub once more by one or two wheel bolt holes.

–	Tighten the wheels according to the method described above.

Note

Only if the imbalance is less than 20 grams should the imbalance be reduced by changing the balance weight.

–	Balance the wheels until the imbalance is below 5 grams.

–	Tighten the wheel bolts to the specified tightening specification if you have not already done so.

Always Tighten the Wheel Bolt to the Tightening Specification and Using the Torque Wrench.
