Volkswagen Golf Service & Repair Manual: Balancing wheel, balancing wheel with finish balancer

Before you start balancing the wheels, the following requirements must be met.
Tyre pressure must be OK.
Tread must not be worn on one side. Tread depth should be at least 4 mm.
The tyre must not show any signs of damage, for example cuts, piercing, foreign bodies, etc.
Wheel suspension and steering, including shock absorbers, must be in perfect condition.
Road test has been carried out → Chapter.
  Note
If bonded wheel trims are fitted, treat them with great care. The surface is susceptible to scratches.
If the wheel trim is damaged, renew wheel rim.
Use only the model-specific clamping plate -VAS 6652- and thrust pin -VAS 6652/1-.
  Note
Before working with a finish balancer, the mechanic needs to have been instructed by the manufacturer of the balancer.
To balance the wheels, set the wheels of the driven axle on the sensor platforms. On front-wheel drive models, front wheels must be set. On four-wheel drive models, all 4 wheels must be set.
If you determine a residual imbalance greater than 20 grams when balancing the wheels, you should rotate the mounting position of the wheel on the hub.
–  Mark the point at which the imbalance is indicated.
–  Then, unbolt the wheel and rotate its position on the hub so that the marking points downwards.
  Note
The hub must not rotate during this procedure.
–  First, hand-tighten the lowest wheel bolt to about 30 Nm.
–  Then, tighten the remaining wheel bolts diagonally to about 30 Nm. This process ensures that the wheel is centred properly on the hub.
–  Check whether the imbalance is less than 20 grams using the finish balancer.
  Note
The imbalance must be less than 20 grams before you change the balance weight.
–  Loosen the wheel bolts again if necessary.
–  Rotate wheel again by 1 or 2 wheel bolt holes in relation to wheel hub.
–  Tighten wheels using the method described above.
  Note
Do not try to reduce the imbalance using balancing weights unless the imbalance is less than 20 grams.
–  Balance wheels if imbalance is less than 5 grams.
–  Tighten wheel bolts to specified torque if you have not already done so.
Always tighten wheel bolts to specified tightening torque using a torque wrench!
