Volkswagen Golf Service & Repair Manual: Balancing wheel, balancing wheel on stationary wheel 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-. |
| Clamp wheel into wheel balancing machine |
| Dirt and rust in the area of the contact surfaces and centre
of the wheel distort the result. |
| – |
Clean contact surface, centring element and inside of wheel
using e.g. pneumatic brush grinding set -VAS 6446-
→ ServiceNet; Workshop Equipment, Catalogue before
clamping wheel on wheel balancing machine. |
Note
| It is essential that the correct tools for centring and
clamping the wheels are used on the wheel balancing system.
Before starting any work, find out about the respective centring
system for wheel balancing machines
→ ServiceNet; Workshop Equipment, Catalogue. |
|
|
|
| – |
Attach the wheel (together with tyre) to the wheel balancing
machine. |
Note
|
|
|
| To clamp the wheel in place, use centring system for wheel
balancing machines -VAS 5271-, for example. |
| This ensures that the wheel is 100% centred and that the
wheel will be clamped without damage! |
| The wheel cannot be perfectly centred on the wheel balancing
machine using conical clamping elements. |
| A deviation of 0.1 mm from the centre results in an
imbalance of 10 grams at the wheel/rim. |
| Procedure for balancing wheels and tyres |
| – |
Allow the wheel (together with tyre) to rotate on the wheel
balancing machine. |
| – |
Check that the indicator lines on the sidewalls of the tyre
near the wheel rim flange run evenly. |
| – |
Check tyre profile with wheel/tyre rotating. |
Note
| If one-sided wear, flat spots from braking or severely
washed out spots are apparent, balancing cannot achieve smooth
running. In this case, the tyre must be renewed. |
| – |
Check true running of wheel/tyre. If the wheel and tyre do
not run true although there are no flat spots, radial or lateral
runout may be the cause. |
| – |
Check the wheel for radial or lateral run-out
→ Chapter. |
| – |
If radial and lateral runout are within the specified
tolerance, balance the wheel and tyre. |
Note
| More than 60 grams of weight per tyre should not be used. |
| If more weight is required, you may be able to achieve
smoother running by "matching" the tyre and rim. Matching tyres
→ Chapter. |
| The wheel balancer display should indicate 0 gram. |
| As an alternative to match mounting, you could use the
vibration control system -VAS 6230 A-
→ Chapter. |
| – |
Bolt wheel onto vehicle. |
Caution
| In the case of ceramic brakes, it must be ensured
that the wheel does not fall onto the brake disc because
the latter will then be destroyed. When
removing/installing the wheel, fit the long assembly pin
into the upper position (12 o'clock position) instead of
the wheel bolt, and for additional support fit the short
assembly pin into the wheel bolt mountings. This allows
for sliding the wheel on the assembly aids when
removing/installing. |
|
| – |
Tighten lowest wheel bolt by hand to about 30 Nm. |
| – |
Tighten remaining wheel bolts diagonally to about 30 Nm.
This process centres the wheel on the hub. |
| – |
Lower vehicle onto its wheels. |
| – |
Use the torque wrench to firmly tighten the wheel bolts
diagonally to the prescribed torque. |
| If you detect vibration during the road test, it may be due
to wheel centring tolerances. |
| In unfavourable circumstances, the component tolerances of
wheels and hubs could cumulate. This too can lead to vibration.
This can be alleviated using a finish balancer.
