Volkswagen Golf Service & Repair Manual: Remedies when vehicle pulls to one side
Test conditions before and during the road test: |
– |
Check all suspension components on the front and rear axles
for damage. |
– |
Check tyre pressure and correct if necessary. |
– |
Check the tyres for external damage. Punctures, cuts,
bubbles on the sidewalls, flat spots from braking and/or damage
to the tread. |
– |
Ask the customer if the tyre had been damaged by a nail or
similar object and was repaired by a tyre dealer. It may be
necessary to renew such tyres. |
– |
Check tyres for even wear and tread depth. |
– |
Are all tyres of the same type, manufacture and tread
pattern? |
– |
If the tyres are non-directional, ensure that all DOT
classifications on the tyre face outwards. The wheels and/or
tyres on the vehicle may have already been changed around at an
earlier date. |
– |
Is the make of tyre approved by the factory as original
equipment? |
– |
Perform the road test on a road which is level, straight and
ungrooved and does not drop off to one side. |
– |
Perform the road test with the customer under the conditions
specified above. Ask the customer to demonstrate the problem. |
Note
There must be no cross wind during the road test. |
If the complaint is justified, we recommend rotating the
wheels and tyres as described below. |
Before you begin, observe the following notes; otherwise
your efforts may not have the desired effect. |
Note
Mark the tyres before the first rotation, e.g. FR, FL, RR,
RL. |
After rotating wheels or reversing the tyre on its rim, you
must observe very carefully how the vehicle behaves during the
road test. Note how and what was changed. |
Assess the intensity of or a possible change in the tendency
to pull to one side. |
For this purpose, it is important that the road tests are
always performed by the same person on the same road. It is best
to drive the “test course” in both directions. |
Replacing a tyre with a new tyre does not guarantee that
pulling to one side will be eliminated. Therefore it is
recommended as a first step to carry out the strategic rotation
of the wheels as described below. |
If there are large differences in the tread depth of the
tyres on the front and rear axles, the tyres with the deeper
tread should always be mounted on the front axle. |

Perform a road test to determine if the vehicle pulls to one side and if
so, which side. |

If
the vehicle pulls to one side, interchange the front wheels. |

Perform a road test to determine if the vehicle pulls to one side and if
so, which side. |

If
the vehicle pulls to one side, interchange front and back wheels with

Conicity is caused by a slight offset of the tread and/or
the belt (amounting to a few tenths of a millimetre) relative to
the geometric centre of the tyre. Taper is ...
