Wheel alignment

General

The vehicle alignment should be measured using VW
approved wheel alignment equipment!

We recommend that the front and rear axles are measured
when performing alignment measurements.

Otherwise correct vehicle performance is not guaranteed
and an off center steering wheel may exist.

Note:

n

Perform vehicle alignment only after 1000-2000 km
(600-1200 miles) to allow suspension time to settled.

n

The individual specifications should be followed as
exactly as possible when making adjustments.

If the installation position of rear axle and the direction of
travel of vehicle is not taken into account an off-center
steering wheel may occur.

Steering wheel and steering column are marked.

These positions must not be changed!

A - Marked line on steering wheel

B - Punch mark on steering column

Otherwise the center position of the steering rack cannot be
guaranteed.

Vehicles with Electronic Stabilization Program (ESP)

If the steering wheel is off-center, the basic setting for
the steering angle sensor must be checked.

⇒ Perform

After wheel alignment and following test drive the steering
column must be marked.

Wheel alignment

(alignment equipment) are not touching the end stop
when checking wheel alignment.

Caution!

The test equipment must be properly adjusted and
attached to the vehicle; observe manufacturers
operating instructions.

Adhere to manufacturer of your vehicle alignment
equipment for training as required.

Vehicle alignment platforms and vehicle alignment
units/vehicle alignment computers can lose their calibration
over a period of time.

Vehicle alignment platforms and vehicle alignment
units/vehicle alignment computers should be checked
and if necessary adjusted within the framework of an
inspection/maintenance at least once a year!

- Treat these highly sensitive units carefully and
conscientiously!

Measurement preparations

Special tools, testers and auxiliary items required

n

Brake pedal depressor V.A.G1869/2

The lateral run-out of the wheel must be compensated
for. Otherwise the result of the measurement will be
incorrect.

If the lateral run-out compensation is not performed it
is not possible to adjust the toe correctly!

When doing this observe the information from the
manufacturer of the wheel alignment unit.

- Carry out wheel run-out compensation.

- Lower vehicle and bounce springs.

- Install brake pedal loading device V.A.G1869/2 .

- Actuate brake pedal with brake pedal loading device.

Vehicle trim height "Zero position"

Applies in principle!

If a value lies outside the tolerance, the vehicles trim height
must be checked first.
