Wheel alignment

WARNING!

Do not re-use any fasteners that are worn or
deformed in normal use.
Some fasteners are designed to be used only
once, and are unreliable and may fail if used
a second time. This includes, but is not
limited to, nuts, bolts, washers, circlips and
cotter pins. Always follow the
recommendations in this manual-replace
these fasteners with new parts where
indicated, and any other time it is deemed
necessary by inspection.
The wheel alignment should be measured using
VW/Audi approved wheel alignment equipment.
Wheel alignment checks must always include
both the front and the rear axles. Otherwise the
proper running characteristics of the vehicle
cannot be ensured.

Notes:
The wheel alignment should not be checked
before the vehicle has completed 1000-2000
km (600-1200 miles) so that the coil springs
have time to settle.

Rear axle toe (front-wheel-drive
vehicles), centering

Individual toe settings on the rear axle cannot be
adjusted.
By moving the rear axle within the elongated
holes it is possible to center the individual toe
settings.

- Loosen securing bolts on mounting brackets.

- Center individual toe settings by moving axle
beam within elongated holes at mounting
brackets.
If the overall toe setting is outside the allowable
tolerance, or if it is not possible to center the
individual settings, the axle beam must be
checked for damage and replaced if necessary.
The body alignment must also be
checked/measured in the area of the rear axle
mounting points and serviced as necessary.
