All bolts on running gear components with bonded rubber bushes may be tightened only when the component is in the unladen position (normal position).
Bonded rubber bushes can be twisted only to a limited extent.
Axle components with bonded rubber bushes must therefore be brought to a position equivalent to the unladen (normal) position before being tightened.
Otherwise, the bonded rubber bush would be subject to torsion loading, shortening its service life.
To simulate this position on the lifting platform, raise the respective wheel suspension with the
engine and gearbox jack
V.A.G 1383 A
and

.
Before starting work, measure distance
a
from centre of wheel to edge of wheel housing using, for example, a measuring tape
.
The measurement must be performed in the unladen position (normal position).
Note measured value. This will be needed when the bolts and nuts are tightened.
Before the respective wheel suspension is raised, the vehicle must be strapped to the lifting platform arms using
tensioning straps

.
WARNING
If the vehicle is not strapped down, there is a danger that the vehicle will slip off the lifting platform!
Turn wheel hub until one of the wheel bolt holes is at the top.
Attach
support

with a wheel bolt.
WARNING
In vehicles with disengageable anti-roll bars, the anti-roll bars must be engaged before beginning work. Disengaged anti-roll bars otherwise pose a risk of injury due to unintentional engagement.
Respective nuts and bolts may be tightened only when dimension
a
between the centre of wheel hub and edge of wheel housing, measured before starting work, has been attained

.
Raise wheel bearing housing using
engine and gearbox jack
until dimension
a
is attained.
WARNING
Do not lift or lower vehicle while
engine and gearbox jack
is under vehicle.
Do not leave
engine and gearbox jack
under vehicle longer than necessary.
Tighten respective nuts and bolts.
Lower wheel bearing housing.
Pull
