Raising rear axle to unladen position — VW

Raising rear axle to unladen position
Special tools and workshop equipment required
Engine and gearbox jack

All bolts on running gear components with bonded rubber bushes must be tightened only 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 axle on one side using the
engine and gearbox jack
V.A.G 1383 A
and
support

.
Measure distance
a
from centre of wheel to edge of wheel housing using, for example, a measuring tape
Fig.
.
Dimension
a
from lower edge of wheel housing to centre of wheel
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 axle on one side is raised, the vehicle must be strapped to the lifting platform arms using
tensioning strap
T10038
.
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.
Threaded connections may be tightened only when dimension
a
between the centre of wheel hub and lower edge of wheel housing, measured before starting work, has been attained.
Measuring dimension
a
Raise wheel bearing housing using engine and gearbox jack until dimension
a
is attained.
WARNING
Never raise or lower the vehicle while the engine and gearbox jack is positioned beneath the vehicle.
Do not leave the engine and gearbox jack under the vehicle for longer than necessary.
Tighten respective nuts and bolts.
Lower wheel bearing housing.
Pull engine and gearbox jack out from underneath vehicle.
