Rear suspension in unladen position
Special tools and workshop equipment required
t  Engine and gearbox jack -V.A.G 1383 A-
t  Tensioning strap -T10038-
t  Support -T10149-

All bolts on running gear components with bonded rubber bushes must always be tightened with suspension in the unladen position.
Bonded rubber bushes can only be turned to a limited extent.
Therefore, before tightening the bolts, suspension components with bonded rubber bushes must be brought into a position corresponding to the normal position of the unladen vehicle while driving (unladen position).
Otherwise, the bush would be subject to torsion loading and its service life would be shortened.
This position can be simulated on the lifting platform by raising the axle on one side with engine and gearbox jack -V.A.G 1383 A- and support -T10149-.
   
–  Use a measuring tape or similar to measure dimension -a- from wheel centre to lower edge of wheel housing.
This measurement must be taken with the suspension in the unladen position (vehicle unladen).
–  Make a note of the measured value. This will be needed when tightening the bolts and/or nuts on the suspension.
Before raising the axle on one side, the vehicle must be secured in position on the arms of the lifting platform with tensioning straps -T10038-.
If vehicle is not secured, there is a risk of it slipping off the lifting platform.
–  Turn wheel hub until one of the wheel bolt holes is at the top.
–  Use wheel bolt to attach support -T10149-.

–  Raise wheel bearing housing with engine and gearbox jack -V.A.G 1383 A- until distance -a- is obtained.
The bolts/nuts on the relevant suspension mountings must not be tightened until the distance -a- between the wheel centre and the lower edge of the wheel arch is the same as the distance measured before commencing work.
  WARNING
t  Do not lift or lower the vehicle while the engine/gearbox jack is under the vehicle.
t  Do not leave the engine/gearbox jack under the vehicle for longer than necessary.
–  Tighten relevant bolts/nuts.
–  Lower wheel bearing housing.
–  Pull out engine/gearbox jack from under vehicle.
–  Remove support -T10149-.
