Lifting suspension to unladen position (vehicles with coil springs)
Special tools and workshop equipment required
t  Engine and gearbox jack -V.A.G 1383 A-
t  Tensioning strap -T10038-
t  Support -T10149-

  Note
All bolts on running gear components with bonded rubber bushes must always be tightened with the suspension in the unladen position (vehicle unladen).
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 appropriate part of the suspension with the engine and gearbox jack -V.A.G 1383 A- and support -T10149-.
   
–  Before commencing work, use 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 wheel unit, secure vehicle to arms of lifting platform using tensioning straps -T10038-.
If vehicle is not secured, there is a risk of it slipping off the lifting platform.
–  Remove wheel.
–  Turn wheel hub until one of the wheel bolt holes is at the top.
–  Attach support -T10149- to wheel hub using wheel bolt.
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.

–  Raise wheel bearing housing with engine and gearbox jack -V.A.G 1383 A- until distance -a- is obtained.
  WARNING
t  Do not raise or lower vehicle when engine and gearbox jack -V.A.G 1383 A- is under vehicle.
t  Do not leave engine and gearbox jack -V.A.G 1383 A- under vehicle for longer than necessary.
–  Tighten relevant bolts/nuts.
–  Lower wheel bearing housing.
–  Pull out engine and gearbox jack -V.A.G 1383 A- from underneath vehicle.
–  Remove support -T10149-.
