Rear axle in unladen position (four-wheel drive)
   
Rear axle in unladen position (four-wheel drive)
Special tools and workshop equipment required
t  Engine/gearbox jack -V.A.G 1383 A-
t  Support tool -T10038-
t  Mounting -T10149-

  Note
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 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.
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 -T10149-.
   
Before the axle on one side is raised, both sides of the vehicle must be strapped to the lifting platform arms with tensioning straps -T10038-.
  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.
–  Use wheel bolt to attach support -T10149-.
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.
  N42-10224
