Bonded rubber bushings can only be turned to a limited extent.
Before axle components with bonded rubber bushings are tightened, they have to be brought to a position which matches the position when the vehicle
is being operated (control position).
Otherwise the rubber mounting will be stressed, resulting in a reduced service life.
This position can be simulated on the lifting platform by raising the wheel bearing housing using (V.A.G 1383 A) and (T10149).
