Wheel Bearing, with Air Suspension, Lifting to Curb Weight Position
Special tools, testers and auxiliary items required
‹› Engine/transmission jack (V.A.G 1383 A)
‹› Torque Wrench (V.A.G 1783)
‹› Mount (T10149)
‹› Insertion tool 10 mm (V.A.G 1783/1)
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 engine/transmission jack (V.A.G 1383 A) and wheel
hub support (T10149).
