Wheel Bearing, Lifting to Curb Weight Position
Wheel Bearing, Lifting to Curb Weight Position
Special tools, testers and auxiliary items required
• Engine/Transmission Jack (V.A.G 1383 A)
• Tensioning Strap (T10038)
• Wheel Hub Support (T10149)
• All bolts at suspension parts with bonded rubber bushings must always be tightened to curb weight position (unloaded condition).
• Bonded rubber bushings can only be turned to a limited extent.
• Parts with bonded rubber bushings must therefore be brought into a position that corresponds to the position in driving mode before being tightened (curb weight position).
• Otherwise, the bonded rubber bushing will be stressed resulting in a shortened service life.
• By raising appropriate suspension using (V.A.G 1383 A) and (T10149) , this position can be simulated on the hoist.
- Before starting work, take measurement - a -, for example with a tape measure, from the center of the wheel to lower edge of wheelhouse.
• Measurement must be performed in curb weight position (unloaded condition).
- Note measured value. It will be required for tightening bolts/nuts.
Before appropriate suspension is raised, vehicle must be strapped to lift arms of hoist using (T10038).
If a vehicle is not secured, there is danger that the vehicle could slip off the lift!
- Turn the wheel hub until one of the holes for the wheel bolts is on top.
- Install (T10149) with wheel bolt on wheel hub.
- Using (V.A.G 1383 A) , lift wheel bearing housing until dimension - a - is reached.
• Tightening of the respective bolts/nuts must only occur if dimension - a -, measured before installation between wheel hub center and lower edge of wheel house, has been attained.
• Do not lift or lower vehicle with (V.A.G 1383 A) below vehicle.
• Do not leave (V.A.G 1383 A) below vehicle any longer than necessary.
- Tighten respective bolts/nuts.
- Lower wheel bearing housing.
- Move (V.A.G 1383 A) away from under the vehicle.
- Remove (T10149).
