Procedures
Wheel Bearing, Bringing to Curb Weight Position
Special tools, testers and auxiliary items required
• Engine/transmission jack (V.A.G 1383 A)
• Tensioning strap (T10038)
• Mount (T10149)
• All bolts at suspension parts with bonded rubber bushings must always be tightened in 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.
- For example, measure dimension - a - from center of wheel to lower edge of wheel housing using a tape measure before starting work.
• 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 wheel hub far enough until one of the holes for wheel bolts is on top.
- Install (T10149) with wheel bolt.
Before starting work, stabilizer bars must be coupled in vehicles with separable stabilizer bars. Otherwise, there is the danger of injury caused by unintentional coupling.
Tightening of the respective bolts/nuts must then only occur after dimension - a -, which was measured before installation between the wheel hub center and the lower edge of wheel housing, has been attained.
- Using (V.A.G 1383 A), lift wheel bearing housing until dimension - a - is reached.
• Do not lift or lower vehicle when the (V.A.G 1383 A) stands below the vehicle.
• Do not leave (V.A.G 1383 A) below vehicle any longer than necessary.
- Tighten respective bolts/nuts.
- Lower wheel bearing housing.
- Remove (V.A.G 1383 A) under vehicle.
- Remove (T10149).
