Wheel Bearing In Curb Weight, Lifting Vehicles With Coil Spring
Wheel Bearing in Curb Weight, Lifting Vehicles with Coil Spring
Special tools, testers and auxiliary items required
• Engine-/Gearbox 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 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.
- Before starting work, take measurement - a -, for example with tape measure, from center of 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 individual suspension is raised on one side, vehicle must be secured to hoist lifting arms using (T10038).
If a vehicle is not secured, there is danger that the vehicle could slip off the lift!
- Remove wheel.
- Turn the wheel hub until one of the holes for the wheel bolts is on top.
- Install (T10149) with wheel bolt on wheel hub.
• 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.
- Lift the wheel bearing housing with the (V.A.G 1383 A) 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 the vehicle.
- Remove (T10149).
