Wheel Bearing In Curb Weight, Lifting Vehicles With Coil Spring, Front Axle
Special tools and workshop equipment required
- Engine and Gearbox Jack:VAS6931 or Engine and Gearbox Jack:VAG1383A
- Tensioning Strap:T10038
- Engine/Gearbox Jack Adapter - Wheel Hub Support:T10149
All bolts on suspension components with bonded rubber bushings must always be tightened in curb weight position (unloaded condition).
Bonded rubber bushings have a limited range of rotation.
Axle components with bonded rubber bushings must be brought into the position they will be in when driving before they are tightened (curb weight position).
Otherwise, the bonded rubber bushing will have tension, which will reduce the service life.
By raising the corresponding suspension using the :VAS6931 or :VAG1383A and the :T10149 , this position can be simulated on the hoist.
Before the applicable suspension is raised, the vehicle must be secured to the hoist lifting arms using :T10038 .
There is a risk that the vehicle could fall off the hoist if it is not secured.
-- Turn the wheel hub until one of the holes for the wheel bolts is on top.
-- Install the :T10149 with a wheel bolt on the wheel hub.
The Bolts/Nuts Must Only be Tightened Once Dimension -a- Between the Center of the Wheel Hub and the Lower Edge of the Wheel Housing has Been Reached.
The dimension -a- is dependent on the height of the installed suspension:
| Chassis (1) | Standing Height -a- in mm | ||
|---|---|---|---|
| Raised (G02) | 477 ± 10 mm | ||
|
|||
-- Lift the wheel bearing housing using the :VAS6931 or :VAG1383A until dimension -a- is reached.
- Do not lift or lower the vehicle when the engine and gearbox jack is under the vehicle.
- Do not leave the :VAS6931 or :VAG1383A under the vehicle longer than necessary.
-- Tighten the applicable bolts and nuts.
-- Lower the wheel bearing housing.
-- Pull the :VAS6931 or :VAG1383A out from under the vehicle.
-- Remove the :T10149 .
