Audi A4: Wheel Bearing in Curb Weight Position, Lifting Vehicles with Coil Spring
Special tools and workshop equipment required
- Engine and Gearbox Jack -VAS6931-
- Tensioning Strap -T10038-
- Engine/Gearbox Jack Adapter - Wheel Hub Support -T10149-
Note
All bolts on chassis components with bonded rubber bushings
must be tightened in curb weight position. Refer to
→ Chapter "Vehicles with Coil Springs, Checking the Curb Weight
Position for Axle Alignment".
- 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-
and -T10149-, this position can be simulated on the hoist.
Procedure
- Before starting the procedure, determine the measurement
-a-, for example using a tape
measure, from the center of the wheel to the lower edge of the
fender/wheel housing.
Note
The measurement must be taken in curb weight position.
- Note the measurement. This will be needed when tightening
the bolts/nuts.

→ Chapter "Wheels and Tires".
- Turn the wheel hub, until a wheel bolt hole is at the top.
- Install the -T10149- with a wheel bolt
-2- on the wheel hub.

Note
Ignore item -1-.
Note
Tightening of the applicable bolts/nuts must only occur if
the dimension between the center of the wheel hub and the lower
edge of the fender/wheel housing that was measured before
starting the procedure has been attained.
WARNING
Risk of accident!
A vehicle that is not secured can slide off the
hoist.
- Insert the -T10149- in the -VAS6931- and lift the wheel
bearing housing slightly.
- Before the respective suspension is lifted up to the curb
weight position, the vehicle must be tied down using the
-T10038- on the -VAS6931-.
- Lift the wheel bearing housing, until the dimension
-a- has been reached.
WARNING
Risk of accident!
- Do not lift or lower the vehicle when the -VAS6931-
is under the vehicle.
- Do not leave the -VAS6931- under the vehicle any
longer than necessary.
- Tighten the applicable bolts and nuts.
- Lower the wheel bearing housing.
- Move the -VAS6931- to the side
- Remove the -T10149-.
