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.

- Remove the wheel. Refer to → 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-.
