Wheel Bearing In Curb Weight Position, Lifting Vehicles With Coil Spring

WARNING: This page is about a different car, the 2022 Audi SQ7, 2022 Audi S7, and 2022 Audi Q7. However, it is still accessible from the selected car via links, so may be relevant.

TIP:

All bolts on chassis components with bonded rubber bushings must be tightened in curb weight position. Refer to 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 Engine and Gearbox Jack: VAS 6931 and Support Device: VAS 6931/1 , this position can be simulated on the hoist.

Special tools and workshop equipment required

Procedure

-- Determine the curb weight position. Refer to VEHICLES WITH COIL SPRINGS, CHECKING THE CURB WEIGHT POSITION FOR AXLE ALIGNMENT .

-- Note the measurement. This will be needed when tightening the bolts/nuts.

Before the respective suspension is lifted, the vehicle must be tied down to the hoist lifting arms with the Tensioning Strap: T10038 .

CAUTION:

Vehicle slipping from the hoist.

- Secure the vehicle on the hoist.

-- Lightly secure both sides of the vehicle to the hoist lifting arms -arrow B-, using the Tensioning Straps: T10038 -item 1- on the upper rear control arm mounts -arrow A-, for this, put a thin piece of rubber -2- in between to protect the paint.

CAUTION:

Vehicle slipping from the hoist.

- Secure the vehicle on the hoist.

-- Secure both sides of the vehicle to the hoist lifting arms -arrow B- to the strikers on the rear doors -arrow A- using Tensioning Straps: T10038 -item 1-.

Continuation for both axles

-- Remove the wheel. Refer to WHEELS AND TIRES .

-- Install the Support Device: VAS 6931/1 -item A- to the brake rotor -1- using two wheel bolts -2-.

-- Position the Engine and Gearbox Jack: VAS 6931 -item B- to the support bridge.

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.

-- Lift the wheel bearing housing, until the dimension -a- has been reached.

CAUTION:

There is a risk of an accident when lowering the vehicle when the engine and gearbox jack is underneath it.

- Never lower the vehicle when the engine and gearbox jack is underneath it.

- Never leave the engine and gearbox jack under the vehicle any longer than necessary.

-- Tighten the applicable bolts and nuts.

-- Lower the wheel bearing housing.

-- Move the Engine and Gearbox Jack: VAS 6931 to the side.
