Wheel Bearing In Curb Weight, Lifting Vehicles With Coil Spring

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2015 Audi S7, 2015 Audi RS 7, 2015 Audi A7 Quattro, 2014 Audi S7, and 2014 Audi RS 7. However, it is still accessible from the selected car via links, so may be relevant.

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 at suspension parts with bonded rubber bushings must always be tightened in curb weight position (unloaded condition).

Bonded rubber bushings have a limited range of motion.

Axle components with bonded rubber bushings must be brought into the position they will be in during driving before tightening (curb weight position).

Otherwise, the bonded rubber bushing will be stressed resulting in a shortened service life.

By raising appropriate suspension using Engine and Gearbox Jack VAS6931 and Engine/Gearbox Jack Adapter - Wheel Hub Support T10149, this position can be simulated on the hoist.

-- Measure dimension -a- from the center of the wheel to the lower edge of the wheel housing before beginning work, for example, using a tape measure.

The measurement must be taken with the vehicle in curb weight position (no load).

-- Note the measurement. It will be required for tightening bolts/nuts.

Front Axle

Before appropriate suspension is raised, vehicle must be strapped to lift arms of hoist using Tensioning Strap T10038.

Rear Axle

Before lifting the suspension, the vehicle must secured to the lifting arms on the hoist -arrow B- using the Tensioning Strap T10038 over the striker pin -arrow A-.

-- Place a piece of foam rubber -1- between the sill panel and the Tensioning Strap T10038 and then tension the Tensioning Strap T10038.

NOTE:

Be careful not to scratch the sill panel.

CAUTION:

The vehicle could fall off the hoist if it is not secured.

-- Remove the wheel, refer to WHEELS AND TIRES .

-- Turn the wheel hub until one of the holes for the wheel bolts is on top.

-- Install Engine/Gearbox Jack Adapter - Wheel Hub Support 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 using the Engine and Gearbox Jack VAS6931 until the dimension -a- is reached.

WARNING:

Do not lift or lower vehicle with the engine and gearbox jack still under the vehicle.
Do not leave the Engine and Gearbox Jack VAS6931 under the vehicle any longer than necessary.

-- Tighten the bolts and nuts.

-- Lower the wheel bearing housing.

-- Move Engine and Gearbox Jack VAS6931 away from under vehicle.

-- Remove the Engine/Gearbox Jack Adapter - Wheel Hub Support T10149.
