Wheel Bearing, Lifting To Curb Weight Position, 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 

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 : 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.

• The measurement must be taken in curb weight position. Refer to TEST REQUIREMENTS, AUDI Q7 - .

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

• Before the respective suspension is lifted up to the curb weight position, the vehicle must be tied down using the : T10038  on the : VAS6931  .

Front Axle 

-- Lightly secure both sides of the vehicle to the hoist lifting arms -arrow- using : T10038  on the upper rear control arm mounts -arrow A-.

Rear Axle 

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

Continuation for Both Axles 

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

-- Turn the wheel hub, until a wheel bolt hole is at the top.

-- Install the : T10149  with a wheel bolt -2- and inserted washer -1- on the wheel hub.

• 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.

-- Insert the : T10149  -1- in the : VAS6931  and lift the wheel bearing housing until the dimension -a- is reached.

-- Tighten the applicable bolts and nuts.

-- Lower the wheel bearing housing.

-- Move the : VAS6931  to the side

-- Remove the : T10149  .
