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

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-, or example using a tape measure, from the center of the wheel to the lower edge of the fender/wheel housing.

The dimension -a- = the curb weight position depends on the suspension installed. Refer to VEHICLES WITH COIL SPRINGS, CHECKING THE CURB WEIGHT POSITION FOR AXLE ALIGNMENT .
The measurement must be taken in curb weight position.

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

CAUTION:

There is a risk of accident from the spring force of the coil springs if the vehicle slides off the hoist.

- Always secure the vehicle before raising the wheel bearing to the curb weight position.

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

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

CAUTION:

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

- Never lift or 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 :VAS6931 to the side

-- Remove the :T10149 .
