• 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:VAS6931  and Support Device:VAS6931/1  , this position can be simulated on the hoist.

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  .

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

-- Install the Support Device:VAS6931/1  -A- to the brake rotor -1- using two wheel bolts -2-.

-- Position the Engine and Gearbox Jack:VAS6931  -B- on the support device.

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

-- Tighten the applicable bolts and nuts.

-- Lower the wheel bearing housing.

-- Move the Engine and Gearbox Jack:VAS6931  to the side
