Replace the pendulum support bonded rubber bushing.

- Remove the front noise insulation. Refer to → Body Exterior; Rep. Gr.66; Overview - Noise Insulation.

- Remove the hex nut -1- from the right and left coupling rod -3-.

- Remove the coupling rod -3- from the stabilizer bar -2- on the left and right sides.

- Remove the stabilizer bolts -7- and -8-.

• Leave the stabilizer bar in the installed position on the vehicle.

- Remove the bolt -1-.

- Remove the bolts -2- and -3-.

- Remove the pendulum support.

Pressing out the bonded rubber bushing

- Install the Hydraulic Press - Bushing Tool Kit -VAS6779 -as shown in the illustration on the subframe.

- Position the Hydraulic Press - Bushing Tool Kit -Thrust Piece -VAS6779-1--1- with the flat side -arrow- on the bonded rubber bushing in the driving direction.

1 - Hydraulic Press - Bushing Tool Kit -Thrust Piece -VAS6779/1-

2 - Hydraulic Press - Bushing Tool Kit -Tube -VAS6779/4-, with the small outer diameter to the sub frame.

3 - Hydraulic Press - Bushing Tool Kit -Thrust Piece -VAS6779/5-

4 - Hydraulic Press -VAS6178- with Bearing Installer - Wheel Hub/Bearing Kit Pressure Head -T10205/13-

5 - Hydraulic Press - Bushing Tool Kit -Hexagon Nut -VAS6779/3-

6 - Hydraulic Press - Bushing Tool Kit -Threaded Rod -VAS6779/2-

- Press out both bonded rubber bushings until the upper bonded rubber busing -2- is visible through the opening for the pendulum support -arrow- in the subframe.

- Perform a visual inspection of the upper bonded rubber bushing -2- outer race.

• If the upper bonded rubber bushing -2- outer race is deformed, it must be destroyed through the opening for the pendulum support -arrow- in the subframe.

- Using a using a chisel or similar tool -1-, make a break in the upper bonded rubber bushing -2- outer race.

  Note

This work sequence is necessary to prevent tilting of the bonded rubber bushing outer race in the area of the pendulum support opening in the subframe.

- Completely press out both bonded rubber bushings at the same time.

Prepare the bonded rubber bushing before pressing in.

  Note

• There are two different versions of the pendulum support bonded rubber bushing: the T version -I- and the V version -II-.
• For the correct allocation. Refer to the Parts Catalog.

I - The corners on the inner core -1- face toward the opening for the pendulum support -arrow- (T version).

II - The corners on the inner core -2- face away from the opening for the pendulum support -arrow- (V version).

- Place the bonded rubber bushings -1- and -2- on top of each other so the openings -arrows- lay exactly over each other.

- Tighten the bonded rubber bushings -1- and -2- using the original bolt -3- hand tight.

- Place the bonded rubber busing -1- with the bolt head facing up in the larger diameter of the Hydraulic Press - Bushing Tool Kit - Funnel -VAS6779/6--2-.

- Align the bonded rubber busing -1- in the Hydraulic Press - Bushing Tool Kit - Funnel -VAS6779/6--2-. The bonded rubber bushing opening -arrows- must exactly lay in the recess on the Hydraulic Press - Bushing Tool Kit - Funnel -VAS6779/6--2-.

- Press the bonded rubber bushing -3- in the Hydraulic Press - Bushing Tool Kit - Funnel -VAS6779/6- as shown in the illustration until stop.

1 - Press Piece - Multiple Use -VW412-

2 - Hydraulic Press - Bushing Tool Kit -Thrust Piece -VAS6779/5-, the side with the letter "A" points up

3 - Bonded Rubber Bushing

4 - Funnel -VAS6779/6-

5 - Tube -VAS6779/4-

6 - Press Plate -VW401-

- Remove the bolt from the bonded rubber bushing.

- Place the Hydraulic Press - Bushing Tool Kit-Counter Hold -VAS6779/7--1- front left in the direction of the-arrow- on the subframe -2-.

- Insert the Insert -VAS6779/7-1A--1- in the pendulum support opening in the subframe.

- Attach the Insert -VAS6779/7-1A- with the bolt -arrow- on the Hydraulic Press - Bushing Tool Kit-Counter Hold -VAS6779/7--2-.

- Pay attention that the Insert -VAS6779/7-1A--1- is seated correctly in the subframe opening -arrow-.

Installing the bonded rubber bushing

- Install the Hydraulic Press - Bushing Tool Kit -Threaded Rod -VAS6779/2--7- in the Hydraulic Press - Bushing Tool Kit-Counter Hold -VAS6779/7--1-.

- Install the Hydraulic Press - Bushing Tool Kit -VAS6779- as shown in the illustration on the subframe.

1 - Hydraulic Press - Bushing Tool Kit-Counter Hold -VAS6779/7-

2 - Hydraulic Press - Bushing Tool Kit - Funnel -VAS6779/6-, -arrow marking- on the funnel must be opposite of both bolts -arrow A-.

3 - Hydraulic Press - Bushing Tool Kit - Thrust Piece -VAS6779/9-

4 - Hydraulic Press - Bushing Tool Kit -Incremental Ring -VAS6779/8-, the marking -IIII- on the Incremental Ring must point to the cam -arrow B- on the Hydraulic Press - Bushing Tool Kit -Thrust Piece -VAS6779/9-.
