• Torque Wrench 1332 40-200Nm -VAG1332-
• Hydraulic Press -VAS6178-
• Pneumatic/Hydraulic Foot Pump -VAS6179-
• Rubber Bushing Assembly Device Kit -VAS6779A-
• Press Plate -VW401-
• Press Piece - Multiple Use -VW412-

Replace the Bonded Rubber Bushing for the Pendulum Support.

• Remove the front 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 bar 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 Rubber Bushing Assembly Device Kit -VAS6779A- on the subframe as shown.
• Position the Rubber Bushing Assembly Device Kit - Thrust Piece -VAS6779/1--1- with the flat side -arrow- on the bonded rubber bushing in the direction of travel.

• Press out both bonded rubber bushings until the upper bonded rubber bushing -2- is visible in the pendulum support opening -arrow- in the subframe.
• Perform a visual inspection of the upper bonded rubber bushing outer race -2-.

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

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

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.

Preparing Bonded Rubber Bushings 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-.
• Refer to the Parts Catalog for the allocation.

1. 1
   The corners on the inner core -1- face toward the opening for the pendulum support -arrow- (T version).
2. 2
   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 directly over each other.
• Tighten the bonded rubber bushings -1 and 2- using the original bolt -3- hand tight.

• Place the bonded rubber bushing -1- with the bolt head facing up in the larger diameter of the Rubber Bushing Assembly Device Kit - Funnel -VAS6779/6--2-.
• Align the bonded rubber bushing -1- in the Rubber Bushing Assembly Device Kit - Funnel -VAS6779/6--2-. The opening in the bonded rubber bushing must directly face the recess -arrows- in the Rubber Bushing Assembly Device Kit - Funnel -VAS6779/6--2-.

• Press the bonded rubber bushing -3- in the Rubber Bushing Assembly Device Kit - Funnel -VAS6779/6- until it stops as shown in the illustration.

• 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 -arrow- on the subframe -2-.

• Insert the Rubber Bushing Assembly Device Kit - Insert -VAS6779/7-1A--1- in the pendulum support opening in the subframe.
• Attach the Rubber Bushing Assembly Device Kit - Insert -VAS6779/7-1A- with the bolt -arrow- on the Hydraulic Press - Bushing Tool Kit-Counter Hold -VAS6779/7--2-.
• Pay attention that the Rubber Bushing Assembly Device Kit - Counterhold -VAS6779/7-1A--1- is seated correctly in the subframe opening -arrow-.

Installing the Bonded Rubber Bushings

• Install the Rubber Bushing Assembly Device Kit -Threaded Rod -VAS6779/2--7- in the Rubber Bushing Assembly Device Kit - Counterhold -VAS6779/7--1-.
• Install the Rubber Bushing Assembly Device Kit -VAS6779- as shown in the illustration on the subframe.
