Pressing Out the Bonded Rubber Mount

Before loosening subframe bolts, secure vehicle against tipping over (e.g. load luggage compartment with approximately 50 kg).

- Remove wheels.

- Mark position of crossmember on body using felt-tip pen.

- Remove left and right screws - arrows - from crossmember.

- Remove rear exhaust system.

- Disconnect and disengage all electrical wires from body to axle.

- Secure subframe. Refer to => [ Subframe, Securing ] Service and Repair.

• If the front bonded rubber bushing is replaced, an axle alignment must be performed.

• If the rear bonded rubber bushing is replaced, a road test must be performed. If steering wheel is crooked, vehicle must be aligned. Refer to => [ Wheel Alignment ] Wheel Alignment.

- Place (V.A.G 1383 A) with (V.A.G 1359/2) - 4 - under the subframe.

- Place a suitable wood block - 1 - under the subframe - 5 - and another one - 6 - under the rear final drive - 3 -.

- Secure the subframe on the (V.A.G 1383 A) with the (T10038) - 2 -.

- Remove two remaining attachments bolts for subframe.

- Lower subframe with a 2nd technician. The following must be observed when doing so:

• Lower it only as far as necessary.

• Note electrical wires and brake hoses

• Lower subframe evenly from body

- Lower subframe.

In order to press out the bonded rubber bushing, the cover on the mount's inner core must first be removed.

- Saw the bar - arrow - on the inner side of the cover - 1 - 6 times with the (V.A.G 1523 A). Saw the cuts - 2 - approximately 3 mm deep.

3 Underside of removed cover

- Pry off cover - 1 - with a screwdriver.

- If necessary, the support - arrow - with the small interior diameter must be removed from the (VAS 6178) and the (T10205/13) for that installed.

- Place the tools on the front bonded rubber bushing as shown in the illustration.

1. Thrust piece (T10301/5)

2. Support Ring (T10301/4). The chamfer on the exterior diameter must face toward the subframe.

3. Tube (T10301/3)

4. Hydraulic cylinder (VAS 6178)

5. Washer (T10205/4)

6. Nut (T10301/2)

7. Spindle (T10301/1)

• Secure (VAS 6178) while pressing out.

• Bonded rubber bushing loosens abruptly. There is the risk of injuries by tools and bonded rubber bushing coming off!

- Place (VAS 6208) underneath.

- Press out bonded rubber bushing and collect escaping oil.

Pressing In the Bonded Rubber Mount

Installation Location of Front Bonded Rubber Bushing

- Arrows - point in direction of travel.
