• Check the other bushings before replacing a faulty bonded rubber bushing.

• If cracks, oil leaks or other damage is visible, this bonded rubber busing must be replaced too.

• There are different versions, depending on the model, either a conventional bonded rubber bushing or a hydraulic one. Refer to => [ Front Bonded Rubber Bushing ] Subframe, Stabilizer Bar, Coupling Rod and Diagonal Brace Overview, AWD => [ Rear Bonded Rubber Bushing ] Subframe, Stabilizer Bar, Coupling Rod and Diagonal Brace Overview, AWD. Allocation, refer to the Electronic Parts Catalog (ETKA).

Applies to a Hydraulic Bonded Rubber Bushing

- Remove the plastic insert - 1 - upward as illustrated.

Applies to All

- Mark the installation position of the bonded rubber bushing or the hydraulic bonded rubber bushing on the subframe - arrows -.

The illustration shows a hydraulic bonded rubber bushing. On a conventional bonded rubber bushing, the recesses on the rubber shoulders are turned 90°.

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

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

1. Nut (T10263/5)

2. Thrust piece (T40185/5). The opening faces the rubber bonded bushing.

3. Subframe

4. Support Ring (T40185/6). The conical side must face upward and the ribs must fit into the openings in the rubber bonded bushing.

5. Tube (T40033/3)

6. Support ring (T10205/4)

7. (VAS 6178)

8. Nut (T10263/5)

9. Spindle (T10263/4). The spindle pins face downward.

• 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!

Installation Location of Front Bonded Rubber Bushing

7. (VAS 6178)

8. Nut (T10263/5)

9. Spindle (T10263/4). The spindle pins face downward.

- Align the bonded rubber bushing with the markings made previously and push it in until the collar comes in contact with the bushing in the subframe without any gaps. If necessary, tension and press over cylinder several times. While pulling in, make sure the bonded rubber bushing does not cant, otherwise outer ring could be damaged.

- The ends of the rubber bead on the bonded rubber bushing must align with the markings - arrows - on the subframe.
