Replacing the front silent block or hydraulic silent block
Remove cover -1 - and -2-. Remove the fairings from the wheels.
Place powertrain lift with universal gearbox clamp -VAG 1359/2- under subframe -1-. Place a suitable block -2- under the subframe -1-.
Remove bolt -1- on left and right.
Screw the previously removed bolt -1- into the body, as shown in the figure, on the opposite side from the silent block to be replaced. Screw in the bolt -1- until the distance -a- is 4 cm.
Lower the subframe only 4 cm. Carefully unfasten the anti-rotation guard -1- with a suitable tool, e.g. with a screwdriver, in the area of the mounting protrusions in several stages, alternately on each side of the silent block.
For hydraulic silent block: Pull up the plastic insert -1- as shown in the figure.
All
Mark the installation position of the silent block or hydraulic silent block in relation to the subframe, for example using a felt-tip pen -arrows-.
If necessary, unscrew the support -arrow- from "small" internal diameter from the hydraulic cylinder -VAS 6178-, and instead screw in the support -T10205/13-.
Install the tools, as shown in the figure, on the front silent block.
- 1. Nut -T10263/5-
- 2. Stop -T40185/5-. The hole faces the silent block
- 3. Subframe
- 4. Support ring -T40185/6- The conical side must face upward and the bridges must fit into the holes in the silent block
- 5. Pipe -T40033/3-
- 6. Support ring -T10205/4-
- 7. Hydraulic cylinder -VAS 6178-
- 8. Nut -T10263/5-
- 9. Lead screw -T10263/4-. Leadscrew journal facing down
Attention! Hold hydraulic cylinder -VAS 6178- while pressing out. The silent block is disconnected "jerk". Falling tools and silent block can cause injury!
Installation position of the front silent block
Anti-rotation protection (aluminum plate) -1- is installed perpendicular to the direction of movement. -Arrow indicates the direction of movement of the vehicle.
Before installing the front silent block, carefully unfasten the anti-rotation protection -1- with a suitable tool, e.g. with a screwdriver, in the area of the fastening lugs -arrows- in several stages, alternately on each side of the silent block.
Install the tools, as shown in the figure, on the front silent block.
- 1. Nut -T10263/5-
- 2. Stop-T40185/4-
- 3. Subframe
- 4. Silent block or hydraulic silent block
- 5. Stop -T40185/3-
- 6. Support ring -T10205/4-
- 7. Hydraulic cylinder -VAS 6178-
- 8. Nut -T10263/5-
- 9. Lead screw -T10263/4-. The lead screw journal faces down.
Align the silent block according to the marked marks and press it into the correct position so that the collar is adjacent to the subframe bushing "no gap". To do this, if necessary, press out and press again using a cylinder. Make sure that the silent block is not distorted at the beginning of pressing, otherwise the outer ring may be damaged! The ends of the rubber protrusions on the silent block must coincide with the previously applied marks -arrows- on the subframe. After replacing the silent blocks, eliminate possible damage to the paintwork of the subframe using an anti-corrosion coating, primer and black paint. Install anti-rotation protection on the silent block. Install in reverse order.
Rear hydraulic silent block
Unscrew the nuts of both end muffler brackets until the threads begin. Position the powertrain lift with universal gearbox clamp -VAG 1359/2- under the subframe. Place a suitable block -2- under the subframe -1 -.
Unscrew the rear subframe bolts. Screw the spindle -3346/2- with mounting tool -3301- and nut -3346/3- into the body, as shown in the illustration, on the opposite side of the silent block to be replaced to a size of approx. 1.5 cm.
- 1. Mounting device -3301-
- 2. Nut -3346/3-
- 3. Lead screw -3346/2-
Screw the nut -3346/3- onto the spindle -3346/2- so that the dimension -a- is 4 cm. Lower the subframe only 4 cm. Carefully press the rotation lock -1 - using a suitable tool, e.g. a screwdriver, in the area protrusions in several stages alternately on each side of the hydraulic silent block.
Pull out the plastic insert -1- as shown in the illustration.
Mark the installation position of the hydraulic silent block in relation to the subframe, for example using a felt-tip pen -arrows-.
If necessary, unscrew the support -arrow- from "small" internal diameter from the hydraulic cylinder -VAS 6178-, and instead screw in the support -T10205/13-.

- 2. Stop -T40185/5-. The hole faces the silent block.
- 3. Subframe
- 4. Support ring -T40185/6- The conical side must face upwards and the transverse ribs must engage in the grooves of the silent block.
- 5. Pipe -T40033/3-
- 6. Support ring -T10205/4-
- 7. Hydraulic cylinder -VAS 6178-
- 8. Nut -T10263/5-
- 9. Lead screw -T10263/4-. The lead screw journal faces down.
Attention! Hold hydraulic cylinder -VAS 6178- while pressing out. The hydraulic silent block is disconnected "jerk".
Falling tools and hydraulic silent blocks can cause injury!
