Removal and installation the subframe with attachments
Before starting work, measure the distance "a" from the center of the wheel to the lower edge of the wheel arch while the wheels are still on the car.
Place the car on a lift. Remove the wheels. Remove the coil springs. Remove the system resonator. exhaust. Unscrew bolt "2" on the right and left and remove bracket "1" with wires.
Unlock and disconnect plug connection "1" of the rear left speed sensor "G46" and the rear right speed sensor "G44". Unlock and remove connectors "3" of the right and left electronic mechanical parking brake. Disconnect plug "5" from the rear left door sensor. clearance "G76" and, if available, from the right rear. door sensor. clearance "G77" and remove it. Disconnect wiring harness "4" on the left and, if present, on the right. On vehicles with an electrical system. adjuster, damping, disconnect the connector on the bumper and release the wiring harness.
Unlock the locking tabs "1" and remove the stone protection "2".
Unscrew bolt "1" and remove washer "2".
Disconnect bolt connection "1". Remove the brake caliper. Guide the caliper past the suspension elements and secure it to the body so that the weight of the caliper does not press on the brake. hoses or lines, which may damage them. Screw the upper wishbone to the hub assembly "1" by hand.
Remove cover "1" and "2".
Remove stone guards "1" and "2" if present.
Place a tilting device with a universal mount for the "VAG1359/2" gearbox under the subframe and secure it with the "T10038" tensioning belt. Place a suitable wooden block "2" under the rear of the "1" subframe. Place a suitable wooden block "3" under the rear of the "4" subframe. Route the "T10038" tensioning belt between the subframe and the fuel tank. Route the tension belt "T10038" under the universal transmission mount "VAG 1359/2" and tighten it.
Unscrew bolts "1" and "2" on the left and right. Remove supports "3" from the left and right.
Loosen the "arrow" bolts. Carefully lower the subframe with the attached parts. At the same time, pay attention to the brakes. calipers and brakes. highways.
Installation
Installation in reverse order. Silent blocks have a limited torsional working range. Therefore, wheel suspension bolt connections should only be tightened when the vehicle is in the unloaded or standard suspension position. Raise the wheel support with the suspension in a static position on a vehicle with coil springs. The subframe support holes must be located in the center of the mounting points on the body. On all-wheel drive vehicles with a subframe, align the subframe so that dimension "a" for vehicles without a skid plate is 19 mm, and dimension "b" for vehicles with a skid plate is 14 mm. Install the coil springs only after the subframe bolts have been tightened to the specified torque.
Replacement of silent block and hydras, subframe silent block
If a silent block is damaged, the silent block on the opposite side should also be replaced. Before replacing a faulty silent block, inspect the remaining silent blocks. If cracks, oil stains, or other damage are present, these silent blocks should also be replaced. Depending on the model, different versions of the site-tent block are installed: standard or hydraulic. Place the car on a lift. Remove the wheels. Remove the coil springs. To replace the silent block, lower the subframe in the front or rear. areas. There is no need to remove the subframe. Lower the subframe alternately in the front or rear. area. This will avoid adjusting the wheel alignment angles. The subframe should not be lowered more than 4 cm. Before removing the silent blocks, mark their installation position relative to the subframe.
Replacing the front silent block or hydraulic silent block
Remove cover "1" and "2".
Install a powertrain lift with a universal gearbox grip "VAG 1359/2" under the subframe "1". Place a suitable block "2" under the subframe "1".
Unscrew bolts "1" and "2" on the left and right. Remove supports "3" from the left and right.
Screw the lead screw "3346/2" into the body with the mounting device "3301" and the nut "3346/3", as shown in the picture, on the opposite side of the silent block being replaced to a size of approx. 1.5 cm.

Installation
Installation in reverse order. Silent blocks have a limited torsional working range. Therefore, wheel suspension bolt connections should only be tightened when the vehicle is in the unloaded or standard suspension position. Raise the wheel support with the suspension in a static position on a vehicle with coil springs. Install the stabilizer and tighten the bolts. First, tighten bolts "2" on the left and right. Then tighten bolts "2" evenly on the left and right. Insert bolt "1" with washer "2" and tighten nut "3" on the left and right. Tighten bolt "4" on the left and right. Tighten the wheel.
