Removal and installation the subframe with attachments
It is necessary to take into account that when performing further work that requires loosening the threaded connection of the drive shaft/wheel hub, the vehicle must stand on its wheels. Unscrew the bolts securing the drive shaft to the wheel hub. 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 vehicle. Place the vehicle on a lift. Remove the wheels. Remove the coil springs. Remove the system resonator. exhaust. Disconnect the propeller shaft from the rear. main transmission. Secure the propeller shaft "3" with wire "1" to the body "2". Move the rear pipe of the propeller shaft towards the gearbox as far as possible.
On vehicles with a sport differential, unscrew the bolts "arrows" and remove bracket "1" from the rear final drive. Mark connector "2" for the oil pressure and temperature sensor on the clutch valves. Disconnect connector "2" of the oil pressure and temperature sensors from the clutch valves. Then disconnect connector "4" from the floor pump. drive "V415". Finally, disconnect the wiring harness "3" from the main transmission and subframe -pos. 5...7- and tie it up.
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".

Place it under the rear head. gear "1" with a suitable wooden block "2". Support the subframe from the front with a suitable wooden block "4" under the crossmember "3". Secure the subframe with the tension belt "T10038" on an engine and gearbox jack. Locate the tension belt "T10038" around the subframe below the drive shaft and route it behind the rear. head of the transmission. 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.
Valid for Allroad: Correctly install the spacer washers on the right/left side of the subframe silent blocks (with the ribbed side facing the body).
All
The subframe support holes must be located in the center of the mounting points on the body. Align the subframe so that dimension "a" for vehicles without stone protection is 19 mm, and dimension "b" for vehicles with stone protection is 14 mm. Install the coil springs only after the subframe bolts have been tightened to the specified torque.
Tighten the wheel. Adjusting the front and rear wheel alignment angle. the axle alignment is carried out on a wheel alignment stand recommended by VW/Audi.
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 silent blocks are installed: standard or hydraulic. Install 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.
