Note.
- Necessary special devices, control and measuring instruments, as well as auxiliary means:
- Universal device (MRZ-419 (VW 771).
- Puller (MP3-419/37 (VW 771/37).
- Assembly tool (MRZ-434 (3066)).
- Drive sleeve (T10148)
- Receiving bath for collecting fuels and lubricants.
- Sealing grease (G 052 128 A1).
Removal
1. Remove the lower engine cover.
2. Turn the steering wheel all the way to the right.
3. Remove the drive shaft heat shield from the engine, if installed (arrows), as shown in the figure below.
Disconnect the drive shaft (1) from the flange shaft as shown in the figure below (for details, see the relevant section in Chapter Drive shafts).
5. Suspend the drive shaft as high as possible without damaging the protective paint coating of the drive shaft.
6. A special collecting pan should be placed under the engine and gearbox to collect fuel and lubricants.
7. If necessary, unscrew the turbocharger oil drain line from the engine (arrow), as shown in the figure below
8. Unscrew the bolt securing the shaft with the flange; for this purpose, screw two screws into the flange and hold the shaft with the flange using the assembly lever, as shown in the figure below.
9. Remove the shaft with flange, including the spring, from the gearbox housing.
10. Remove the seal together with the bushing. There is a flange in the inner diameter of the bushing.
Puller (VW 771/37 (MRZ-419/37)) should be installed immediately behind the flange in the bushing, as shown in the figure below.
During extraction, the puller must be pressed firmly (VW 771/37 (MP3-419/37)) to the sleeve.

Installation
1. Clean the sealing ring area in the gearbox.
2. Pressing in the seal with the sleeve.
- A - Screw the threaded rod from the assembly tool kit (MP3-434 (3066)) into the threaded part of the differential.
- B — Nut M12 with washer.
3. By turning the nut (B), press the seal with the sleeve through the pressure part (T10148) until it stops, as shown in the figure below.
4. Fill the space between the working edges halfway with sealing grease (G 052 128A1).
5. Install the shaft with flange into the gearbox housing.
6. The flange shaft should be secured with a conical head screw and tightened to the appropriate tightening torque.
7. If the turbocharger oil drain line was disconnected from the engine, it must be reinstalled (arrow). Tighten the union nut to the required tightening torque.
8. Connect the drive shaft (1) to the flange.
9. Install the drive shaft heat shield (arrows), if applicable. Install and tighten the shield mounting bolts to the specified torque.
10. Check the transmission oil level in the gearbox (see the relevant section in this chapter).
11. Install the lower engine cover.
