- Place drip tray V.A.G 1306 underneath and drain transmission oil.
- Remove rear section of exhaust system (rearward of exhaust pipe clamp(s)):
- Remove heat shield above driveshaft.
- Remove heat shield next to rear final drive.





- Check whether there is a factory marking (paint spot) on driveshaft. If not, mark position of driveshaft flange -A- in relation to rear final drive (arrow -B-)with paint.
- Unscrew bolts from driveshaft flange.





- Secure driveshaft to parking brake cable bracket with wire.

Note: If it is not possible to push the driveshaft up and off the flange, lower the final drive before tying up the driveshaft. When lowering the final drive, prevent the driveshaft from dropping down, and do not bend the center joint further than the maximum angle permitted, Refer to Drive/Propeller Shaft, Service and Repair

- Support final drive with transmission jack V.A.G 1383 A.

- Unscrew 4 bolts for drive flange housing (see -1-, -2- and -3- in illustration).

Note: Fourth bolt not shown in illustration.

Installing
Installation is carried out in the reverse order; when doing this note the following:

Note:
^ After the driveshaft, it is important to clean any remaining locking compound out of the threads in the drive flanges on the transmission and rear final drive. If this is neglected, the new bolts can seize when they are screwed in and shear off later if they have to be removed.
^ The threaded holes can be cleaned with a thread tap.
^ Replace gasket between driveshaft and drive flange (pull off backing foil and stick gasket onto drive flange). Surface must be free of grease.
^ Replace driveshaft bolts (self-locking).

- If there is a factory marking on the driveshaft, measure the radial run-out at the flange for the driveshaft, Refer to Drive/Propeller Shaft, Service and Repair and align the paint marking on the driveshaft with new marking on the flange.
- Align exhaust system free of stress.
- Top up gear oil in rear final drive and check oil level.
