Driveshaft

Removing

Special tools, testers and auxiliary items required

• Assembly tool (3139)

• Pressing lever (80-200)

• M8 x 30 bolt (2x)

• Engine and transmission jack (VAG1383A) with universal transmission mounting (VAG1359/2)

- See notes, refer to => [ Driveshaft Assembly Overview ] Driveshaft Assembly Overview.

- Remove rear section of exhaust system as from clamp(s).

- Use pressing lever (80-200) to pry off rear attachments - A - of heat shield for driveshaft.





- Remove bolts - B - for center bearing.

• When removing the bolts support the driveshaft by hand. Do not bend driveshaft. Refer to => [ Driveshaft Assembly Overview ] Driveshaft Assembly Overview.

- Remove heat shield. Continue supporting driveshaft.

- Install bolts for center bearing again hand-tight.

- Remove heat shield for driveshaft off transmission - arrows -.





- Check for a factory marking (colored dot) on driveshaft and on driveshaft flange on final drive at the rear. If no colored dot is present, mark the position of the driveshaft flange - arrow A - relative to the rear final drive - arrow B - with a colored dot.





- Engage Assembly tool (3139) and tighten plastic nuts.





• Never install assembly appliance onto balance plates.

- Remove bolts - arrows - for the center bearing.





- Install M10 x 100 bolt - 3 - into rear final drive.





- To loosen bolts - 1 - of the driveshaft, counter hold with an assembly lever - 2 -.

- Remove bolts at the front Constant Velocity (CV) joint, detach the driveshaft and support it using engine and transmission jack (VAG1383A).

- Remove bolts at rear CV joint and detach driveshaft.

• Only transport and store driveshaft when extended.

Installing

Installation is carried out in reverse order. Note the following:

• To avoid imbalance, the flanges of the driveshaft - arrow A - and of the rear final drive - arrow B - must be installed so that the factory color markings or the markings made subsequently are in line.





• If a new driveshaft is installed and if the factory color marking on the flange of the rear final drive is no longer visible, the radial run out on the driveshaft flange must be measured. Refer to => [ Driveshaft Flange Measuring Radial Run Out and Marking ] Service and Repair, and the color marking on the driveshaft placed in line with the new marking on the flange.

• Replace gaskets on flange shafts (detach protective foil and stick gasket onto flange shaft).

• Remove the old and dry high temperature grease from the CV joints and the flanges for the driveshaft. Replace with the exact same quantity of new high temperature grease (G 000 633).

• Note the installation position of the driveshaft: The central CV joint is located behind the center bearing facing toward the rear final drive.

• After removing the driveshaft from the rear final drive, a thick washer that may be located between the shim and the bolt head must not be reinstalled.

• It is essential that the locking fluid remaining in the threads in the flange shafts on the transmission and rear final drive is cleaned out after removing the driveshaft. Otherwise there is a danger that the new bolts will seize when they are installed and then shear if they have to removed later.

• The threaded holes can be cleaned with a thread tap.

• Replace driveshaft bolts (self locking).

- Install driveshaft and bolts for CV joints.

- Install bolts - arrows - for center bearing hand tight.





- Install M10 x 100 bolt - 3 - into rear final drive.





- To tighten bolts - 1 - for the driveshaft, counter hold with an assembly lever - 2 -.

- Remove assembly device (3139)





- Remove bolts - arrows - for the center bearing. The driveshaft must be supported manually by a second mechanic.

• When removing the bolts support the driveshaft by hand. Refer to => [ Driveshaft Assembly Overview ] Driveshaft Assembly Overview.

- Install heat shield - 2 -. Continue supporting driveshaft.





- Install bolts - 4 - for center bearing several turns.

- Secure heat shield - 2 - on right and left at the center bearing - 3 - using bolts - 1 - (M8 x 30).

• When tightening the combination bolt - 4 - make sure that the center plug - arrow A - is located at the securing bore - arrow B -.

- Tighten bolts - 2 - for the center bearing.





- Install rear securing clips for the heat shield.

- Remove bolts - 1 -

- Install exhaust system and align stress-free.
