Driveshaft

Driveshaft

• Perform work on the driveshaft on a twin post hoist if possible.

• Mark the position of all the parts to each other before removing them. Install in the same position otherwise the imbalance will be excessive and the bearings could get damaged causing rumbling noises.

• Do not kink the driveshaft, only store and move it when fully extended.

• Do not allow the driveshaft to hang down during removal. Always support it.

• Always remove or install the driveshaft horizontally with respect to the drive flange.

Special tools, testers and auxiliary items required

• Torque Wrench (5-50 Nm) (V.A.G 1332)

• Engine/Transmission Jack (V.A.G 1383 A)

• Counterhold Tool Touareg V10 (T10172)

Removing

- Remove the noise insulation.

- Remove the pendulum support to transmission bolts - 1 and 2 -.






- Press the engine/transmission forward and secure the position with a suitable piece of wood - A -.






- Support the front part of the exhaust system using the engine/transmission jack (V.A.G 1383 A).

- Disconnect the exhaust system at the clamping sleeve - arrows - and remove the rear exhaust system component.






- Remove the tunnel brace.

- Loosen the intermediate bearing to underbody bolts - arrows - 2 turns.






- Loosen but do not remove the front and rear flexible disc bolts.

- Counter hold the rear final drive to loosen and tighten the rear flexible disc bolts.






So that noises due to an imbalance do not occur later:

- If no marks - arrows - are present, mark the position of the rear flexible disc with respect to the rear final drive input flange.






- Also, mark the position of the front flexible disc with respect to the bevel box output flange.

- Unbolt the front flexible disc from the rear final drive input flange and lower it onto the engine/transmission jack (V.A.G 1383 A).

- When removing and installing the driveshaft, be careful not to damage the bushing - arrow -.






• Two technicians are needed to remove the driveshaft.

- Unbolt the front flexible disc from the bevel box output flange.


To prevent damaging the protective boot in the intermediate bearing, remove and install the driveshaft in its fully extended position; likewise, store it in this position.

- Unbolt the intermediate bearing and if possible, remove it to the rear in its fully extended length.

Installing

Installation is performed in the reverse order of removal while observing the following:

- Install all parts marked to each other in original positions.

- Tighten the front and rear flexible disc bolts. Tightening specifications. Refer to => [ Driveshaft ] Driveshaft.

- Tighten the pendulum support with new bolts - 1 and 2 -. Tightening specifications.






- Install the exhaust system.

- Install the noise insulation.

- Install the tunnel brace.
