Removing
• A twin-pillar lifting platform should be used when working on the driveshaft.
• 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 when fully extended.
- Remove the crossmember for the underbody - arrows -, if equipped.
Risk of damaging decoupling elements.
• Do not bend decoupling elements in front exhaust pipe more than 10°.
- Separate the exhaust system at clamping sleeve - 1 -.
- Tie the front exhaust pipe to the underbody.
- Remove the exhaust system rear section.
- Loosen the driveshaft intermediate bearing bolts - arrows - approximately 2 turns.
- Support driveshaft in area of rear driveshaft tube using (V.A.G 1383 A).
A Wood support
- Secure the driveshaft against falling down using a strap from the (V.A.G 1359/2).
- Check whether there is a marking (colored dot) - arrows - on driveshaft and rear final drive driveshaft flange.
- If not, identify position of flexible disc and flange/driveshaft to rear final drive - arrows -.
- If equipped, remove the balance nut and balance disc - arrows -
• Do not reinstall the balance nut and balance disc - arrows - after the flexible disc has been removed.
- Counterhold the rear final drive with the (T10172) and (T10172/5) when loosening or tightening the driveshaft.
- Remove the rear driveshaft tube with the flexible disc and vibration damper from the final drive - arrows -.
- Carefully remove the rear driveshaft tube from the flange/driveshaft centering pins on final drive.
• Do not cant the driveshaft when removing. Pull off of the centering pin in a horizontal position. The sealing ring - arrow - in the centering bushing must not be damaged.
• The flexible disc and the vibration damper cannot be separated from each other.
- Identify location of rear flexible disc and flange from rear driveshaft to each other.
- Remove the flexible disc from the driveshaft tube - arrows -.
Installing
Installation is performed in the reverse order of removal while observing the following:
• Sealing rings - arrow - in driveshaft flanges must not be damaged when removing and installing.
• Replace the driveshaft if it is damaged.
• Do not tip rear driveshaft tube, push horizontally onto centering pins.
• Install all driveshaft parts marked in relation to each other in same position when reinstalling.
Location of flexible disc with vibration damper:
• The brace on the outer diameter - arrows - faces away from the driveshaft tube.
• Three projecting sleeves each on rear final drive flange/driveshaft and driveshaft flange engage in flexible disc mounting holes.
- Attach the flexible disc to the driveshaft tube - arrows -.
- Install driveshaft on final drive so that both markings - arrows - align.
- Attach the driveshaft with flexible disc to the rear final drive - arrows -.
Install the center bearing free of tension as follows:
• All driveshaft bolts are tightened.
- Align the intermediate bearing in its elongated holes so the driveshaft or bearing is not under stress.
- Tighten the combination bolt - 1 -. The combination bolts - 1 - must lie inside the four heat shield centering tabs - 2 -.
- Reconnect exhaust system making sure it is not under stress.
- Install the crossmember for the underbody - arrows -, if equipped.
