DRIVESHAFT BOLTED ON TRANSMISSION-SIDE ASSEMBLY OVERVIEW

Note. Observe general repair notes COMPONENT DESCRIPTION . The driveshaft cannot be repaired. They can only be removed, installed and adjusted. Always store and transport driveshaft fully extended only. The driveshaft can be bent at the center joint without using force. A hard bending to the stop may cause damage to the center joint or dust boot. If the driveshaft is only detached at the transmission or from rear final drive, it should be tied up or supported at the shaft end. If necessary, it is permitted to bend the driveshaft at the center joint without using force. Mark the position of all the parts before removing them. Install the parts in the same position, otherwise the imbalance can damage the bearing causing a humming noise. Use the counterhold tool Touareg V10T10172 and adapters T10172/5 to loosen or tighten the driveshaft bolts. After disconnecting driveshaft from rear final drive, an installed balance washer (thick washer between backing plate and internal multi-point bolt) may not be reinstalled. If there are complaints about noise or vibration, make sure there is no tension on the intermediate bearing before replacing the driveshaft.

DRIVESHAFT MOUNTED ON TRANSMISSION-SIDE ASSEMBLY OVERVIEW

Note. Observe general repair notes COMPONENT DESCRIPTION . The attached driveshaft can only be removed from the transmission if it is removed completely. The driveshaft cannot be repaired. They can only be removed, installed and adjusted. Always store and transport driveshaft fully extended only. The driveshaft can be bent at the center joint without using force. A hard bending to the stop may cause damage to the center joint or dust boot. If the driveshaft is only detached from rear final drive, it should be tied up or supported at the shaft end. If necessary, it is permitted to bend the driveshaft at the center joint without using force. Use the counterhold tool Touareg V10T10172 and adaptersT10172/5 to loosen or tighten the driveshaft bolts. Always hold the driveshaft horizontal when installing it or removing it from the transmission output shaft. Follow the tightening sequence for attaching the driveshaft bolts to the rear final drive DRIVESHAFT MOUNTED ON TRANSMISSION-SIDE ASSEMBLY OVERVIEW .

If there are complaints (noise, vibration), do the following before replacing the driveshaft

  1. Make sure the center bearing is free of tension.
  2. Remove the driveshaft bolts on the rear final drive. Tighten the driveshaft following the tightening sequence «DRIVESHAFT MOUNTED ON TRANSMISSION-SIDE ASSEMBLY OVERVIEW»(/audi/a4/b8-2007-2012/remont/axle-shafts/#rear-final-drive-0bd-avant__driveshaft-mounted-on-transmission-side-assembly-overview) .
