DRIVESHAFT BOLTED ON TRANSMISSION-SIDE OVERVIEW

Note. Observe general repair notes, refer to REPAIR INFORMATION . The driveshafts 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 the 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 V10 T10172 and adapters T10172/5 to loosen or tighten the driveshaft bolts. After disconnecting the driveshaft from the 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.
