Maximum bend angle: 10°. After installing the driveshaft approximately 50 mm onto the transmission output shaft, turn the driveshaft slightly to make sure the splines on the transmission output shaft mesh with the splines on the driveshaft. Push the driveshaft all the way onto the splines on the transmission output shaft. -- Install the bolts -arrows- just far enough so that the intermediate bearing can still be moved. Fig 11: Removing Mounting Bolts Courtesy of AUDI OF AMERICA, LLC -- Position the driveshaft on the rear final drive paying attention to the installed position: Fig 12: Identifying Mark Position Of Driveshaft Flange To Rear Final Drive Courtesy of AUDI OF AMERICA, LLC Die markings on the driveshaft -arrow A- and on the rear final drive -arrow B- must line up.
