Installing driveshaft - Audi A4 and Cabriolet, Audi A6

Installation is in reverse order of removal. Note the following:

• Remove old and dry high-temperature grease from CV joints and flanges for driveshaft. Fill the exact same amount of new grease G 000 633.
• Always remove any remaining locking fluid from thread bores in drive flanges for transmission driveshaft and for rear final drive. Cleaning can be performed with a tap. Otherwise, the securing bolts can shear while installing.
• After disconnecting driveshaft from rear final drive, an additional balance washer (thick washer) that may be located between shim and a mounting bolt may not be reinstalled.
• Always replace (self-locking) securing bolts for driveshaft.

• Note installation position of driveshaft: Center CV joint is located behind intermediate bearing in direction facing the rear final drive.
