Driveshaft, servicing overview

Note. Observe general repair notes --> General Repair Notes . No repair work can be performed on the driveshaft - with the exception of removing and installing and adjustment work. Always store and transport driveshaft fully extended only. Driveshaft can be bent without force up to the center joint stop. 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. Driveshaft must also bend without force up to the center joint stop. Mark positions of all parts to each other before removing. Reinstall in identical position otherwise imbalance will be too high which could result in damage to the bearing or in vibration noises. Driveshaft bolts are loosened and tightened with the parking brake engaged. After disconnecting driveshaft from rear final drive, an installed balance washer (thick washer between backing plate and hex socket head bolt) may not be reinstalled. For complaints (noise, vibrations), check intermediate bearing for freedom from tension and radial run-out of driveshaft flange at rear final drive before replacing the driveshaft --> Measure radial play at flange/driveshaft and mark .
