  Q: How to properly remove and install a Drive Shaft on Buick Enclave?

  A: The initial step requires marking the transfer case flange to the propeller shaft flange and the rear differential drive flange to minimize driveline system imbalance. This marking process should include painting or scribing these parts. Raise and support the vehicle. Record the positioning relationship between the front propeller shaft and the transfer case drive flange as well as the propeller shaft positioning with the rear differential yoke. First remove the mounting bolts and the propeller shaft bolts from the rear differential drive flange. Then support the propeller shaft at its rear differential position. Disassemble the propeller shaft bolts along with its associated washers from the system. A brass drift or punch should be placed on the propeller shaft where it meets between notches of the transfer case drive flange then a hammer can be used against the drift or punch to separate the propeller drive shaft from both transfer case and rear differential drive flange. Hold up the propeller shaft at the transfer case drive flange then loosen its center support mounting bolts. An assistant helps while you extract the propeller shaft both from the vehicle supports and vehicle itself. The installation process requires alignment of paint marks on the transfer case flange to propeller shaft flange and the rear differential drive flange for minimized driveline system imbalance. Apply threadlocker to the bolt threads after cleaning mounting bolts from the center bearing as well as front and rear propeller shaft drive flanges. First install several propeller shaft mounting bolts together with washers while support personnel maintain its position on both mounts. Drive the transfer case flange reference points to match those on the front propeller shaft before fastening the mounting bolt that centers the bearing. Placing the center support bearing onto the vehicle now allows you to install a few mounting bolts which will maintain the position of the propeller shaft. Locate the reference points of the rear propeller shaft based on the rear differential yoke. Secure the propeller shaft bolts with washers on the transfer case flange by tightening them to 34 Nm (25 lb ft). Position the center support bearing on the vehicle then install several mounting bolts onto the propeller shaft - rear differential yoke connection while tightening to 58 Nm (43 lb ft). Proceed by taking away the vehicle supports before lowering the vehicle to the floor.
