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

  A:

  It is vital to create paint markings or scribe lines between the transfer case flange and propeller shaft flange as well as the rear differential drive flange to minimize any imbalance in the driveline system. Ascend the vehicle before making marks that show how the front propeller shaft joins with the transfer case drive flange and the rear propeller shaft connects to the rear differential yoke. Dangerous work requires removing the bolts around the rear differential drive flange together with the propeller shaft bolts before supporting the propeller shaft through the rear differential. First remove the propeller shaft bolts along with each washer round the propeller shaft. The use of a brass drift or punch positioned at the propeller shaft notches in the transfer case drive flange will allow you to remove both the propeller drive shaft from the transfer case drive flange and then from the rear differential drive flange by carefully striking with a hammer. Support the propeller shaft where it connects to the transfer case drive flange then uninstall the bolts that mount the center support. Remove the support-mounted propeller shaft by working jointly with an assistant both on the vehicle and support structures. To minimize driveline system imbalance install the components by lining up the paint or scribe reference marks between the transfer case flange and the propeller shaft flange together with the rear differential drive flange. It is necessary to clean all bolts used for center bearing mounting as well as front and rear propeller shaft drive flanges. The propeller shaft should be positioned with helping hands on the supports before installing several mounting bolts together with washers to secure its position. Centre the reference marks of the front propeller shaft with the transfer case flange while installing the mounting bolt to maintain the center bearing position. Install temporary mounting bolts to the vehicle-based center support bearing before tightening several other mounting bolts into position to fix the propeller shaft. Confirm that the reference marks on the rear propeller shaft track with the rear differential yoke. Put the rest of the bolts and washers between the propeller shaft and transfer case flange into position before tightening them to 35 Nm (25 lb ft). Install all remaining connecting bolts which secure the propeller shaft to the rear differential yoke by torquing them to 50 Nm (37 lb ft). The vehicle descent should begin by removing all vehicle supports.
