Raise the vehicle and support it securely on jackstands. Remove the catalytic converter. Take off the heat shield above the catalytic converter and the rear cross bar. Loosen the emergency brake cable adjuster and detach it from the cable. Disconnect the emergency brake cable spring from the rear crossmember. Remove the rear sway bar-to-frame hold down nuts and allow the sway bar to hang down. Mark the driveshaft and pinion flanges with paint to ensure the shaft can be reinstalled in its original position, as the driveshaft and companion flange are balanced at the factory and must maintain their original alignment. Loosen the rear flange nuts; it is not necessary to hold the bolt heads since they are secured by the flange casting. Remove the bolts and lower the driveshaft while sliding it rearward from the transmission extension housing. Installation is the reverse of removal, ensuring the aligning marks on the flanges match. To correct an unbalanced shaft, remove the driveshaft and eliminate any undercoating or foreign material that could affect balance. Reinstall the driveshaft and conduct a road test. If vibration persists, disconnect the driveshaft at the differential carrier companion flange, rotate the flange 180°, and reinstall the driveshaft. After installation, perform another road test, and if vibration continues, replace the driveshaft assembly.
