Ford 8G1Z-4R602-B
Drive Shaft, Rear

The first step of drive shaft replacement involves indexing the two flange ends. First put the vehicle in NEUTRAL position while it rests on a hoist then remove the muffler and tailpipe followed by the 4 exhaust support brace bolts and the exhaust brace which need to be tightened to 30 Nm (22 lb-ft) torque when reinstalling. You should use new bolt-washer assemblies during installation of the rear constant velocity (CV) joint flange while discarding the original 3 pinion flange bolt and washer assemblies that require 25 Nm (18 lb-ft) torque during installation. You must detach the driveshaft CV flange from the Rear Drive Unit (RDU) flange by using a flat-blade screwdriver. Keep the new bolts in storage as the CV joint bolts cannot be reused. After removing and discarding the 4 driveshaft-to-Power Transfer Unit (PTU) flange bolts install new ones with 70 Nm (52 lb-ft) torque. A suitable prybar enables the separation of driveshaft flange from PTU flange before technicians remove the 2 outer center bearing bracket bolts and driveshaft while assisting each other to tighten the bolts to 30 Nm (22 lb-ft) torque upon reinstallation. To proceed you should take out 2 inner center bearing bolts along with the bracket as you will need to tighten them to 20 Nm (177 lb-in) upon reinstallation. Vibration in the driveshaft after installation should be addressed by indexing it followed by the backward execution of the removal steps before reinstalling.

At the start of driveshaft maintenance you should write reference marks on both driveshaft flanges. You should place the vehicle in NEUTRAL position before hoisting it for muffler and tailpipe removal. The next procedure requires removal of the 4 exhaust support brace bolts in addition to the exhaust brace before tightening the new setup to 30 Nm (22 lb-ft). Fitting fresh bolt and washer assemblies at the rear constant velocity (CV) joint flange prevents vehicle damage because you should remove and eliminate the 3 existing CV joint flange bolt and washer assemblies before installing new ones with 70 Nm (52 lb-ft) torque. It is necessary to replace all constant velocity (CV) joint bolts as you remove the 4 driveshaft-to-transfer case bolts and secure new ones with 70 Nm (52 lb-ft) torque specification. Two helpers are needed to remove 2 bolts from the center bearing bracket along with driveshaft removal before securing new bolts at 30 Nm (22 lb-ft). You can tighten the new installation by 20 Nm (15 lb-ft) after removing the 2 center bearing bolts and the bracket if necessary. Once driveshaft vibrations appear after installation users must index the driveshaft before reattempting the drive removal procedure for final installation.
