Disassembly
1. Remove the driveshaft.
2. Separate the front driveshaft from the rear shaft.

3. NOTE: The bolt heads are serrated. Hold the bolt and loosen the nut.

Index-mark and remove the flex coupling-to-driveshaft bolt nuts, the flex coupling-to-driveshaft bolts and the flex coupling.
^ Discard the flex coupling. Retain the flex coupling-to-driveshaft bolt nuts and flex coupling-to-driveshaft bolts.

4. CAUTION: Do not clamp the vise on the driveshaft tube as a fracture can result.

Position the driveshaft end yoke in the vise jaws.






5. Insert the special tool inside the alignment bushing and expand the collet.






6. Install the special tools.






7. Hold the forcing screw and tighten the forcing screw nut until the alignment bushing inner core is removed.






8. Discard the alignment bushing inner core.
9. Insert the special tool and expand the collet to seat behind the bushing shell.
10. Install the special tools.
11. Hold the forcing screw and tighten the forcing screw nut until the alignment bushing outer shell is removed.






12. Discard the alignment bushing outer shell.

Assembly

1. NOTE: Install the alignment bushing with the seal facing outboard.






Using the special tools, align the bushing with the driveshaft.
2. Using the special tools, drive the alignment bushing until the tool contacts the end yoke face.

3. CAUTION: There are 6 bushings in each flex coupling. Three of the bushings protrude from one side of the flex coupling and 3 protrude from the other side. The arrows on the side of the flex coupling point toward the protruding end of the bushing. When installing the flex coupling, the protruding end of the bushing must seat in the driveshaft flange counterbore or damage will occur to the flex coupling during driveshaft operation.

Install the flex coupling.
1 Position the protruding end of the bushing against the driveshaft flange.

2 CAUTION: The bolt heads must seat against the driveshaft flange and the nuts against the flex coupling.






Install the flex coupling-to-driveshaft bolt nuts and flex coupling-to-driveshaft bolts in their original locations.

4. NOTE: The bolt heads are serrated. Hold the bolt and tighten the nut.

Tighten the flex coupling-to-driveshaft bolt nuts and flex coupling-to-driveshaft bolts.
^ Coat the bolt threads with Threadlock 262.
^ Tighten to 81 Nm (60 ft. lbs.).
5. Repeat for the other end of the driveshaft.

6. CAUTION: Align the index marks or driveshaft imbalance can occur.

Assemble the front driveshaft to the rear shaft.

7. CAUTION: Add 1 gram of grease to both alignment bushing cavities before installing the driveshaft.

Install the driveshaft.
