  1. Raise and safely support the vehicle.
  2.  
  3. Mark the driveshaft in relation to the rear axle flange. If necessary, mark the relation of the driveshaft to the transfer case flange.
  4.  
  5. If equipped with a center bearing assembly, remove the retaining bolts and the spacers under the center bearing bracket, if installed.
  6.  
  7. Remove the attaching bolts and disconnect the driveshaft from the rear axle flange.
  8.  
  9. On 2WD models, slide the driveshaft rearward until the slip yoke clears the transmission extension housing and remove the driveshaft. Plug the extension housing to prevent fluid leakage.
  10.  
  11. On 4WD models, remove the bolts attaching the driveshaft to the transfer case flange and remove the driveshaft.
  12.  

To install:

  1. On 2WD models, lubricate the splines of the slip yoke. Remove the plug from the extension housing and install the driveshaft assembly. Do not allow the slip yoke to bottom on the output shaft with excessive force.
  2.  
  3. On 4WD models, install the driveshaft to the transfer case flange, aligning the marks that were made during removal. Install the attaching bolts and tighten to 61-87 ft. lbs. (83-118 Nm) if equipped with constant velocity U-joints or 12-16 ft. lbs. (17-22 Nm) if equipped with double cardan U-joints.
  4.  
  5. Connect the driveshaft to the rear axle flange, aligning the marks that were made during removal. Install the retaining bolts and tighten to 70-95 ft. lbs. (95-129 Nm).
  6.  
  7. If equipped, install the center bearing attachment bolts and tighten to 27-37 ft. lbs. (37-50 Nm). Make sure the center bearing bracket is installed "square" to the vehicle. If spacers were installed under the center bearing bracket, make sure they are reinstalled.
  8.  
  9. Lower the vehicle.

  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. With the vehicle in NEUTRAL, raise and support the vehicle.
  4.  
  5. Index-mark the driveshaft flange and rear axle pinion flange.
  6.  
  7. Index-mark the driveshaft and the extension housing.
  8.  
  9. Remove the four bolts.
    WARNING
    The driveshaft flange fits tightly on the rear axle pinion flange pilot. Never hammer on the driveshaft or any of its components to disconnect the driveshaft flange from the pinion flange. Pry only in the area shown, with a suitable tool, to disconnect the driveshaft flange from the pinion flange.

  10.  
  11. Using a suitable tool as shown, disconnect the driveshaft flange from the rear axle pinion flange.
  12.  
  13. Lower the driveshaft and slide it off the output shaft.
  14.  
  15. Plug the extension housing to prevent fluid loss.
  16.  

To install:


WARNING
If new bolts to retain the driveshaft to the axle are not available, coat the threads of the original bolts with Threadlock and Sealer EOAZ-19554-AA or equivalent meeting Ford specification WSK-M2G351-A5.


WARNING
The driveshaft flange fits tightly on the rear axle pinion flange pilot. To make sure that the driveshaft flange seats squarely on the pinion flange, tighten the bolts evenly in a cross pattern.

  1. Continue the installation in the reverse order of the removal procedure. Torque the bolts to 83 ft. lbs. (112 Nm).
