- Raise and safely support the vehicle.
- Mark the position of the driveshaft yoke on the axle companion flange so they can be reassembled in the same way to maintain balance.
- Remove the flange bolts and disconnect the driveshaft from the axle companion flange.
- Allow the rear of the driveshaft to drop down slightly.
- Pull the driveshaft and slip yoke rearward until the yoke just clears the transmission extension housing seal. Mark the position of the slip yoke in relation to the transmission output shaft, then remove the driveshaft.
- Plug the transmission to prevent fluid leakage.
- Lubricate the yoke splines with suitable grease.
- Remove the plug from the transmission and inspect the extension housing seal; replace if necessary.
- Align the slip yoke and output shaft with the marks made at removal and install the yoke into the transmission extension housing. Be careful not to bottom the slip yoke hard against the transmission seal.
- Rotate the axle flange, as necessary, to align the marks made during removal.
- Install the driveshaft yoke to the axle flange. Install the bolts and tighten to 71–95 ft. lbs. (95–130 Nm).
- Lower the vehicle.
