OK you want the output shaft pinion nut torque. There isn't a number for that, you actually need to measure the amount of torque it takes to rotate the shaft while it is installed and assembled. Then you install the new crush sleeve and tighten the nut until it takes the same amount of torque to rotate the shaft.
From Ford -
NOTE: Rotational torque of the Power Transfer Unit (PTU) rear output shaft flange must be measured and recorded using a Nm (lb-in) torque wrench for correct pinion bearing preload when reassembled. This will be the torque-to-turn measurement.
Using a suitable torque wrench, measure and record the rotational torque of the Power Transfer Unit (PTU) output shaft.
Now you remove the flange and replace the worn parts and crush sleeve, then
Install the output pinion flange.
NOTICE: Refer to the rotational torque previously recorded with the Nm (lb-in) torque wrench. Tighten the pinion nut in small increments until it is within 0.3 Nm (3 lb-in) of the reference measurement. If 0.3 Nm (3 lb-in) is exceeded, then the collapsible spacer will be damaged and a new collapsible spacer will be required.
However in the PTU rebuild section it shows this if you are using new parts-
Install the output pinion flange.
Using the special tool to hold the output pinion flange, install a new pinion flange nut.
