9" pinion nut
There is no torque spec on the pinion nut - it's tightened to achieve a specific pinion bearing preload (measured in in-lbs of torque to turn the pinion gear) after the pinion has been shimmed to the proper depth. Check here: http://www.drivetrain.com/ Scroll down the L bar to "Differential & rear end parts" then to FORD, 9" in the main window.

As he said, you don't tighten the pinion nut to a specific torque. You tighten it until you have the right bearing preload, which would mean the amount of effort to turn the pinion gear. The measurement you're looking for is 22-23 in-lbs.
