How many foot pounds for a pinion nut?
It takes about 300 foot pounds to crush the sleeve initially. After it has been properly crushed (by checking the rotating resistance of 19-22 inch pounds on the pinion) there should be at least 150 pounds torque on the pinion nut (or else you pull it apart get another crush sleeve and start over).
How is torque measured on a pinion nut?
There is no actual torque spec for the pinion nut. You tighten it until you get the correct amount of “drag” (actually called the pinion bearing preload) on the pinion bearing. This is measured in inch lbs with a dial type torque wrench.

The rear pinion bearing must be pressed on the pinion shaft and the pinion races must be tapped into the housing with a large punch so that they seat evenly. Install the front bearing and carefully tap the pinion seal in place with an old race.
Can you change the bearing preload on a pinion nut?
If the new yoke and old yoke are as little as .005 inch different in thickness then your pinion bearing preload will be way off. Torquing the nut will not change the bearing preload.
Do you have to use crush nut on pinion shaft?
You have to be super careful no to overtigthen the crush nut. Or get a solid one and some shims. Once the pinion nut is out you have to re-setup the gears to make sure they mesh right. I use Lock Tight on the ring gear bolts, pinion nut and retaining bolt.
