Very wrong information here.

That would be 12 - 14 " pound drag on the bearing.
If you torqued the nut to 12 -1 4" pounds there would be way too much clearance.

The amount of torque to crush the sleeve is into the high 100 foot pounds.
The information is right, you just did like the way it was wrote. This is close to how the Ford manuals word it. This is from the Manual.

Companion Flange, Rear Axle Installation

1. Apply a small amount of lubricant to the companion flange splines.

2. NOTE: If a new rear axle companion flange is being installed, disregard the scribe mark on the pinion shaft.

NOTE: The rear axle companion flange must never be hammered on or installed with power tools.

Align the mark on the rear axle companion flange with the mark on the pinion shaft. Install the rear axle companion flange using Companion Flange Replacer TOOL-4858-E or equivalent.

3. Install a new pinion nut on the pinion stem.

4. Hold the circular rear axle companion flange with Companion Flange Holding Tool T78P-4851-A while tightening the pinion nut (see Step 5).



5. Tighten the pinion nut, rotating the pinion occasionally to make sure pinion bearing cone and roller assemblies seat properly. Take frequent drive pinion bearing torque preload readings until the specified preload reading is obtained.

New Bearings: 1.8-3.3 N-m (16-29 lb-in)

Used Bearings: .9-1.5 N-m (8-14 lb-in)

Under no circumstances should the pinion nut be backed off to reduce preload. If reduced preload is required, a new collapsible spacer and pinion nut must be installed.




There is not a torque setting for the nut, you just tighten it a very little at a time with the big stuff and then check the rotation with inch pound torque wrench.
