Good writeup, Encho!
On mine, I spent sooooo much time and cursing getting the snap ring out of the inside of the hub to pull the auto hub out. There were no pins, nothing on mine. Tried small screwdrivers, picks, whatnot. Finally got it out. Both sides were like that... bad!
The sensor, as you have probably figured out by now, is the ABS pickup.
I did notice that there was no mention of the most ignored bearing in the Dana 44 IFS... the little pilot bearing inside the spindle. It supports the drive axle in the spindle, and it rotates when the drive axle is engaged. Poor little bearing, it works hard in the dark, never gets any credit, never gets cleaned, inspected, or greased 'cuz everyone forgets about it

The Pilot Bearing is hidden inside the hollow spindle. The only way to pull it out is from the backside of the spindle, with a small internal (pilot) bearing puller after the spindle is taken off. Finding the correct seal for it, and the correct spacer was a pain. Wish I would have wrote down all the correct part #'s when I did it, as the local Ford parts counter thought I was from Mars or somewhere when I started talking about it. I got the feeling from them that I was delving into an area where no one they knew had gone before. Not the first time for that!
Didn't give me a good feeling that their garage ever did it either. At the time I searched on internet forums for it and came up with about zero. Out of sight, out of mind I guess. But I would think that somebody would realize that the axle stub shaft has to be supported by a roller-type of bearing in there. The maintenance chart mentioned it.
I wonder if some of the problems with automatic hubs may have been due to neglected pilot bearings, that then wore out and allowed the axle stub shaft to move around, breaking or prematurely wearing the auto hub guts. Don't know for sure, just thinking.

Right above the picture of the parts boxes:
- I replaced another bearing... a small one in the passenger's side spindle, i just can't recall the number (size).
Once this is done, take the nuts out to release the spindle, once the spindle is out, check the spindle's rear bearing and replace the seal. My spindle bearing was rust/dirt shut, and probably the cause of the chirping noise, so i replaced it.
Thanks Encho
