I was avoiding responding because I have been busy. But you suckered me by
buttering me up.

This simply means to put the front end back in the front, and the back end
back in the back.
It is much better if you can line up the holes too, and put each bolt hole
back to the same bolt hole to which it was previously attached.

After attaching the driveshaft, wiggle the front diff around as much as you
can and then try to make it strait. Then retighten the bolts holding it there.

The text string "visually assuring that the driveshaft does not bind before
tightening the final drive bolts" is not meaningful to me.

They are supposed to be replaced, but nobody does. As Tim Smith says, just
loctite them. Or go overboard and buy a box of them from Mr. Metric to keep
costs down, and then change the nuts every time you take the drive shaft
out. This is what I did.
Trick to getting the nuts off: try using a 1/2 inch wrench rather than the
metric one. It is a little tighter and can get the nuts off when the
regular nuts won't comeoff.

You will have to remove the nuts from the front of the driveshaft but not
the rear of the driveshaft.
