I performed a Google search "why retorque propeller shaft bolt". The first 30+ references are links to Toyota forums. No other manufacturer is mentioned on the first page of Google hits. I elected to read forum posts on 8 links to compare my experience with others.
Almost nobody retorques these bolts including many dealers. Those that check the torque debate two approaches (1) loosen and retighten, or (2) do not loosen and simply check for tightness. Most prefer the latter. Personally, I prefer the latter and I performed this check with simple hand tools at 100,000 miles. Nothing was loose.
Torque spec is 65 ft-lbs. There is a risk of rounding off the bolt if cheaper tools such as a lower quality crowsfoot is used.
The actual torque applied when using a crowfoot or box end extension on a torque wrench must be accounted. Furthermore, the extension must be parallel with the torque wrench. See
