Just wondering if anyone ever found that these propeller shaft bolts needed to be retorqued and at what mileage if you did find that they had loosened up?
Anyone ever retorque their flange bolts on the driveshaft?

Not unless I've had the DS off for new joints or something. Then I check them. Did you find some loose ones?
Check them on the cruisers every time I lube. Happy Easter Mike
Red loctite...and check them every time I take it out...they always come loose...even replaced them...Now on the P/U or Runners...never...always tight...same bolt almost...weird.
I check mine every few months. They have never been loose.
when I got my truck one was gone so keep a eye on them

I wondered how you would get a torque wrench in there?
You can't get a socket on there (at least I couldn't). You need to get a box wrench type adapter for the torque wrench and adjust the torque settings accordingly.
See page 5 for a good example:

Cool, thanks, I've been mulling a product that would need a special torque wrench adapter to install. This has all the info I'd need for an installer, just need to make the adapter.
If you don't trust yourself with the math, here's a site with a pre-built calculator:

Cool calculator. I guess the internal workings of a torque wrench are not what I thought. If I put a rotary strain-guage on the square drive, the calculations would be different than this for adding a torque multiplier.
I'm not 100% sure I understand what you are saying. But don't torque multipliers get their advantage via planetary gearing through the same axis as the square drive? In other words, the distance between the force and the square drive does not change.

I've watched maintenance change wheels on airliners, they use a simple extension on their torque wrench, no gears. Square hole in one end, square drive on the other end, probably Snap-On. They have a laminated conversion card in the case with it. I know the type you're talking about, more complex. I need one for small Allen screws, just to reach in where the head of a torque wrench won't fit, kinda like our driveshaft bolts.
