There’s a member here who ponied up for the shop manual. I’ll send him a message. The only thing is; that if it’s a design flaw, it might not do any good to bother and if it’s a supplier issue and they are still using the same bolts, it still won’t matter. Or if it was only a problem impacting certain builds, you might not need to worry.
Unless people share at the very least their truck’s build date and mileage at failure, only Ford has a decent idea of what’s going on.
The only variable that I can think of at this moment that would be eliminated by swapping out the bolt is incorrect torque while perhaps also resetting your miles to failure but then again some people are having the failure at pretty low mileage and others as far as I know aren’t having the failure with many hard miles. So you’re potentially setting yourself up for failure by swapping the bolt, which might be why Ford hasn’t done anything so far.
Here’s a thread discussing the failure on PB trucks:

and on the other f150 forum, there’s a thread titled: 2021 Powerboost Rear Rotor/Axle Bolt Sheared
Both contain additional speculation and information, one mentions 111 passenger side axles on backorder and a report of a driver’s side bolt failing. There’s even a mention of there being a TSB but then there’s also plenty of instances of owners being gaslighted by their dealers.
