Yeah, I don't know what more the average joe could do then a full float Diamond housing with RVC shafts. In my case, get a better mechanic.

Apparently running the wheel bearings in oil instead of grease is the cure.
Still not understanding why there would be a difference since front wheel bearings run in grease and they don’t usually cause an axle to heat up and break.
I've had full floating axles fail to seat down all the way. Basically what happens is the seal butt's up against the ledge that its supposed to ride upon. Once on the ground the wheel seated the seal onto its ledge, but then the bearings were loose by the width of the seal.
I caught it before it left the shop. It was a firewood dump truck so it would have been bad.
The bearing being loose would allow too much stress on the axle shaft and eventually it will break.
It's not a swivel.

I got some cryo-treated rear axles from Poly Performance a few years back, haven't broke one yet.Yeah, I don't know what more the average joe could do then a full float Diamond housing with RVC shafts. In my case, get a better mechanic.
So the passenger side axle broke. Happened on a very modest railway overpass at 40ish mph. No noise prior, no warning signs, just a sudden loud bang and loss of forward propulsion. On the ride back with the wrecker I realized I could engage the rear locker and that should move it into the shop. Sure enough that worked, but the passenger side was not happy.
We're looking at either a custom 40/55 width FF housing or a new 70 series FF housing. Going to try and keep it as much Toyota parts catalog as possible. Likely will go with RCV axles in either scenario though. Steve is heavy.
Glad this happened to me during the shake down miles instead of when Don had the truck. It's a setback, but an upgrade will make Steve more reliable down the road.

Closing the loop on the issues with the DBW for anyone's future reference. The motor came out an Envoy, not a truck. It was shipped with a truck pedal and TAC. There are differences between generations and car/truck that most people are aware of that you need to use the appropriate pedal/Tac combo. I learned that an Envoy is not considered a truck as far as programming goes since it's pedal is slightly different apparently - and the engine supplier obviously didn't know this difference as well since they shipped it with a generic truck pedal and Tac.
If you know that you have a truck pedal/Tac, the ECU can be programmed accordingly. The Envoy pedal is plastic and you can't modify it easily to fit like you can the steel truck pedals. In trouble shooting I could see the throttle was opening at inconsistent and sometimes large percentage increases with very minimal movement, this would cause inconsistent references between the expected app signals causing the ECU to throw a code and put the engine in limp mode. I could only get this behavior while driving, never when parked.
Here is the video Don referenced after the ECU had been programmed with the truck pedal and everything functioned as it was expected to.

Something I didn't know, but love learning stuff like this.

Jinkees!
I will be watching for the next chapter...
They were repaired earlier in the year. After I got the axle done, I decided it needed air bags. The bags are installed, but I've been busy with other stuff and haven't finished running the air lines. I've been building a rabbit coop for meat rabbits. I would like to do some Fall camping though.
