The outer end is supported at the axle stub by the inner spindle bearing (needle bearing).

You would be suprised at the amount of magnesium auto manufacturers are using now a days. I am a chief in the FD up here and we see magnesium in car fires alot. All makes all models. I have yet to see a SD burn so I cant say for sure there.
You will know when you have a magnesium fire and dont use water it will cause it to explode...I speak from experience.
We use Metal-X extingiusere to put out the magnesium if its burning.
To the OP, I am also going to jump on the failed bearing band wagon. Those parts are available A/M and if you are mechanically inclined you can do it your self. Hopefully WARN comes through for you cause I was going to put a set of those on my truck and a success story would be nice to hear.

Yeah, hopefully Warn comes thru not because of the warranty but because of "goodwill" in bad economic times and the OP's loss of employment... Did you find a job 5.4L to Freedom?

My vote is on the wheel bearing going. I've had that on 3 super duties now, and can speak from experience, that sucker get's dang hot!!! Thing is though, and I dont want to criticize anyone, but when the front wheel bearing went, on all 3 of them, it made a hell of a racket. So, I'm going to guess it wasn't just a sudden event that caused this carnage. And I hate to say it, but I wouldn't blame Warn if they denied your request, the warn hub didn't cause that, and you kept driving it after you heard noise and saw smoke, so the melted hub is collateral damage to the decision to keep driving it. Hate to be so blunt, just calling it as I see it. Break out the checkbook, cuz that's going to be a spendy repair, and probably would have been a bit cheaper had you stopped driving it when you heard the noise and saw the smoke...

I believe the dynatrac would do it because the inside of the wheel bearing is replaced with a spindle.

Nobody would have a wheelbearing problem if they greased their wheel hub and needle bearings once in a while. That grease doesn't last forever. At least wiggle the wheel once in a while to make sure it is all snug. I doubt if Warn will help you on this.

Would be nice if they were greasable too. Ripping the whole damn hub apart just to lube bearings is a PITA and if you pay someone to do it it will cost a fortune. As the years go on and on, vehicles are being made more and more towards being completly throwaway vehicles with throwaway parts.. Grease fittings and dipsticks are being dropped like hot potatoes. My 74' has tons more greasable parts than my SD. Maybe even seal the hub and run gear oil in it.

By "greaseable" I mean grease and external grease fitting. I know you can tear into the hub and grease the bearings it would just be nice if you could put a couple shots of grease in every oil change or every other oil change to keep things lubed. I got bearing buddies on all my trailers and they are the chit for keeping the bearings greased.
