And 80k. He is at 88k
I will say, the MGU is REALLY on there, probably because the long bolts were torqued pretty good and likely squeezed the aluminum snug.
Before anyone takes whacks at it, here's what I did because pounding at this thing probably isn't the best idea.
The following is MUCH safer and went really smoothly.
With all the bolts out, put some WD-40 on the hinge points where the long torqued bolts came out of.
Then with a curved pry bar, (see photo below) place it in the gap and push down to lift the side closest to you.
Mine pivoted on the opposite hinge point pretty easily with that kind of leverage and would only go so far with the air intake in place on the throttle body. If this happens to you, simply disconnect the intake from the throttle body and shift it out of the way.
The MGU has a friction fit threaded sleeve for the bolt threads that will back out but it's not necessary to do that for removal.
Mine came out when I was using the space as a way to separate the halves.
I had to then rock the unit back to it's original position a few times by reaching across the top and pulling it back toward me. The WD helped A LOT for that. I pryed and reset it a good 20+ times before that first circular alignment part came totally free (the part that wants to trick you into thinking it's a sleeve)
It got easy after that.
Take it easy be mindful of your pry bar position and you should have good success.
The MGU has to weigh a good 20 lbs so don't be surprised.

Everything UpNorthEngineer documented in the original post is spot on! Particularly the resolver and reluctor damage.
The tolerances in there are tight. With that amount of failed bearing movement, this damage is totally logical. Hopefully it doesn't create significant issue down the road.

I just want to thank UpNorthEngineer for being the trail blazer and posting this. Life saver!
I just finished my truck tonight and it's so smooth. A little patience and research goes a long way.
Thermal expansion and contraction with my carefully used heat gun and a $10 can of air duster to chill the shaft helped the bearing go on relatively easily.
Those of you out of warranty don't be afraid to give this a shot. Besides time, I'm only $30 invested.
I went with a Timken 6003-2RS-C3. Well see how long it lasts.
Best of luck everybody.

Ford has and had i issue with the duel clutch trans in the focus. they knew it and sold the cars anyway thinking a fix would be found but a fix never happened internal documents were found in discovery for the class action reviled they knew all about the issue and pushed the cars out anyway.

kia's have main bearing issues they replace motors left and right turns out the bearing supplier was the issue.
i bet a combination or something similar is going on here.
till the cost of repair exceeds the cost of a legal battle nothing will be fixed. they will just throw a Band-Aid on it till you are out of warrantee then you are SOL.
it would be nice if they admitted some fault or found something to blame it on and had a updated MGU that has a better bearing or something. not everyone has problems so i imagine they have more than 1 supplier for the bearings that have issues and 1 of them suc or it's just a pis poor design.

We'll never know. I'm just glad bearing replacement was a task that was doable. Not that challenging after all. Take that Stellantis, who needs you!
With all the bearing failure's it's made me wonder if bad bearing supply is the issue or the bearing is the weak link / sacrificial lamb of engineering that failed due to stresses of the unique system and odd tensioner setup.
