This is one of those rules that doesn't make sense. Particularly when someone is trying to find a part.Since you are not allowed to post auctions/Craigslist or any of the other sites I'm just guessing that is why no post about which one.
Pretty good observation! I was stressed out about it until I drained all 3 diffs and all 3 had the exact same thing on the drain plugs. After talking to a few people familiar with these trucks they do have lockers and in the manual it clearly states “Do not engage additional axles while spinning a tire, damage may occur” and that’s what we are theorizing has happened. Small chunks of the locker, I inspected the bearings with a snake camera they all look good from what I can see. I’ve changed the fluid and will keep a close eye on temperatures. Probably will run the fluid another 500 miles or more, then drop it and inspect it by running through the centrifuge to see what kind of wear particles are presenti can't really see the particles on the magnet well enough in the video but if they are flakey im gonna guess you are loosing a bearing race, the surface is damaged and is coming up and being rolled flat by the bearing rollers, the rest of the bearings may or not survive ingesting the metal as it is circulated by the fluid, their races may look pitted slightly by the embedded metal particles, the gearset will likely be fine unless its run till the failed bearing has a major failure and comes apart loosing containment of either the pinion or carrier positioning, then the gears will loose alignment and eat one another.
i don't have experience with a diff near that large so this is speculation based on upscaling 1/2 and 1 ton diff and transfer case failures
Update on this, truck is insured through State Farm with no problem, 300k coverage across the board and less than $140 a month for commercial insurance. No word on the sf97 yetHow are you registering and insuring this truck in Georgia?
Weird- I can change mine from my cell phone. I have an android and I use the "Full Site View" when using this sight which is different than the short hand version. I don't know about iPhones & Tapatalk though...Haven’t been able to update it in a longggg time because I don’t have a desk top

Neat truck! It was fun seeing it at the rally.Gave her **** at the Georgia Rally, rebuilt the compressor aftercooler and air dryer; crazy how much of an improvement these trucks are over the 5 tons. I put it through the worst I could for over 100 miles offroad this past week and I couldn’t phase it, had some traction issues due to non-op ctis but after I aired down the truck was almost unstoppable.
