Please explain how I would disconnect them and I’ll be happy to test this theory. I peeked down there today and see the “motor” I guess and some wires around it. Is it a simple canon type plug?
You will see 2 black hoses going to the IWE. One IS a hose and just vents to atmosphere. The other is a wire harness. I suspect that you could just trace it back to the closest connector?

I would try putting it in 4A and then unplugging it.
Put it back in 2H and the grinding no more? Theory being that without voltage/signal, the stepper motor can't disengage the IWE?

Bummer, mine's the tremor and has the specific half shafts. I'm surprised more Tremors don't have the issue, but ti does seem like it's becoming slightly more frequent.
I have a ‘21 tremor and have the same/similar issue. I found this tread from the Tremor Forum.

Been experiencing a hum/howl from the front left of my 2022 F150. It’s happened 4 times now over the 5 months I’ve owned it. 3 times at the exact same spot, going 45mph and slightly turning right. It sounds like a wheel bearing hum or howl that lasts for 15-20 seconds then goes away. Almost sounds like going over a rumble strip on one side. The last time it happened I put it in 4wd and it immediately went away. Anyone else experience this before? 3800 miles
I have a 2023 F150. Started doing this 3 days after I left the lot at 600 miles. Did is several times over a week so I took it in for service. They said they couldn’t find anything wrong but some loose panels in the undercarriage. They literally drove it 2 miles. This is so infuriating! I got a video of the noise (just sounds like humming or rumbling, but it’s louder first hand) I’ve had it back for 10 days and it’s done it several more times. Taking it back in, service appointment for 3/11/24. They literally told me just to drive it until it breaks but that’s not going to work for me. Why buy a brand new truck just to wait for it to break down? This is my 3rd f150 since 2019 and I am less then satisfied with the whole deal.

Been dealing with this issue since last year as well. For me, it's a rubbing noise at slow speeds (<30 km/h) and turning slightly left, about an eighth of a turn. Dealer has made multiple attempts to fix and is stumped. Hopefully Ford can release a fix soon....

That's odd. Your truck shouldn't even have IWE front hubs. Now I'm really curious.

That’s correct, I verified that I do not have IWE and I’ve had this problem for a while now. Thought it was maybe factory pirelli tires, so I replaced them. Still having problem. Feels like a wheel bearing. I feel like it isn’t as bad though when the truck goes into electric driving.

Hi Folks, my truck has been back from the dealer for a week now and the noise is gone. They said mine was the first truck that they've done this procedure on, but they're optimistic that it'll work. Apparently the hotline had run out of suggestions, and this one came from engineering. Hopefully it helps you, because I for one am tired of going back and forth to the dealer for this

Add another, 2021 30,000 miles, it may have been doing it this whole time but I haven’t really noticed until now. Colder weather seems to aggravate the issue.

Most noticeable in colder temps, morning time, and first 5 or so miles of my drive, while coming to a stop, like 20mph and down. Sounds like a very low frequency hum/buzz/vibration as if my tire is faintly rubbing on my wheel well plastic on drivers front.

It is intermittent and sometimes comes in and out while it’s doing it, it is however much more noticeable with radio off and climate fan off on smooth pavement.

This is exactly my issue as well. '21 with 27k miles.

Interesting! Going to bring this up to dealer! Be great to get an update from you after a month or two!

Thanks for sharing!

brought my truck in today for the same issue, you turn to the right and accelerate slowly it makes what sounds like rubbing noise, you can feel it constantly in the gas pedal. in 4wd no issue but only in 2 wd. hopefully they can solve this issue or diagnose it today because it drives me crazy.

After taking mine to dealer, they said they couldn’t replicate the issue. They said it did sound like EIWE from the problem description. They replaced both actuators under warranty. It was mentioned that the teeth on old actuators had been damaged. Have had it back for a few days now with no issues. Dealer said they couldn’t guarantee this would fix the issue as they have replaced full front ends on trucks not being able to fix. They said Ford is certainly aware of it and just a matter of time until there is a fix.
