I grew up with the full sized chevy blazer K5 in the 70s. If you wanted 4WD, you stopped the vehicle, put it into 4W mode, got out and turn the hubs on the wheels, and got back in. Your push-button 4WD is akin to this. But I’m not convinced the new Bronco’s 4A button is akin to not having to press the 4WD button / getting out and turning the hubs.I want to throw in a silly anecdote that I've told before. 30 years ago (yow, that long? Now my head hurts), my family had a red over red 1991 2-door Explorer Sport. 4.0L, 5-speed, the first push-button 4WD vehicle my parents had owned. Dad was/is a big advocate of hubs that have to be locked in. Anyway, one winter, my mom wiped it out driving to work in the snow, hit a tree with the right side. Dad asked "where you in 4WD?" "No". "why not?" "I didn't want to use it all up".
Teasing Mom about it aside, it underscores the point someone else made in that most people have no idea how these things work. So it became very important to develop AWD systems that just work on their own without driver input. That's probably not in question, but it is exactly why the 4A option exists. The '91 was replaced with a black '98 Explorer Sport, this one with an automatic trans because that was paired with Ford's then cutting-edge "Control-Trac" system. The first 4A t-case used in midsized Ford SUVs. So, there's nothing truly novel or scary about 4A, it is just an ever-refined version of what's been around for decades.
It may be missing in this thread, perhaps, but it's been covered in numerous other threads, the vehicle manual, and Ford's website. It's not a secret.What’s STILL missing for me in 2022 reading this 2021 thread is whether it’s safe to use 4A on the pavement, in the rain, for example.
Thanks. I read some F-150 forums on “4A” which said “no faster than 15 MPH” which, frankly, seems like a typo and should have said “4H”. Right?It may be missing in this thread, perhaps, but it's been covered in numerous other threads, the vehicle manual, and Ford's website. It's not a secret.
Of course it's safe to use 4A on pavement, in the rain or when it's dry. That's the point of 4A.

From the massive JalopNick article reference here, which is a great read, it seems that the Bronco’s 4A is “On-Demand Active AWD — Transfer Case-Based“; is that right?
Who manufacturers the Bronco’s “4A” transfer case — BorgWarner?

Not to belabor this thread and the point of 4A and all the other thread herein and on other sites …Sounds like misinformation (to use the trendy terms) is everywhere. Why in the world would you not be able to use 4A above 15 mph? The Bronco engages 4A (if available on that Bronco) when Sport Mode is selected!
Yes, I believe 4A is active, on-demand. Clutch based, controlled by the computers.
