I've attached a .pdf file of the system's operation and diagnosis as it applies to an '04. Lots has changed on the '17+ models, but I *think* the 4WD system operates in the same fashion.

They did make a more reliable system with the manual shift transfer case and manual locking hubs. I don't think they offer the manual 4x4 on the newer trucks. The general public would rather have something convinent than something reliable.

Having a vacuum or electronics to engage the hubs and transfer case will never be as reliable as doing it manually. I just lock my hubs before I leave if I think I am going to need 4x4 where I'm going, then I just shift into 4x4 when I need it.

My last truck was all manual. I went with ESOF this time. Try something new. The xfer case motor seems easy to get to. I haven't heard of the ESOF's failing much around here, give or take the hubs, that can be locked.

It is a $0 option for 2018 XL Super Duty's.
The general public is to stupid to actually lock in hubs and shift a lever...

I have no worries shifting into/out of 4h at speeds. In both my personal trucks as well works trucks. My 2008 would sometimes make an audible clunk.
I do let off throttle when engaging/disengage, but anywhere between 80-100kmh I do on a daily basis.

My personal opinion is to not have any torque on the drivetrain while shifting...
We don’t all live and drive in ideal conditions where getting in/out of a vehicle on a hwy is safe and/or convenient everytime ya wanna be in 4x4!

As for those that complain about the whine you have to realize there is a chain in the transfer case spinning really fast right under your seat.

Whine
Whining in mine is in-sync with acceleration/deceleration with a metallic type humming. No issue with clunk or loud noises. Different than previous fords. Riding with a ford mechanic this morning to try and pinpoint it.

There is something about "An object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force", that makes me nervous when people pass me in the snow on the highway.

I find it ironic that some manufacturers would ask, "Hubs? What are hubs? our system has no hubs." It's obvious to me, many here have no idea how to use the 4wd system based on the comments that are typed above. I'm now wondering who are the stupid ones...
