Locking Transfer Case

[Nickp]

From the BlueOvalForum user /r/My93SHO. It seems as though our very own /u/Escape_Artist actually deciphered this!

Now, I was not honestly familiar with what a transfer case lock was. So I did some reading... sounds like the basic gist of it is that a jeep/most other vehicles the transfer case is locked by default. Meaning just like how with diff locker the left and right tire move at the same speed... a locked transfer case means the front axle/IFS(que the damn chairs lol) and the rear axle have to move at the exact same speed. Hence the jumpiness that I'm sure you've felt if you've ever tried to drive in 4x4 on a high-traction surface. By unlocking the transfer case, this allows the axles to receive different amounts of power, so you could be in 4x4 even on paved surfaces.

Sounds pretty fucking cool to me!! Now this is all speculation we can't see it well enough to be sure that's what it is... but odds are pretty decent IMO.

Edit: I’d assume it’s similar to how Mitsubishi’s system works;

Since their are 3 pictures of what appears to be locking diffs it would make sense that one is for the transfer case

Also that's my picture from the interior leak thread lol. They must have stolen it for the blueoval forum

Hmmm
That would be nice to have, wonder how high of a trim would have that ability or is it a option on most trims?

 

[Escape_Artist]

Thanks for the credit Nick. Now we need to figure out who our spy is

And Amos I would expect this on most trims to a certain extent. I imagine all trims will have a locking rear. And obviously they will all have traction control and hazards.

I honestly have no idea. TBH I would probably assume it will be an option and the standard Bronco will just come with the ranger t-case. But we also don't know if it is a manual shifted or electronic shifted t-case.

hey nick, I literally was asking this question, in the interior thread, as you were starting this thread. LOL

Thanks for clearing it up for me.

edit: maybe the admin can move it over to this thread.

Yeah it is !! but I can see how they will govern it because the average joe is an idiot, but I would like to be able to control what gets locked and when. I am sure that you will have to lock the transfer case before you can lock the rear diff because of the ill handling that comes from having the rear diff locked in just 2WD but DAMN IT sometimes I want that. needs to be an override switch or something so I can do what I want.

Maybe the Warthog will have less constraints on it seeing the crowd it is geared for.

That’s it! I’m buying reading glasses!!
Damn millennial must have made that video!

Except in the Raptor, where you can have the rear diff locked at high speed if you're in the right mode. Hopefully the rear and center diff here will be the same way! Otherwise...I know what I'll be wiring my toggle switches to...overrides for the diffs.

One key thing is on the Mitsubishi system, when not locked, you get a viscous limited slip center differential (sort of like what Subarus have all the time). I'll be curious what the center diff is on the Bronco when NOT locked. On the Raptor in 4A, it's sort of a clutch type LSD, hopefully it's not just open when not locked on the Bronco.

To me, button on the right of the rear lock looks like “turn assist”. Lexus has the feature in the LX570. Basically a “cutting brake” to allow tight turns offroad. That looks like a curved arrow on the image.

Kinda the same as it was in 78 (left knob, and no diff locks back then of course).
They didn't use locking front hubs either, they were permanently "locked" in.........

For what it's worth, Jeep's NV242 (Selec-Trac) works more or less like Mitsubishi's system.

2-hi (rear wheel drive only)
4-part time (4 wheel drive, locked center differential)
4-all time (4 wheel drive, open center differential)
4-low part time (4 wheel drive, low-range, locked center differential)

@Jalisurr I didn't know Super Select had a viscous center in 4H, that's good to know.
