What do I have when the diffs aren't locked?

[Jdyount]

Ok so a few things:

1. Limited slip (positrac) may have been the shit in someone's 1968 Camaro but limited slip doesn't work with larger tires. Too much rotational mass, you'll smoke the clutches in the posi instantly.
2. No, you can't have an e-locker and posi at the same time.
3. Yes the Bronco has advanced traction control, yes it is 100 times better than any posi (unless you wanna do burnouts, in a car, with car sized tires).
4. If you think the advanced traction control and GOAT modes aren't useful in the Bronco you are the same type of guy who only owns 1 hammer and uses it for everything. Sure, when you don't need the advanced traction control and are just doing general offroad stuff, going into 4 LO is fine, but the advanced traction control is ABSOLUTELY useful in lots of different situations. Sand is the very best example, it is a NIGHT AND DAY difference without the advanced traction control programing built into the GOAT modes in sand.

Base bronco vs Base Jeep

In the first 3:30 minutes you can see a base bronco with brake lock differential action

so then it clearly does do per axle torque vectoring. thanks for the video.

Yes, the Bronco 1,000,000% has torque vectoring abilities built in. The Trail Turn Assist for example, locks up the brake on one side and lets the other side rotate.

Now, I can't tell you where exactly they implement it in other cases (what modes and how), but it absolutely is a feature that is there.

The only thing unclear to me is Tommy's 1st edition (loaded) slip tests showed it only happened on the front. That could be 1) Ford only put it on the front when you have a rear or front/rear locker, 2) the rear brakes are weak compared to the front, 3) base bronco's has it front and rear, 4) Tommy missed testing the 3 wheel slip test in 4H, 5) something else.

With Andre's test, it's hard to say which end got him through the offset pits. I tend to believe Ford is using all for rotors when it does this and Tommy didn't test well enough. I am personally glad to see it. I live in CO and it is common to be in 4L with rear locked over obstacles and I'm glad the front is differentiating based on slip.

Hmm, I've seen other videos including from TFL, which indicated little if any brake lock differential functioning. At least in 4low. I'll find those and maybe we can compare what's going on.

At the offroadeo they instructed us that traction control was disabled in 4low.

Yeah that's mostly what I've found online and what my friend ChatGPT has told me. And what I've seen in some other videos. Specifically talking about brake lock diff functionality.

Yet the video provided earlier in this chat seemed to show some traction control. I wonder if in that first part of the video, TFL has the Bronco in 4High?

Regardless, Toyota and Jeep have some well implemented brake lock diff functionality that shows the capability.

But if a person does not have a "computer controlled" solution (like me) to begin with, yours is a moot point.

The Bronco’s computers are doing things in 2H/4H.

Is there any way traction-control can be left on in 4-low?

I do not think so.... Hack the computer I suppose..... I would not want it on when in 4 low though....

To me, traction control is really throttle control. It keeps your from madly spinning tires. This has been true for most brands/models I've ever dealt with.

When the ABS circuit stops a spinning tire so the other tire can help within the differential, I call this brake lock differential intervention. I think I learned the name from my old Jeeps (JK, JL). My wife's Acura calls it torque vectoring (changing the direction of the torque). Toyota calls it A-track on my FJ Cruiser.

If Ford has a name, I'm unaware of it. I think Range Rovers started this and is generally considered great at it.

Is that true? I have an F-150 Tremor with limited slip rear differential and an E locker. And there are many Tremor owners running 35s. The front has a Torsen differential, and Yes, you can add an electronic locker (e-locker) to a front differential, including a Torsen (torsion) differential, by replacing the stock Torsen differential carrier with a new e-locker carrier and following the appropriate installation and wiring procedures. The process involves disassembling the axle, installing the new e-locker carrier and ring gear, setting up shims, checking backlash, and wiring the e-locker's switch to the vehicle's power system.

A Torsen isn't a standard limited slip, no clutches, and given it's only used in the high end stuff, (Boss 302, SVT Raptor, ect) it's probably rather expensive. It seems to be more of a Detroit Locker type carrier vs a standard limited slip.

What I was saying about an e-locker and a limited slip is that you can't use them at the same time. Can't have both carriers in the same axle at the same time. To my knowledge there is no limited slip that also has an e-locker function.
