Question on Big Bend without 4A

[Beachbum]

Honestly 4a is another thing that sone people mess up. I work in a dealership and I've had some many broncos that people drive around in 4a all the time. I had to do so much work on transfer cases due to that fact. 4a is good and all but your are not supposed to leave it in that mode all the time. I never use 4a in my Outer banks

So everyone that is driving around in Sport Mode shouldn't be? Sport mode puts you in 4A.

Interesting. So are you referring to customers who just leave it in 4A, regardless of weather / road conditions? Are you in an area with persistent snow and ice covered roads?

My Bronco is acceptable in snow, in 4A, compared to my winter driver. In 2H it is a pig. I wouldn’t want to drive, to say Aspen (which I do monthly in my winter driver) over multiple mtn passes and have to rely on 2H.

Yes a lot of our customers traveling through 4 corners bring the vehicles here and they are always in 4a snow, rain, sun it doesn't matter and that mentality boggles my mind

What are you talking about man. It’s perfectly fine to leave it in 4A all the time. Is there a parasitic loss and some potential wear to driveline if you leave it in 4A for a 100k miles? Maybe. But look at how many brands have AWD only, no other modes. they are all doing fine. Same principle with the bronco.. literally tell you at off roadeo it’s okay to leave in 4A.

Sport mode does not put you in 4a.

Sport

• For sporty driving with improved performance handling and response. This mode increases accelerator pedal response and provides a sportier steering feel. The powertrain system holds onto lower gears longer, helping your vehicle accelerate faster.
• (2H) is the default four-wheel drive mode. (4L) is not selectable in sport mode.
• The front electronic locking differential is not available in sport mode.
• The rear electronic locking differential is available.
• The stabilizer bar disconnect is not available in sport mode.

This is directly from PTS from Ford.


When (4A) is selected on the ATCM , the 4WD system provides electronically controlled four-wheel drive with power delivered to all four wheels, as required, for increased traction. (4A) is appropriate for all on-road driving conditions, such as dry road surfaces, wet pavement, light snow or gravel. Shifts from (2H) or (4H) to (4A) can be made at any speed. In (4A):

• The ATCM sends a (4A) mode status to the AWD module via the GWM .
• The shift motor positions the ball ramp device at the clutch kiss point when driving conditions do not require 4WD.
• The shift motor positions the ball ramp device to apply the clutch when wheel slip is anticipated or detected.
• The reduction sleeve connects the input shaft and output shaft
• (4A) is displayed in the message center.

You can leave it in 4a per Ford, but based on what I have seen there is extra wear on the system when you put it into 4a. From what I have seen it should not cause any damage but it can. Maybe these people were unlucky but it just seems to me that if you don't need it just leave it in 2H

I'm just telling you what I see at the dealership. To each their own. If you want to leave it in 4a go ahead. I personally believe that if you don't need 4a at that moment don't use it. I'll never tell anyone what to do with their own vehicles. It is just an observation.

So when I select Sport mode and my 4A light comes on and the screen actually says entering 4A that it isn't really putting me in 4A? Sorry just trying to understand so I don't have issues down the road.

Thank you

I didn't think the Badlands has Sport GOAT mode?

Do you not have advanced 4x4 on yours? Because it does put you in 4A if you switch to sport. Every time. You have to get in sport, and revert back to 2H otherwise if you don’t want to be in 4A.

it’s just a bit disingenuous to speak in anecdotes about what you have seen in other vehicles to people who are none the wiser and genuinely seeking information. that’s a disservice to them.

No 4A in BB 4.27 locking rear. No problems, it's so simple a cave man can do it. It's a beast in the snow. It's amazing how it holds in 2wd.

Sport mode does put it in 4A for the advanced transfer case. The workshop manual is incorrect.

 

[Beachbum]

Mine did not. I added it using forscan because I wanted the ability to use 4A in the snow and not worry about using 4H. From what I'm reading though it looks like Slippery mode offers the same ability.

I suspect that by adding it later you may have changed it's base functionality as in going to 4A instead of staying in 2H.

Yes, that's true. But you can push the 2H button and run Sport 2H. That's the sweet spot!

Yes it does. By default.
