Bronco comes to a full stop by itself

[604Bronco]

I come from a Land Cruiser which is full time 4wd and this isn't even a consideration...unless you do something stupid

Ok ok it makes perfect sense. I knew about 4H vs 4A, just didn't think about it at the time. I come from a Land Cruiser which is full time 4wd and this isn't even a consideration...unless you do something stupid like leave the lockers engaged. FWIW I've been doing this a long time, know exactly how 4wd works, low/high, locking diffs, etc. But this is an area where the Bronco works a little differently from traditional 4wd vehicles. I won't forget it again.

Does the Land cruiser not have the option to select 4H ?

With 4H you need to think of the transfer case as a center diferential. When engaged the center differential is locked sending 50% of the power to the front and rear axles.

LOL! You just can't accept that you screwed up.

Your bronco stopped because it was screaming for help.

How do you figure that? Seems to me OP definitely owned his mistake. He gets it was totally something he did that caused this. He clapped back a bit at some of those throwing shade his way, whether it was good-natured ribbing or otherwise, but he definitely owned up in my opinion.

Bite me.

Hey man I threw you a rope ladder and tied it to a tree up here but if you want to stay in the pit and keep digging with your shovel that's fine too!!

Oh I’ll admit it, definitely learned something here! And it’s fun reading all the comments. All good.

Except there are now a bunch of us that know of your error. How willing are you to buy our silence? Hmmmmmmmmmmmmm!!

After buying the Bronco, how about a party hat and a kazoo?

80 series cruisers are full time 4H with a big lever to switch to low range, and some have electronic front and rear lockers. Pretty low tech setup that works incredibly well.

I should mention that the center locker is only engaged when you either switch the transfer case to low, or you make a small mod with a switch in the dash. Normally it’s always open, which is apparently the difference with 4H on the Bronco.

As a rodent, that’s my job.

Yep I get it now, that’s a connection I hadn’t made before. But it makes perfect sense, thanks for that.

And I appreciate it! But apparently I’m not smart enough to reach for it.

This surprised me. I was in 4H leftover from the weekend camping trip, just hadn't switched it back. Normal mode, just 4H. I went to meet my wife for dinner last night, and was rolling through the parking lot, foot off the throttle. I slowed down a little and started to turn into a parking spot - no other vehicles around, so no parking sensor stuff. As I turned, it braked itself and came to an easy full stop. Not sudden, no emergency braking, it just came to a stop as I was about halfway into the spot, front wheels still turned. Parking brake was not on. I had to goose the throttle to get it to move again and get parked. Then I looked down and realized I was still in 4H, wondering if that had something to do with it?

I've experienced the emergency braking, so that wasn't it. When we got home from camping on Sunday, we washed it including the underside, and I got a Parking Brake Fault. I assume that had something to with the wash, because it didn't happen again, like when I went to dinner last night.

This could be a combination of both binding in the drive train (no differential between front and rear) and the differential braking feature of the Bronco applying brakes to the wheel that is turning faster to vector more torque to the one that is turning slower. I also experienced this when I attempted to perform a U-Turn in the road and I was mistakenly in 4H. Nothing to be concerned about, perfectly normal.

Sorry Mark, but you are not correct. The rear wheel torque vectoring is only active with trail turn assist or in the event of a high speed loss of traction and VehicleDynamicControl intervenes to prevent total loss of control. Making a U-turn with traction in 4H is always damaging to the drivetrain and is something to be concerned about.

Although I don't know all the fancy off-roading features of my Bronco and when to utilize them, understanding basic 4WD and how it works (and when it should/should not be used) should be a prerequisite for buying a vehicle like this.

You guys are way off base. Running 4WD for a short duration on pavement isn't going to hurt anything, and its easy enough to realize your error when you feel the resistance to turning. The drivetrain is plenty robust for this. Do you think there is any less strain on the drivetrain when rock crawling? That said, no you don't want to do this long term, but if it happens now and then, nothing to worry about.

Don't go 70 in 4low either
