One-Wheel-Drive on road concerns

[SupremoSombrero]

I just drove an Explorer (boring) - and I kept spinning the inside rear wheel while accelerating out of corners. And then engine power gets cut...no fun.

I’ve spec’d a standard transmission with the 4.27 locking rear diff; but that’s only for rare off-road use.

Does the Advanced 4x4 allow us to run in basically ‘All-Wheel-Drive’ on the road? If so, I’m definitely upgrading my build.

No.

 

[Corsair]

Yes.

 

[ZackDanger]

Maybe.

 

[Drunken Wisdom (END)]

Maybe

Edit: yep I can admit it... 2nd is the 1st loser.. I tried.

 

[Lab00Rat]

Perhaps.

No. It is 4wd.

That post might just be my crowning B6G achievement.

You have 4A then for road use.

You do realize it's not supposed to be a sports car... right?

Isn't it good to be first?

I’m going to have a problem forgetting that it’s a truck. I’ll have a GT500 to fall back on.

Looks like I can’t get the Advanced 4x4 u less I get sassy; so I guess I’ll just smile and enjoy the tire smoke (with ESC defeated.

To honestly answer the OP’s question:

4A is just the ability for the Bronco to stay in 2H and “instantaneously” transfer torque to the front wheels by engaging 4H when slip is detected (without you having to reach down and engage 4H)... all while allowing some slippage between axles thanks to a clutch pack. This means you can leave it in 4H on otherwise high traction surfaces without fear of drivetrain binding.

What you’re describing in the Explorer is the symptoms of an open differential, which all Bronco’s have. In an open diff torque follows the path of least resistance, so if one will is free to spin, the motor will just spin that one wheel.

What *should* happen (in modern cars including the Bronco) is the vehicle will apply brake force to the wheel that’s spinning, effectively transferring torque back to the opposite wheel on the same axle. This has the effect of mimicking a limited slip differential. (If the effort to spin the slipping wheel is greater than to turn the wheel that’s propelling the vehicle, you’ll start moving again from the wheel with the traction)

The down side is you’re technically losing some power to heat on the side that’s being braked... but from the driver’s seat you shouldn’t be left stranded, and assuming it’s a temporary slippery patch, you’ll be right back on your way without drama.

When the vehicle starts to cut engine power all together, that’s when things are getting really complicated. More complicated than my whiskey brain can address right now.

Badlands non SAS had advanced 4x4
