The previous poster before described it best IMO. I had the same thoughts as you until I looked it up, and read about it.Thanks to several for the responses as this has been on my mind too.
I've watched several videos about mechanically what is happening in a 4x4, AWD, etc. but have still had problems understanding some truck stuff here. (I was a car guy in the past and even swapped rears (gears, t-lok) for a Mustang so I have a general background)
I was under the impression that the base 4x4 would have front and rear t-loks or equivalent (automatic mechanical locking of both axles when slippage occurs on the powered wheels).
Please, please don't feel me that a base 4x4 only has one wheel driven in the rear and one in the front? That wouldn't be "4"x"4".
I do understand what a locker is and its use. I MAY want a rear locker but that's it. I definitely would want a t-lok or equivalent in both differentials.
All wheels would be driven - in a 4WD automobile when engaged - on a surface with equal traction. It is in fact 4WD on the base. Having said that, with an open diff; it sends more torque to the wheel with the least resistance, thus a slipping wheel would get all the power sent to it.
This was another reason I wanted to stick with the BB vs. the Base, to be able to add the rear locker. I may never need it, but it would be nice to have, just in case.
I wish Bronco had at least limited slip diffs on both axles. They could have that but from what we all know they don't.
