Traction control question
I think the confusion is in the term "traction control" The traction control feature consists of engine power reduction, in conjunction with braking the spinning wheel (one wheel spin control). When they say "traction control" is disabled, they're referring to the engine power reduction, not the one wheel spin control. If you shut the traction control off, it still applies the brakes to the spinning wheel, but lets you have full engine power.
Not sure why the OP's truck was pulsing the front ABS in 2wd, unless something is malfunctioning. Was the "sliding car" light on? If not, you got me there.
I was told, and I confirmed for myself, that no matter whether Advancetrac is on or off, you can't disable the one wheel spin control. (why would you want to anyway?) Even before I installed the Truetrac, I could shut Advancetrac completely off, and still wasn't unable to spin just one tire before the ABS kicked in, and got the other one spinning. With advancetrac off, my truck would leave 2 black strips on pavement. The passenger side tire would start first, and about a foot later, the drivers side started. I also tried that test on youtube for myself, and got the same results. (in snow though, not stones and rocks!)

That's the part I don't understand. The sliding car symbol was on indicating the system was off. The rear was spinning but it applied the front brakes.

Confused as hell. The only time the front brakes should pulse in 2wd is if the RSC or ESC kicks in to keep the vehicle straight. If the Advancetrac is off, (RSC/ESC disabled) and it still does that, I'd take it to the dealer and have it checked.

I haven't had time to get to the dealership yet which is why I asked on here. I actually had the service manager in the truck a few weeks ago when it did it and asked him about it. He said he check another truck on the lot to see it that one did the same thing. Up until last week we haven't had anymore snow so I forgot about it. Guessing he did too. He came from a Toyota dealership so he's still learning about Fords. I'm going to try to go in Monday since it'll be the first chance I have.

A truetrac with TCS is an awesome system. I was planning on putting one in the front and rear of my Jeep and letting the TCS take care of the traction loss issue you hear about people having with the Truetracs, IE one wheel in the air, etc. I'm surprised to hear that the truetrac allows one wheel to spin in your situation though. I though they were instantaneous since its a mechanical limited slip
No,my truck doesn't spin one tire anymore. (ever!). I performed these tests before the Truetrac was installed. I've only had this truck about 1 1/2 months. And yes, the truetrac makes it so that the traction control/one wheel spin control doesn't have to do hardly anything, except in the "tire off the ground" scenario. It takes care of the slipping tire and transfers torque before the truck even knows it's slipping. I love it.
Excuse my ignorance ,is truetrac mechanical diff set up , clutches that lock unlock on their own ? Mechanical version of electronic diff lock.
I have 3.73 and rear posi ; part time 4x4 set up.
