Welcome!
With the R/T edition it's in AWD all the time unless you select LOW or HI.
With the AWD in your R/T the ABS system should already take power and place it from the wheels that slip to the wheels that grip.
I wounder in your situation if the 4X4 isn't engaging. On your rig the front can move different rpm's as the rear and this can make you "fishtail" although the PCM should transfer power.
first, take your foot off the gas!
second, if you stop and engage the 4 LOW do you go into a low gear ratio?
third, the position sensor on the transfer case could be bad. Not sure if it is in the accuator on that model.

I have a 2000 R/T and it doesn't have AWD, it has 4WD(fulltime).
Also when going into 4LOW, the manual says that you should be slightly rolling(less than 5MPH) and the tranny in neutral.

The tranfer case says that but you have AWD when it is in 4WD. That was standered for the R/T. AWD allows the front to rear differentials to move at different revolutions therefore removing potential axel bind. (note that you do not have 2 HI)
4 Low is for locked differentials to transfer case in LOW gear.
4 Hi is for locked differentials to transfer case in HI gear.

Wow... The confusion and misinformation...
It's true that inside and outside tires spin at different rates in turns...
but, does any transfer case actually drive the front wheels at a different ratio than the rear? I find that hard to believe.
My wifes 2003 SLT has 2WD,4HI,nuetral, and 4LO on a dash mounted ****.
She traded a 97 Grand Cherokee for this, which had a lever on the floor.
Her Jeep had a fulltime 4WD setting, that she used most often on snow covered roads. Turned corners and everything just fine. She could even pull into a parking spot in a snow covered lot no problem.
She commented that her Durango when in 4HI didn't want to turn into a parking spot in the same snow covered lot.
Having not even thought about that when we bought it, I figured it was a less sophisticated 4WD system on the Durangos. I told her that she needed to put it into 2WD to make sharp turns and manuever, even in snow. She didn't like that.
It is definately not as nice a system as her Jeep was.
So in 2003, was a fulltime 4WD available as an option? She really doesn't like this 4WD setup. It's more old-school like my 91 Bronco's system.

You are the confused here. The front does not move at different revolutions that the rear unless turning. Once you turn the wheel and drive forward then the front revolves more times than the rear tires. HELLO!
THis is where axel bind can start IF the t-case is locked in.Now the transfer cases have the ability to put more POWER to the front and less to the rear. A viscous coupler does alow for different revolutions between the front and rear axels.
You need to read this thread from front to back to understand where this is going and not just jump in. Now as you turn yes the inside tire turns slower than the outside wheels. This is made up in the differentials and not the transfer case. The transfer case takes the bind out of the front and rear gearing when the drivelines revolve at different revolutions. The diff's can't do that! They can only take the revolutions out between the wheels on that axel which are two. If the front moves at different revolutions than the rear axels then this again falls on the transfer case.
Have you ever had 4 LOW locked in and tried to turn the wheel on dry asphalt?????? This is why you get wheel hop. It isn't the differentials taking all the abuse it's the transfer case not alowing the axel to spin at different revolutions which equils wheel hop. THe wheels hop to foceably remove axel bind and all that bind is in the T-case.
Now are we clear yet!

I cant leave for one day without people catching on fire, do i have to break out the windex and help clear it up? I mean heck, its the moons alignment and the gravity that makes the differential operate, not to mention the effect the womens menstrual cycle has on the operation of the transfer case..

I forgot all about the menstrual cycle have to do with the transfer case!!!

Technically correct. Actually correct as well.
All references to FT4x4 on the 2000 D call it "Full Time". AWD was not referenced on the Durango until 2001 regardless of how it is implemented.
The 2000 is FT4x4 be it a properly equipped SLT+ like mine or all 2000 R/Ts. Applies to 2000 only.
AWD did change a tiny bit of things with it's introduction on the D in 2001. Thus technically, one could argue AWD on a 2000 is not even technically correct. From form, function and result, we will call it the same, just correct or verify both above statements: the 2000 D R/T had FT4x4 only. No 2x4 AT ALL and no AWD.

Good observation Indy! Do you have any technical info to add?
I would assume then the 2000 FT4X4 was a cross over to AWD but I guess I don't understand because the ABS senors were incorporated on the wheels in 2000?
