DON'T KNOW IF THIS IS REALLY A PROBLEM..........GOT A 2000 4.7 DAKOTA, 4WD. WHEN IN 4WD MODE TIGHT TURNS (INTO PARKING SPOTS, DRIVEWAYS, ETC.) OR WHEN IN REVERSE, THE TRUCK DOESN'T WANT TO GO UNLESS I PUNCH THE GAS AND FORCE THE WHEELS TO GET MOVIN'. NOW I'M NOT TOO FAMILIAR WITH 4WD VEHICLES.....BUT I DON'T THINK THIS IS NORMAL. OTHERWISE THE TRUCK WORKS LIKE A CHARM. THANKS FOR THE HELP.

I have a 4wd, and when you turn, i think it puts extra pressure on your system (turning is what beats it up)...
I have the same problem. i dont have to punch, it, i just have to give it more gas than normally...
I think what your felling is normal... anyone else know?
my understanding is that this occurs cause you force all the wheels to turn at the same rate and they dont want to since your turning...

Hopefully you don't have a part time system engaged on a dry surface. Things will wear excessively and maybe break. Such systems should only be used under low traction conditions. Among other things front tires are rotating slightly faster than rear plus when turning front and rear are travelling different distances on the curve. There is an All Wheel Drive full time system available for that use.
Talk to some experienced 4X4 folks if you have other questions.

i plan on using it this winter alot (now that i live in New Hapshire).
But whats withe the "part time 4wd" light. ive never seen that.

Ok I had the same question when I first bought my truck.. the reason that it feels like its not wanting to turn is because all the tires are trying to move at the same speed and when you turn they can't because the inside wheels need to turn slower then the outside ones. You don't notice it when your on the dirt because in that case the dirt gives and not the tires. Basically it's supost to do that. Use 2 wheel drive unless you need to go into 4x4. The only time I use 4x4 now is when I'm going thew mud holes and actually most of them I got threw in 4x2 .. some I got stuck in the middle switched to 4x4 low and then drove out. If your going to try something stupid like that though make sure someone is with you and you have tow straps and know how to use them ;-).

Don't use 4wd on dry pavement unless you want to buy new parts for your driveline. When turning in 4wd the front outside wheel needs to slip which is what it does in dirt, snow, mud, etc... If you drive in 4wd on dry pavement what you are feeling is the binding of the drivetrain. Granted nothing may happen but there is a huge possibility of blowing a part out. It just puts extra stess on parts that doesn't need to be there. Going straight, now problem. Just don't corner or turn in 4wd unless the situation calls for it ie. daily romps in the local mud hole!

You can use 4 HIT on snowy and icy roads. When it gets to dry or wet pavement do not use 4 wheel drive. The manual state do not go over 55 in 4 HI but I never go over 35. If I am on a road that requires 4 HI I should not be going over 25 in the first place. And Dave 4 HI does not help you stop in cold weather.
I head the funnest thing last winter with a dj here in Utah. The person said she slid right through a light with 4x4 engaged. HELLO 4x4 vehicles are heavier. Harder to stop. And 4x4 does not have any extra breaking power to your rotors or drums.

The way I know when to go into 4wheel .. If I'm going off a paved road or of I'm driving ON snow.. If I'm on pavement and there is snow all around me I'll stay in 4x2. Honistly .. I've never used 4x4 Hi. Because if I'm going off road .. the faster you go the easier it is to break things. ;-) 4x4 Low keeps me slow enough to actually see where I'm driving and realize what the ____ I'm getting my self into.

Actually doch80 I drove in the worst blizard in my life in Texas. I was moving my sister from Tenn. over Thanksgiving of '97. We drove through the Texas pan handle and there was ice under what seemed like foot to foot 1/2 snow. Evrybody was sliding everywhere. Was going to stop in Amorilo but it was cleared in Amorilo so we went on. Stoped in a small town a few miles outside of Amorilo. I know this is not the norm but my only impression of Texas is SNOW. It was one of those centry storms or something.

There are 2 transfer cases. One is 4wd part time and the other is 4wd full time (option). The 4wd part time locks the front and rear solid so it doesn't like sharp turns. However I have shifted in and out of 4wd hi at 70 mph no problem and with a 5.2 4x4 RC LSD it tends to get squirrelly in 2wd on slick roads so I would just go into 4wd part time when the conditions were not optimal so the rearend would stay behind me! On the 4wd full time there is a clutch type device in the transfer case that slips so the front and rear is not locked solid and can be used in any conditions. Hope this helped. By the way this was on my 99, I don't really care for the switch on my 01. On the 99 when I reached down I knew it was in 4wd on the 01 only the little light tells me I am (supposedly) in 4wd.

Not true. The 4WD light is lit by the computer _after_ it has sensed that the shift solenoid has actually moved and activated 4WD. If the light says 4WD then you are in 4WD. If the shift doesn't work corrcetly for any reason then the 4WD lamp will not light (I think it will flash to tell you something is wrong).
A miracle of electronics...

Rowdy, that light is for the people that bought the full time transfer case. It isn't really full time 4 wheel drive but all wheel drive. If the option was not purchased then you have a part time transfer case.

The reason the front end hops when turning in 4WD is because the two front tires rotate at exactly the same speed. The differential locks and there is zero slip (essentially it is the same as posi-traction).
When turning, the radius of the inside tire is much shorter than the outside tire and does not require as much rotation as the outside tire. The hopping or binding is the inside tire trying to rotate as fast as the outside tire. This is good in snow and mud but bad on high-traction surfaces.

question? if the part time trans case is supposed tolock the front tires than why did i get stuck and a friend said that only 1 front and 1 back tire was spinning. i know only one back tire is supposed to (limited slp) but i pretty sure what you said is wrong. all tires prefer to pull in a straight line (going forward) thats why after you turn a corner the truck will almost actually straighten it self out. that is why it is hard to turn at slow speeds your tire(s) are trying to pull you straight and you are forcing them to go in a direction they do not want ot go. this problems is not appearant at higher speeds due to the speed at which the tire is rotating. think of trying to turn a auto w/out power steering when your at a dead stop. this problem quickly goes away when you traveling at any speed. the faster you go the easier it is to steer. now to the problem about the part time vs full time. they are right about there being clutches in it but they are in the fromt diff not the x-case. these clutches enguage and disenguage the front tires as nessary to ensue maximum traction and ease of steering. the x-case with the parttime option is the np231 odds are thats the one you have unless you special orderd your dak with out it. the parttime option is the x-case that allows for the best preformance off road this has been a factory part on jeep (grand cherokee) for many many years. so part time good JUST NOT ON PAVEMENT . full time good on pavement. sorry it was so long and boring just had to tell ya what i was thinking

I've got the full time transfer case and I think it's fantastic.
Here's my stab at answering your questions; I'm sure others will have something to say as well.
With open diffs in front, center, and rear the truck splits the torque approximately equally to all four wheels as long as all have approximately equal traction and you are driving in a straight line. When you turn, the diffs allow each wheel to turn at a different speed (each wheel describes a different arc through a curve). As long as you still have approximately equal traction at each corner, each wheel will still be getting about the same amount of torque.
So that mostly describes driving on dry pavement. Here's what happens when things get slippery:
Let's say you are sitting on a level sheet of ice. All four wheels still have approximately equal traction but the total amount of traction available is greatly reduced. If you have good tires, a lightly loaded truck, a gentle foot and, a little bit of grip on the ice you might be able to drive out without spinning a tire. But if the total amount of traction available to all four tires adds up to less than that required to move the truck the tires will spin and you will go nowhere.
The configuration of your truck will determine which wheels spin:
If you have three open diffs the available torque will go to the single wheel with the least traction and it will spin.
If you lock the center diff the truck will split the available torque between the front and rear axles. Each axle will send approximately half the total available torque to its wheel with the least traction and you'll spin one front and one rear wheel.
If you have a locked center diff and rear limited slip the rear axle will try to turn both rear wheels until one of them breaks loose. Then it will send all its available torque to that wheel and you will spin one front and one rear.
That's what happens when there is not enough total available traction to move the truck.
Locking and limited slip diffs help you when there is poor traction but still enough total to move the truck. They split the available torque up to try to match it with the available traction. If you lock the center diff the torque gets split about evenly front to rear. If that is enough to move the truck without spinning a wheel you can drive out. If not, you spin two wheels and get stuck.
If you lock the center diff and have rear limited slip, the available torque gets sent to three wheels. If the total traction available at those three wheels is enough to move the truck you drive out.
None of this means the torque is always sent to a particular wheel. Torque goes to each wheel in about the same amount until any wheel begins to slip. That's when you need locking or limited-slip diffs.
It's complicated and easy to misunderstand. But if you learn it you can drive past the guys who don't bother to understand it. You can even pull their trucks out of the mud.
