Since I'm new to a full size 4wd (biggest vehicle I've owned) My new '07 CC seems "very hard" to make a tight turning radius while in 4 high. It just seems like something doesn't "feel" right.

That being said. Am I doing any harm by trying to make a tight turn in 4 high.....? Or, is this normal?

It is supposed to be hard to turn sharp in 4wd. It won't do any harm, unless you are on hard ground, like concrete.

Are you on loose soil/mud/sand/snow or ice??? If not then you are thrashing your very expensive 4WD truck. Never turn on dry, hard surfaces like concrete or pavement, it binds up your gearing and will cause failure.

To be sure, read the 4WD section of your manual before putting it in 4WD.

Hope this helps.

On dry roads...yes. We have part time 4WD. There is no center differential so the front and rear is locked together. If used on anything other than slippery roads or dirt, you're dragging the inside tire while turning.

No! Never on dry Pavement!
Generally when I'm driving on snow covered roads in my town, NE PA. I'll kick it in 4wd... so I don't spin the rear end out while I'm turning or navigating (tight streets)...I'll go to make a hard turn and it feels like it's "binding", Like I can't make the normal radius turn that I would in 2wd. After the explaination of the center hub, I'm guessing it's a normal function of the the wheels being locked together with different turning radiuses...Just feels weird and not normal...especially cutting the corner when backing up into the driveway.

ouch... learn by doing... there was a thread that gave a link to what happens when you're turning in 4wd... in short, the path of travel between the front wheels and rear wheels are totally different and causes binding issues, which will stress the drivetrain and suspension and potentially cause damage... so 4wd on hard surfaces isn't recommended...

I guess even on snow covered roads that if you have enough traction you can still get a little binding. That's probably what you're noticing and I wouldn't worry about it.

another thing to consider is that when your drive wheels loose traction they loose torque and you go nowhere... when you are in 4wd on slippery surfaces and turn the wheel your front wheels slip (loose traction) then your back wheels plow you straight ahead thus severly lessing your truning radius.
