This is normal driveline bind.
On a side note, (I cant find anything to say this is fact, but here goes anywho) My Grandfather, told me in the past that International and Jeep actually put a slightly taller gear in the front axle, too stop the driveline bind we experiance. That mean's that if you had 4:10 gear's in the rear, they would install 3: 92 gear's in the front. He claimed (they claimed) that if the front was just a hair faster than the back, that the "bind" wasn't so bad as the front (which goes faster in a turn) would slightly pull the rear. My grandfather claimed it worked excellent in mud and snow........Not so great on dry surfaces. AGAIN I DON"T KNOW IF THIS IS FACT!

As I remember it they used to call it whind-up and the faster front gears would help eliminate it.

It has been my experience that this binding is normal and not a concern. BTW we are getting our first snow storm of the winter here in Stafford tonight. My wife has to work a half day at her bank so I think I should drive her in. We are only supposed to get three inches but expect a sheet of ice in the am from sleet. My wife has never driven my truck before and I don't think ice is the best condition for her to experience the torque and turbo lag. I hope the Michelins serve me well.

Thats true adam, They usually do put a slightly taller gear in the front axle of 4x4 trucks. Again, I don't know for a fact that Ford did that on our trucks. but it was a general truth on most 4x4s. The faster turning front tires helped to climb over obsticles. This difference in ratios is what cases some of the bind between front and rear in 4x4s on non-slip surfaces. And was often the reason we had to back up a few feet when we wanted to disengage the 4x4
This would also cause some scary handling if anyone ever locked it in on dry pavement. Of course the scary handling thing does come into full effect in all 4x4s when turning with it engaged.

4x4s with different ratios front to are simpily due to the front axles smaller ring having fewer teeth and you cannot match the rear ratio number mathmaticaly perfect. The difference is small-For exsample-4.09 to 4.10
