Yes it is normal. Im gonna try my best to exaplin why....here goes....

First of all when you make a turn, especially a tight turn, all four wheels must travel at different speeds to make the turn.

Now, 4x4 and 4wd are completely different creatures. Your car was 4wd and despite the fact that all four wheels would drive the car, there was some way (either electronic control, center differential, ect..) that the drivetrain was prevented from binding when making a turn. The car could make a turn and allow all four wheels to spin at different speeds.

With a truck, there is no way to limit wheel speed on all four tires (unless you use auto 4wd, but I'll explain that in a minute). There is a direct link from front axle to rear axle when in you put it in "4x4". So two wheels must spin at the same speed (one front and one rear) at all times to prevent binding. Well when you make a turn on dry pavement, all four wheels must spin at different speeds, but those two wheels are trying to spin at the same speed. Now you have binding which is fighting the engine and steering.

So you hit the gas harder, well you can't feel it sometimes, but one wheel is slipping on the pavement in order to complete the turn. Thats why they recommend using Auto 4wd on variable condition roads and 4x4 only when the driving surface is wet or slippery.

If your truck has Auto4wd, try using it when roads aren't consistanly slippery. What this does is engage 4wd during acceleration, then it will disengage the front axle until the wheel speed sensor detect wheel slip or until you accelerate, the it will engage again. But the cool part is when you turn, the truck will engage and disengage the front axle several times very quickly to keep your traction but prevent the front axle from binding.

Ok, that should cover it I think.
