Thats normal with the 4x4. The front and rear differentials are locked together via the transfer case. When you turn, one wheel needs to move faster than the other one. What you are feeling when you turn like that is torque bind. The axle/wheel loads up and then slips. You should only use 4wd in low traction situations such as snow, rain, mud or off-road. Some bind is normal and fine, however you can't turn as sharply in 4wd as you would in 2wd.

As far as the heat gauge, which sensor did you check? Have you metered it out with a DVOM?

There are 2 sensors, the ECT and the gauge sender. The ECT is under the throttle body and has 2 wires. The gauge sender is located behind the thermostat neck and has 1 wire on it.

Nope, the ECT is only for the computer. You'll need to check it with a dvom. The other thing you can do is ground the lead that connects to it and see if the temp gauge moves at all.
