4 X 4 turning motion lock

To whom it may concern,

I have a 4 X 4 Ford Bronco. When I turn the wheel either way (fully), and try to accelerate, I feel its hesitating or locking. This happens when I turn the wheel from the center to either side more than half way. Maybe even the rear wheel lifts. My apologies that my English is not so good, but I described it to the best of my ability.

Thanks in Advance

it may be your universal joint in the front going bad and are you sure the locking hub are unlock they did have trouble with those not unlocking jack up the front then rotate the tires to see if there unlocked
