When going around sharp turns slowly I hear and feel a banging noise in the front end. Could this be caused by worn out u joints in the front axle or do you guys think its caused by worn out u joints in the driveshaft? Or something else?

HELP!

How big are your tires?
That might sound like a stupid question, but if you have over-sized tires they could be rubbing the inner fenders on tight turns.
