you would hear a creaking or squeaking sound, not a clicking. To check the ball joints jack the car up by the suspension and try to move the tire back and forth, then up and down. Do the same with the truck jacked up by the frame. This will test the lower ball joints with them loaded and unloaded.
If you feel any play, look behind the wheel at the ball joints and tie rods, if you see movement, that is bad. If you feel play and the ball joint or tie rod ins't moving, it will most likely turn out to be a wheel bearing.
