The noise started on Friday. There is no noise when idling. When coasting there is clicking but it is much less than when accelerating. I only have to hit the gas a little bit to get full volume clicking. Possibly when the engine torques over whenever the gas is applied causing the rotating element to bear more on what is rubbing against it. It is very immediate when I apply any amount of gas. If it were brakes it wouldn't be affected by the accelerator.
The car is relatively new to me. I haven't changed any of the axles, but the left front does look to be newer/different from the others.
