Where to start indeed. First you need to put the QR on properly (this may solve your problem or not). First take a look at the lever; that is exactly backwards and may result in a failure of the front wheel. The lever should be pointing the other way. It is not a lever that you use to completely tighten the QR, it works with a cam that is part of the lever. The correct way to use the QR is to tighten it with the lever in it's current position and them flip the lever over so the end is pointing down, not up. If when you flip the lever and the QR doesn't tighten then you need to tighten it more before you flip the lever; if can not flip the lever, then the QR is too tight and needs to be unscrewed a little and then try again. Also make sure the end of the lever that's attached is squarely in the concave end in which it sits; . Now, unscrew the non-lever side and remove the QR. Now clean the QR, the shaft, the ends of the hub and the drop outs of the fork. Now look at the position of the two springs. The springs should have the wide part on the outside, with the thin part pointing toward the hub. Once you have it set up the way, tighten the QR as I previously explained. Once it is tight, turn the bike over, loosen the QR lever and make sure the hub is sitting all the way in the fork dropouts; doing this properly should stop your QR from unscrewing and may end the binding. I'm not going to discuss the axle and bearings right now, but be advised that the use of WD-40 was pretty much the worse substance you could have used. When you done take a photo (there is no point to a video unless you say tried to spin the wheel) and tell us what it is doing now..
