Noise on front drivers side

Okay guys I have a 2011 Tacoma and I just bought it. I noticed after a short time that every time I hit a bump there's a knocking sound in the front end. But it sounds like it's in the steering wheel at the same time. It doesn't do it when I turn or anything else it's just when I hit bumps on the driver's side. Any suggestions to what it may be?

 

I have this same issue. I have a theory that it's the cover for the fuse block that's behind the battery but haven't got around to testing fixes (IE removing it temporarily).

Does it almost sound like... hollow? That's the best word I can come up with to describe the sound. I have replaced (for other reasons): UCAs, Pads/Rotors, Wheels, Shocks/Coils, the sound remains...
