it could be a bunch of things. bad wheel bearing(s), a cracked or misaligned bearing race(s), bad balljoint(s), bad tie rod link end(s), loose bolts or nuts, loose hub nut...the list could go on & on. i've even seen a warped brake rotor do that even if the pedal wasn't depressed. also a cracked caliper piston could do that. hell even an out of balance wheel...
i'd jack it up & shake the wheel & look for loose hardware &/or defective parts.
hopefully you get someone else that will chime in that's seen this before to this degree. although i've seen all of the above cause front end vibration, i've never seen or heard of any of them shaking the vehicle THAT violently! good luck man & BE SAFE!
