there were two other strong vibrations but as somebody pointed out above, probably a suspension part with that particular resonance frequency
if it sounds like a ufo 'wuh wuh huh' very good chance the bearing. if the sound moves when you swap wheels that usually means you lost a wheel weight or dented the rim from a pothole (i've had both happen) or can be internal tire belt separation i've had that also; Z28 gets pretty shaky at 110-120 when the belts come apart on your Z-rated tire.
if a dif part vibrated at the same frequency as the tire rotation it shouldn't be too bad it would mean a boot or seal more than likely ; dif takes a shit the frequency will be high with a horrible growl sound.
