I had a similar problem once and it had something to do with my brakes, I'd get them checked if i were you

Tires need balancing?
Warped brake rotors will cause pulsation (or vibrations at high speeds) when the brakes are applied. This may also go on to misalign the calipers and cause other vibration related damages.
These are only two of many possible causes.
Bad mount on the steers, worn/loose/damaged steering components, axles out of alignment.
well... there are many different causes for vibrations. The most common cause for steering wheel vibration at high speed is poor wheel alignment.
Having a bad rod bearing could cause a truck to make a loud knocking noise and shake when driving at high speeds. The engine having a coolant leak or an engine timing problem could also cause the knocking noise.
The vibrations of the throat cause friction and damage cells.
Check the high speed relay and check connections at the switch for high resistance melt down.
No, slow vibrations make a low pitch. Fast vibrations make high pitches.
Yes it will.
Warped rotors is the most common cause.
