Could be tires out of balance. Or a bad tire.

sufficiently significant to affect the whole world; as, earth-shaking proposals
It may be you are doing it standing up and his knees are shaking
You may want to check this with your dealer, but not too recently the cav and sunfire had a recall on the power steering. Something about a bad gear and power failure when making left hand turns. They would either replace the faulty gear or the whole rack and pinion assembly. Either way have it checked out. A steering problem is not a nice problem. It may cause accidents or death.
1972 caprice classic tops speed is around 115 to 120 top speed with the whole steering wheel shaking, the car can go faster considering the fact the car is pretty heavy and all so theirs your answer
Replace the whole rack, it would take speical tools to replace seals
Shaking can be caused by a number of things. Is the whole car shaking or is it more in the stearing wheel or during braking. Have the tires balanced. This is inexpencive and could be the problem also have them checked for seperation. It could be a severly worn wheel bearing. If the shaking occurs more during braking it could be a warped rotor. A worn tie rod can also cause some shaking. My best advise is take it to a tire shop first to rule that out and most shops can check the tie rods, wheel bearings and also brake rotors. Hope this can help get you started.
Have to replace the whole switch
It could be that one of your brake discs is is bent this happend to my Ford Telstar which is just a rebadged 626, if the shaking is more orientated to a corner of the car that's your problem, if the whole car shakes I have no clue sorry
I don't think so. If anything, he's copying Ultimate Warrior, with his whole rope shaking thing...
