Shaking

That sounds like a bad tire, they can often vibrate at a certain speed which can go away at a higher or lower speed. (Tires have steel belts in them that can go bad.) Have a shop spin balance each tire. You could also inspect each tire, look for uneven wear that might indicate an alignment issue. However a bad tire might still look perfectly fine. If the tires check out okay then have the suspension and steering components checked.

Try having your tire balanced it should correct your problem
