Re: car starts shakeing or vibrating once you hit 40 mph
There may be snow and ice packed in the inside of wheels. I would remove all wheels and clean the insides Or you may choose to have a tire shop do this and balance them. May have also lost some wheel weights.

Could be a wheel, tire, or axle shaft. You could rotate the tires front to back and see if the vibration moves. If it does the problem is one of the tires or wheels. If it stays in the front, its probably one of the axle shafts. It could also be a hub bearing or something loose in the suspension. But a loose suspension part would normally show up when you hit a bump rather than on a smooth road.
Could be alignment struts or tires. If it pulls to one side and your front tires are warn on the inside more then its most likely alignment. If your tire pressure is low that could also be the reason. If you hear a "clunk" sound or a knock when you are driving over bumps its your struts. I would check your tire pressure first. Tires usually are supposed to be at 38-40 psi for most cars and midsize suv's and trucks. Also using a different tires ( one or more different types or brands on the same vehicle) can cause this as well. And always make sure they are all at the same air pressure and none of your balancing weights have come off.
You either have a bad CV joint, probably an outside CV joint or a tire out of balance. There is a slim possibility the problem is a ball joint, bushing or bearing if you have done 4 wheeling or cross country driving or hit a few pot holes hard but start by having the tires balanced then look at the CV Joints and then the rest.
Vibration from about 40-60 mph is usually attributed to wheel balancing, but the onset when you hit a bump seems to indicate play in the steering linkages (tie rods etc) or suspension members and stabiliser bar rubbers but you had that all checked out, that brings us back to the wheel balancing.
your wheels more than likely needs to be balanced one or more are out of round if you had the tires rotated before the alignment this would make the vibrating more noticible.but balancing should solve your problem.
I have this same car with exactly the same problem. Begins shaking at 40mph and stops shaking as soon as you let off the gas, but then begins again as soon as you press on the gas and smooths out as you get over 50. And the shaking is not felt through the steering wheel. Solution: Replace the transmission mounts. There are two of them, one on each side mounted on the frame right next to the shock strut. There is also a front and rear engine mount, but I replaced the two as described and shaking is gone.
Get your tires checked out, you may have a seperated tire, or may need to get the balanced checked. and check your air pressure. then while your at the shop get your suspension checked out. while its up in the air.
