Why does my car feel like it's shaking?

I'm just wondering is it a wheel alignment that I might need? Its a Ford fusion 2011 . It feels sort of like it's shaking especially when ingot 60-70 mph on the express way. It just recently started feeling this way this past week.

Have the front wheels balanced. That's the usual cause.

It means you should go get your tires checked out for the wear on the tire and get them rebalanced

That's an earthquake

Get ALL the wheels balanced.

YEP, sounds like wheel alignment to me. Specially with it being at certain speeds!

You may have lost a wheel weight. Get your tires balanced and rotate them if needed.
It takes a good thousand miles of driving to wear a tire enough to cause vibration and shaking so if it happened suddenly it's more likely a wheel weight issue.

Strut bad, wheel weight came off, tier has a bubble in it, alignment is out, bent steering arm, loose nut behind the wheel any and all could cause this problem.

Get the wheels balanced bro. Hey! That don't mean its the problemo.
