Whenever I drive the steering wheel shakes (or virbate) to left and right really quickly. This occurrs more violently when I drive over bumps. I also noticed my alignment is not balanced. My cars moves to the left if I release the steering wheel.

I did a search and found similar problems. Could it be the tires or the suspension?

 

Well if you know your alignment is off, go get a wheel alignment first and then see if the problem still persists. When I changed my suspension, my alignment was way off and my steering wheel was all over the place.

 

If it's moving back and forth slightly at slow speeds, you could have a defective tire, bend rim or bent hub.
