This past month while driving between 65-80 mph my car started to shake randomly...the wheel, passenger and driver side seats too. I thought it might be the highway cause it starts and stops randomly.

It feels like it's way more than an alignment or my shitty toyo's...what should I look for or ask to get checked?

This sucks, it feels $$$$.
