My car shakes when I drive
My car was doing same thing, especially between 50-60mph. My front tires were worn, switched front tires to rear... problem solved.
My car used to shake as well. What we did is got the actual Shoxx changed and then my car got fixed. It could be a number of things, get it checked.
If it's in the steering wheel could be alinement or if it's when braking it's rotators
Check the tires and make sure they ain't getting bold, if so you need new tires..
Busted belt in tires, but if happens when braking it is in the brake system .
