Hey when I get up to like 40 mph, my steering wheel starts to shake kinda violently pulling left and right.. feels like im fighting a flat tire sorta.. ... started on friday... but i didnt drive it until tonight.. whats the problem??

 

loose stearing box?

 

look at your tires closely. I had a problem like that. one day i was under the car and found a huge gash on the inner wall of the tire. It looked like the tire was about to pop. I replaced it and the problem went away. Also a friend of mine also had a problem like that. He bought an (agh) accord for his wife. He took it to a shop and they told him he needed to have his car realigned. He did that and the problem was still there. He took it to another shop and they told him the tires needed to be balanced. They balanced the tires and he said the problem went away.
