A couple of days ago while driving on the highway, some retard hit their brakes hard and I had to lock up and skidded for a good 30 secs from 70mph . Now whenever I go over 45, the car rattles and shakes like no other, I figured it would either be the tie rods, ball bearings, or flat spots on the tire what do you guys think and how can I tell?

 

You flat spotted your tires.

 

It seems to happen to me within a week of getting new tires. EVERY GAWDDAMN time. But yes, you flatspotted them. depending on how bad you can try doing some heavy burnouts to round them out again, but it wont get rid of it completely.
