so listen to this..about a week ago i was on the high way and i had to decel real quick, so i hit the breaks and my steering wheel was shaking like crazy. I looked at the tires and they're wearing normal and when my steering wheel is straight, i go straight. i figured that the alignment was fine, so it had to be the rotors. i was driving today and slammed on the breaks and there was no shaking at all. the only thing i did was tighten the lugs. could that have been the problem?
