About 2 months ago, i noticed a vibration at speed and a squeaking at slow speeds going over bumps. I took the car in and they said the hydro bushings were bad and replaced both front control arms. After that it was so much quieter and smoother and felt like a new car again. I dont drive the car much, but do drive it everyday. Well, this morning at 530 i get in it to go to work, hit the freeway and when it gets to 60 it was the worst shaking and popping noise i have ever heard from any car. I mean i thought the wheel was about to come off. I pulled over and checked all the lugs and they were all tight. I decided not to go on in to work cause im scared to drive it anymore now. I made it back home and waited for a friend of mine who has a shop to open so i can put it on a lift and check it out. We start checking it out and sure enough the control arm bolt had been left loose and was just about to fall out. I know i need to go back to my dealer but im scared to drive this thing now. What do i do?
