My 200 Bonne was VERY smooth. Took it in for a brake job (I'm no mechanic, and they started squealing) and rotors needed to be turned, too. New ceramic brakes, turned rotors, and now at about 65-75 mph the car shakes like a front wheel is slightly loose (it'* not...I checked). It was smooth before the brake job.
WHAT THE HECK could've happened during a brake job to cause the vibration?
They told me the tires were out of balance, so I took them back to the dealer and had them rotated and balanced and the vibration is still there.
Any ideas?
Thanks for your help!!

Sounds like they didnt turn the rotors true or took them down to far.
