I had a very similar violent shake throughout the entire car between 50 and 60 MPH. After successive parts replacement on the front-end (drive shafts, CV joints, boots, ball joints, brake discs, etc), it went away. I'm certain my problem was a bent drive-shaft. I have not had to change my wheels though. If you know of a bent wheel, then that's the first place to start. If you've got a bent rim, that would indicate some abuse which may well have transmitted to the suspension and steering setup. Paul
