Any ideas where to look for a bad front end vibration. Occurs at around 60. The vibration is not really noticed in the steering wheel but through the body. I have had the wheels balanced multiple times just in case. It is especially bad when braking. As the speed drops to around 60 the vibration is so bad that the cars seems like it might shake itself apart.

Best idea is a bad bushing, but nothing is obvious. Any ideas where to start?
