X5 vibrates violently
 

I'm having problems with my 2003 BMW x5 4.4 a few days ago I notice the car shaking on the highway only when turning right on curves. So I have changed both control arms upper n lower n ball joints got the car balanced after changing the car vibration got worst to where the point I can't drive it on the high way... Any ideas of what could be the problem? Warp rotors, stuck caliper ?

Bad tires, could be a bad sidewall on one of the tire. Sidewalls of a tire are loaded up more while in a turn.

If you have not thoroughly checked the rest of the suspension including the front axles and sway bar links/mounting bushings, I would do so. Even though you have done some suspension work I still lean toward cause is in the suspension. Sounds pretty bad since you can't drive it on the highway now. How many miles on the suspension?
