NEED Help From all X5 gurus and gods.........Shaking Badly

[SLX5]

Ok here is the whole story
One day I got off the interstate, the vehicle started skaing as I applied the brakes. Came to a stop sign, and was driving about 45mph and the car started shaking. Stopped at a friends home and on the way back got to 45mph no shaking at all. But within the last two weeks, everytime I got to 45mph or when braking at that speed it was shaking.

I realized I had a stuck caliper. So I ended up replacing both the front calipers. I replaced both the tension bushings, and lower control arms. I didn't replace the tension arm ball joints since they were very stiff. Got an alignment done yesterday. The car drives straight, but the second I tap the brakes, the steering wheel shakes violently (Left/Right) yet my brake pedal does not pulsate at all. I replaced rotors with drilled rotors and ceramic brake pads less than 10K ago. Also chnanged the sway end links; I am completely lost and very very frustated with the damn vehicle right now. Any suggestion..........
