In Need Of Help

I need help with my 3rd gen max. I've been having this problem ever since I got this car. If I align the car on a Saturday and I go to work Monday, the car is no longer aligned. Also, when I drive over 65mph you feel this tremendous shake. I've changed springs to Eibach, added new struts all around, added new rack-&-pinion, added all front end bushings, and aligned it more than 3 times in a month and still the car alignment goes away and tears up my left hand side bushing. I think I've done almost everything except changing the control arms, I even changed a motor mount and still the car does the same!!! If anyone have gone through this or have an idea, please write ASAP!

How do you know your alignment is wrong the next day?

What bushing gets torn up?

I know when the alignment goes because when I drive it in the street I need to keep the steering wheel kind of turned on one side in order to keep the car going straight and it also happens in the driveway. The bushing is the one in front of the control arm.
