front end shimmy on 2003 Chrysler Sebring

I bought this car with 52k. It has always had a shimmy in the front and the steering wheel shakes. It worn out the tires on the front outside edges. I just put on new tires and alighnment, also new axels. After I put on the new tires it was much worse and now its still bad, Help several mechanics can't find out whats wrong.

Does it shimmy when you brake? As in warped front rotors? Also, I have seen and replaced lots of steering racks on Chrysler cars because the inner tie rods go out and you have to replace the rack, this will also cause a shimmy.
