light shimmy at 50 to 60 m0h

What is your question?

I had new front wheel bearings installed on both front wheels.new rotors and pads,and the wheels lined up.had a bad shimmy,shaking the steeringwheel at 50 to 60 mph. work done by dealer.I can still feel a very lite shimmy at 50 to 60 mph,but it isn't steady but it is really very annoying knowing the repairs that where made.Anybody know why?????or any suggestions

How long has your 2003 Cadillac CTS had this problem?
