2006 Chevrolet Malibu Q&A

2006 Chevrolet Malibu Question: Car shakes over 45mph.

We got new brake calipers and tires changed 2-3 weeks ago. Tires have been re-balanced. It's not just steering wheel that shakes, but whole car. It was just a slight tremble, and now it's worse after balancing. Right around 45-50 it shakes, but 60 it calms down. -
