Carrier/rack problems of the 2009 Mercedes Benz C350

Hi, on my commute home from work, I was getting ready to exit the highway by decelerating. My car swerved and almost lost control when I began to press the brakes. There were no cars at 7am on the weekend, so I was able to coast to the light at the end of the 1/4 mile exit ramp. I continue home, but feel the car kicking out the rear end when I brake. At significantly lower speeds I look in the mirror as I brake and notice my rear right wheel turning inwards. I get home and when I wake up I lifted the car and checked to see what it was. The safety issue is that the rear bracket welded to the cross member that holds the rear tie rod craked.
