Problem with the right front wheel
I have recently hit a speed bump (10-20mph) and all of the sudden I heard a big bang in the engine region. I took a look under car and was nothing unusual. Then I tried to drive the car forward but it sounded like hell :| the most accurate thing to describe the sound is like a broken bearing.
After 50 meters I pulled the car on a side of the road and when turning the wheel another bangs were coming from the front right wheel. When I looked under can I saw some ceramic kind of bits( I will try to attach a picture).
Does anyone know what can it be?
Thanks a lot in advance

edit: forgot to mention the cars is a Mercedes C220 cdi coupe from 2001
