Q&A

Last night I was driving and hit a pot hole or a bump, when I went to brake my car was wobbling a little bit after that it did okay when i was leaving my house today it made a cranking noise when i turned the wheel then made a weird cranking noise and stopped moving i shut the car off then turned it back on and the same thing happened, I put it in reverse and pulled it back in my spot luckily i was on a hill so it rolled back into place i shut my car off and popped the hood, then the car by itself started rolling backwards luckily i hopped in the drivers seat and pulled the emergency brake in toime befpre it hit my dads truck, does anybody have any ideas as to what it is?
