04 Regal. What part is...?
 

If your looking at the car from under it in the rear. There are two long bars on each side connecting to the hub i believe. They have adjustments on it possibly for aligning the wheels. Again, these bars are maybe 3 feet long.

My reason for asking is that my car was in an accident and one of the bars is bent. It is not allowing me to align the wheel properly. Please help because Ive asked mechanics, people who think they are mechanics, and even looked for pictures online for the part. No one knows. WHAT IS THE NAME OF THIS PART?!?!?!

I mean if you look at a picture of the car from under it, in the rear there is 4 long bars. You cant miss them. its an 2000-2004 regal. Two cars in one.
