I recently got into an accident with my 2001 neon. I was hit in a parking lot and my whole rear tire was pushed into the quarter. Major damage was all there, a bit on the quarter too.

I brought it to the garage to get repaired. I'm wondering what they would have changed on it? Would it be as simple as just the knuckle?

I'm thinking maybe they just put on all scrap parts because my brakes seem worse than ever, and the back is squeaking more than ever.

 

Depends what broke. No accident has the same damage as another, so it's impossible to say. Look at the list of parts the shop used to fix your car...
