Rep Power: 0

Hello, so my mother gave me a 09 Honda Civic LX-S Sedan couple years ago for my first car. Even though I used to hate it, recently I started to really enjoy driving it and I want to learn and start to take care of it. Because I am new to cars and mechanics, I do not know what is wrong with the car. Whenever I go over 51mph, the sides of the front bumper starts to make a rattling noise. When I looked at the sides, it seems like its missing couple bolts or screws that hold the bumpers in place with the body, but I'm not quite certain. Does anyone know how to fix this issue or would it be better if I replaced the front bumper? If I do replace it, how much would it cost in general? Thanks in advance!
