2002 Ford Focus with knocking under the floorboards

noises

#1

I have a 2002 Ford Focus with about 83,000 miles on it. It is a manual transmission an has been with me since it was 15k old. Recently, I took the car to Firestone/Bridgestone to have new brakes put on. They ended up putting the front passenger brake on backwards so that a large paper clip looking thing (I, obviously, am not a car expert) kept poking out and hitting the rims. I took it back and they fixed it but now I notice a clunking noise coming from under the fllorboard on the passenger side. When I sit in the passenger seat I can actually feel it. It is most prevelant at lower speeds when I am going straight. If you have any insight I would appreciate it! Also, I am about to drive it 450 miles and am hoping the wheel doesn’t fall off, let me know if that is something to be concerned about :slight_smile:
