    After 8 hours of replacing the shocks, struts and sway bae links I took my 2007 on a test drive and there was this grinding noise coming from the front right side around the rotor. It happens after exceeding 10 MPH. We thought it might be the dust shield for the rotor but after bending it to where we thought would be good it seemed to make the noise a little worse. Do you guys have any recommendations?

    8 hours???

    There probably is something loose, like a hub cap. Doesn’t really sound like brakes rubbing, did you lube the caliper pins?

    What happens if you jack it up and take it for a spin?

    Like said above jacket up have somebody sit in it hold it above 10 mph obviously make sure your jack is positioned right so it doesn't fall in the car take off and don't stand in front of it stand to the side of it where your partner in the car can see you You can still be by the wheel and looking if the car teeter side to side and falls down it's going to shoot straight and hopefully your buddy will hit the brakes and the jack doesn't go through something important. Really not that big of a deal You're looking to see if the noise is happening when your front suspension and wheels are unloaded basically no weight.

    yes it does happen. I’m almost certain it’s the dust shield around the rotor. I’ve tried bending it but it just seemed it make the noise worse so I’m gonna keep tinkering with it

    I figured you would do that with the wheel off then you can actually kind of get your head in there and see or your long screwdriver and handle to listen touching things but that sounds like the backing plate You did not put hubs on this car correct or wheel bearings? So you just need to tweak that You should also with a flashlight be able to see silver on the backing plate in the spot where the rotor or whatever is touching It should leave a silver mark go to that silver mark and bend it back in towards the strut or the center of the car and I'll rotate the hub again it stopped perfect.
