Saturday I replaced my near side front bearing, then the calliper housing blots snapped I when and picked up 2 from fiat, since then the car has had a noise that only happens when you drive roughly 3 miles then below 10mph the near side starts making a grinding noise it's not consistent like it a sand paper on metal noise but it disappears at the higher speed you go, I thought it would have been the break heat shield possibly catching but had the disks off and knocked it all down but the noise is still there, any ideas of what it could be?
