Well to start i had a cover on the under neath the car that came loose and scrubed the flooor making a racket, so i removed it and binned it till i get a new one

However i still get a scrubbing sound when going over speed bumps at about 20mph iv had a look and cannot see anything loose however on the "retainer cup" (not sure of name, where the spring sits on the front) it appears that it has rubbed there (can see clean patch in mud) seems to drive fine other wise is this anything to worry about?

Sorry for the essay
