Eh recently getting back from a 1600 mile trip with the 99 Saab 9-5...During the Mist of everything on the long drive that Dust/Heat shield thats behind the Rotor is Bouncing all around its loose.A bolt must of fell out of it..I can't seem to find any holes in it tho Or how to keep this Thing from Bouncing around...Sounds like my Front wheels gonna fall off its just getting annoying and nerve racking now..Anyone else have this problem? where does the screw go..Maybe a size?
