If it came loose, it would cause that kind of mark as it rotated around with the driveshaft. We won't talk about how I came to this theory just by looking at scratches on the bottom of your car.


PS. Are those two little screw holes, like you'd mount a bracket with, just to the right of the mark in the picture?
I don't remember seeing any holes in that area. Probably just grease specs I missed. The camera flash shows everything!
