I've recently traced a rattle when I go over speed bumps, potholes etc to the rear offside disc guard/shield, which is now free to move back and forth, thus bouncing/rubbing against the disc when the occasion calls for it.
It appears that the top mounting screw has sheared/rusted as is now no longer supported in this area.
Is this a common fault? Also, will this mean having to remove the rear hub in order to access the mounting fastener?
