Can anyone advise how the thin circular metal "flashing" or "shield" that is attached to the inner side of the wheel and brake disc actually "attaches" to the housing of the wheel. I posted a question a while back about a "scraping" sound on a 45 degree or greater right turn. I checked tire size, wheel well, and other parts attached to the wheel with no luck identifying the sound. But when the weather changed (got slightly warmer) I was able to identify this circular piece of metal is slightly loose by simply feeling around the underside / backside of the wheel. I know this is the source because it makes the exact same scraping sound (pitch and volume) when you wiggle it against the inner piece of the wheel / disc. The other side (right side) piece is slightly flexible but not loose such that it is scraping. It does not seem to have a significant substantive function, maybe it is a shield to keep things from bouncing into the wheel breaks from the inside underneath / or maybe a heat shield for the brake disc of some sort, but it is "loose" such that it is the source of scraping against the wheel / wheel well on turns.

Unfortunately, unlike my '92 300E 4matic the "ground clearance" on this 4Matic is much less with the sport molding, so I cannot get under the car as easily and will have to jack it up. Before I do so, I'd like to know if this is a part that can be attached / reattached with ordinary fasteners or is it a rivet / welding job. If it is the latter, I probably won't DIY. Thanks, CT
