I have had a scuffing sound lately but didn't think much about it at first. Initially I figured drivers Front Strut bottoming out. Again that is a planned R/R item soon with the 100K phased overhaul. When I was getting underneath to place the Axle jack/SafeJack for the recent brake replacement I discovered that there is a blanket that appears to be tearing itself apart. As I was driving I was trying to tune my ear and eventually traced the sound to the blanket catching and now it is tearing itself backward. I cut a piece of it off at least the part that was the folding back part hoping to get a part number label but no luck. I am scheduling a engine/Transmission mount R/R soon and if the blanket doesn't totally tear itself away by then I will ask those mechanics to remove the blanket if nothing else to either find part number or bring into dealer for parts catalog illustration.

Blanket is between the fenders on each side running along bottom outside of frame and one on each side. I say fire blanket but my guess is more of a noise suppression and does appear to be covering the brake and fuel lines running along the lower outside of the chassis. It does appear to have some fire suppression if needed but I hope not to find out. I checked several sources but can't seem to find the specific nomenclature to find price and availability.

Any ideas? The front of the blanket appears to tuck under and inside just behind the front fender. Appears to be the same material and design as the fire blanket on the hood.

Just noise suppression...

Yes, Mud has you covered here. Those are very fragile and will tear easily. Not sure what MB was thinking with these under body panels. My 2010 were both destroyed
