Our 2008 Mercedes S550 4Matic has broken it front driveshaft U-joint. I have been able to find all the parts I need, and have run into one problem. There is a somewhat mangled “tin cup” of a heat shield, which encases the u-joint, that has been broken off its brackets. I cannot find its part number or name. If anyone could help identifying that part, it would be extremely helpful. It is not the manifold or exhaust heat shield. Those are bolted into the undercarriage to insulate the car from the exhaust system. Rather this part is a dome shaped thin, metal housing/heat-shield that floats above and around the u-joint, secured by two thin brackets.
