I am well aware of Febi and Meyle, I have spent 10 years selling auto parts. I was surprised to find that Meyle was OEM supplier to Mercedes for these mounts (evidence is on ebay right now, really old stock). Lemforder doesn't make these parts, never that I can tell. I would just like to know what the differences are, I will likely just order OEM HD in the end to have a quality bushing (we are talking once a lifetime here!) the parts catalogue mentions heavy duty in the notes for the 02 75 number, but I don't have access to know if it fits. I am going to a dealer next week with my kid mover for service, will ask what they know.
