My Taurus SHO had this problem new from the factory.
Ford serviced it with a new TO bearing and a thin stainless steel sleeve that went over the existing.
No lube was necessary.
There was black grit involved which I believe was from the disc materials.
There is now a TO bearing that is referred to as "ceramic" but I think that is because this is a constant contact TO bearing and there was another issue with the fingers on the pressure plate wearing.
