I can't wait to find out what happens next, it's like a mystery novel! Will the Benz make it? Will the elderly gentleman drive it off into the sunset? What part will fall off next?

BTW, the 123 definately does have rear wheel bearings. Servicing them ain't a side-of-the-road type of project, however. Lots of special tools, and it may require a hydraulic press; I forget the particulars. I'm don't recall ever hearing of a 123 rear bearing failing anyway. Oh, is yours the first?
