Back in action all buttoned up. As applicable to my 2004 Coupe six speed manual transmission, here are the two things I know for sure.
1) CORRECT Dorman part number for flex disc is 935-104 C $88. (Replaces MB 210 411 04 15 MB dealer price C $135+tax) Do NOT use Dorman 935-403
2) Both front and rear flex discs are identical and have the protruded bushings that fit into the yokes, 3 opposing on each side.
I would hate to have to do this job with just jack stands, I guess it could be done but not at my age!
Installed carrier bearing as well no problem. Absolutely no movement or play on the driveshaft now. Have to wait for a cold sunny day to test drive.
No warning lights, Locks working, no bad bulbs, water pump, transmission mount, gee I think I'm done!
