Front and Rear Flex Disc - DYI
Do some one knows where I can get DYI information for W210 front and rear flex disc?
Do you have to remove or move the tranny to reach and work on front flex disc?
Also any one can tell me how much front and real flex disc cost $$$?

as for a price on the parts, I have no idea. However, doing the job isn't hard at all. It is much easier if you have access to a lift to get the car completely off the ground, but might be able to do it if you jack it up far enough with some taller jack stands to support it.
To replace the rear is easy. I believe the original bolts that were installed with it are 19mm. I prefer to use a ratcheting wrench or socket/ratchet on one side and then an open side of a wrench for the nuts. Just put the vehicle in neutral and take all the bolts out. After you have them all off, take a pry bar and pop the rubber disc loose from the drive shaft and from the pinion flange on the rear differential. Pry the old disc out and put the new disc back in making sure to remember which direction the lettering is facing on the disc.
For the front you need the same tools, but I would recommend a jack with a small 2x4 block of wood and 16mm, 17mm, and a 13mm sockets to remove the rear transmission mount and support brace. After that use the same process as what you did for the rear flex disc and make sure to tighten everything down when reinstalling it all.
