Hello guys. I've done some searching myself but wasn't able to find an actual how-to on how to do the flex discs on an '84 W123 300D.

Before I start the job, I of course first need all the parts and tools. Could someone help me out and let me know what I need to get?

First off, I need the Flex Discs. I will order those from this website. I believe I also need a big 47mm wrench, which can be had online for not too much money.

I saw that people advise to also change the 'carrier bearing'. What parts do I need for that? On this website I can find four parts for the drive shaft:

They are the driveshaft center support, the driveshaft bearing and the drive shaft bushing. Do I need to get all three?

Other then the drive shaft center support, are there any other parts I should get?

Tips, hints and advice are more then welcome. I've never done this job before.
Thanks to advice I got on this forum I've decided to do the job with the car on ramps, and to just jack up one rear wheel to be able to spin the drive shaft.
