Checking flex disks - PeachParts Mercedes-Benz Forum

I'm working straight through for the next 10 days, so it will have to wait until the weekend after next to start looking at it, but here is my plan so to speak

I'm going to jack the car up and use a pry bar to check the flex discs for cracks, etc, but mainly the work is going to be 1. Drop the drive shaft as a complete whole unit and change both flex discs, 2. Change the driveshaft center bearing and the center bearing mount. 3. Change both motor mounts, 4. Change the transmission mount.

That said, I have looked at all the wiki's and how-to's and all of it looks fairly straightforward. I do have a couple questions though..... 1. Is there a good pictorial how-to on how the change the motor mounts? I have read the write up, but photos would be a big help. 2. How many transmission mounts are there? I'm assuming only the one at the rear, and is there any special things to know about changing it.

Thanks,

Glenn

Sounds like a good plan - some notes:

1) Exactly. Yes.
2) There is also a rubber 'bearing mount boot' you'll want to replace. I'll send you the extra one I have, if yours is the same as my car ('83 SD) uses.
Also, I believe you need a big circlip remover for the bearing on your car; Stretch* can verify.
3) Motor mounts (on my car) are mounted with a large hex key; be sure you're ready with tools. Issue here is simply being able to safely jack and support the engine. Otherwise not a difficult job.
4) Same is true for trans - jacking and safe support. But you'll have to do this to remove the driveshaft, anyway. Trans mount is easy to replace; standard nuts and bolts.

1a)? One thing I regret not doing on the same project was replacement of the trans output shaft seal - and perhaps replacing/tightening the yoke nut at the same time. I just wasn't prepared with parts and tools for that; a shame with everything apart.
