Yep, that's it. If your diff mounts are the same pt# as the W124 6cyl/diesel diff mounts then I'll sell you a set of poly mounts that I made. Way, way stiffer than stock. Even with those it won't be "fixed".

Right now I'm eyeing action at the motor mount end. My motor rocks around a lot in the engine bay despite having pretty fresh mounts.

With respect to flex discs, I was talking to Revshift about making some flex discs to fit the 190e stuff but they quit returning my calls e-mails. They claim to have a disc made for the '05-06 GTO that should fit the W124's. Stiffer flex discs should help too, but I think the majority of what I'm dealing with now is from the engine rocking back and forth on the mounts.

Revshift flex disc:

wow that's cool, how much do they run? I'm wondering if the cases or mounts are different on our cars. I'm guessing the 5 speed Canada cars probably shared the same case as the Auto's just different gearing so the bushings should be the same. I will try looking for a part number to match up.
For you I'm wondering why this didn't completely solve the problem if all the bushing are like new? The car didn't do this when it was new, surely there is something being overlooked?

I checked and it appears that the 201 diff bolts right up to the subframe without a mount. So you're good there:-)

Those flex discs run 130 USD, but again, they don't make one to fit the 201. They had a page on their site where they claimed to be willing to fab up custom discs, but they've removed that page from their site since I asked them to make one. Pretty weird.

Since your car was born a manual (mine wasn't) have you checked to see if that linkage damper thing a.k.a. "dashpot" is worn out? PN 6010701367 It's supposed to help prevent this issue.

I have two 240Ds, one with a dash pot and one without. The one with does shift nicer and the one w/o a little rougher but not that much difference.

Nobody else thinks it could be the springs in the clutch disc? My 79 will get to bouncing at low RPM and I have to shift down or she keeps bouncing. I thought it was the clutch disc which only has about 50k on it.

But you can order a clutch sprung or un-sprung and it doesn't make a difference once engaged..
The only thing clutch side I can think of would be IF the flywheels on these are dual mass, the bushings holding the masses together could wear out and cause a discrepancy in power being delivered almost like rubber bands.

I didn't realize the diff was a solid mount in the 201's that seems insane, and it still makes a good clunking sound getting into 5th. hmm

Considering the whole rear subframe is mounted in rubber, it doesn't seem that far fetched. The rear diff bushings I have now are very close to being hard plastic yet did not translate to much of a difference in NVH in the cabin.

Winmutt, I had a different experience with the trans mount I got from you. I was having an issue with a gusset on the trans tailhousing bumping against the crossmember when I ran over speedbumps, etc... The poly filled mount fixed that right up. Other than that, I wouldn't be able to tell it was in there.

Interesting. I really havent investigated the noise yet. That is good to know. I did use quite a bit more of the stuff on mine
