Reinforced guibos
I have a custom driveshaft in my W124 that has u-joints only. My clutch disc is sprung, single mass flywheel. I have poly diff mounts, poly subframe mounts. The torsional vibrations that occur under certain engine speeds and loads, which are worst in top gear, are horrendous. It sounds like a big diesel truck driveline. I'm going to cut off the u-joint a the diff and weld on a big flex disc flange. Hopefully one large flex disc will be enough to keep it from rattling my teeth out. The rear is probably the best place for a flex disc to come apart anyway.
