Marshall Your explanation that front propshaft comes with the vibration damper make a lot of sense in that the EPC does not list it seperately. The picture depicted on the EPC suggests that the mount may be part of the driveshaft.
It seems that my vibration is not strictly engine rpm related and am considering that it might be differential mounts .

The 124.130 with a manual transmission (the damper on automatics is quite different) was designed to have a vibration damper on the driveshaft, but some did not require one. The damper has NO effect on engine vibration but ONLY on vibration related to ground speed. I have a friend with a 124.003 with a 5 speed. When the damper collapsed (or more accurately tore apart) he had it replaced. On some cars (201s for sure) the only way the vibration damper is available is along with front half of the driveshaft. At least one member of this forum has replaced the front driveshaft to replace the damper. There are several driveshaft specialist that claim they can balance the shaft with or without the damper. Others argue that that is not always possible. Marshall -- Marshall Booth Ph.D. Ass't Prof. (ret.)
