MB W114 230/6 model year 1974
I know the reason-it is the rubber "silentbloc"in the prop support that is perished.It is a rubber donut surrounding the bearing through which the shaft runs.
The support is available,the bearing is available but the rubber is no longer available ANYWHERE.
I have found a very useful contact in the UK who works at GKN-major transmission suppliers.He is adapting or making one for me-very helpful chap
dave.leese@gkn.com.
The firm can supply virtually any parts relating to propshafts,on any vehicle.
Hope this helps someone
