Replace all tire withe Continentals form Luke (Tirerack) an everything disappears.
It drives like a dream. No comparison with any other w124. Checked all the arms in the back and surprise!!!! they all new with MB blue and white label attached.
Don't get me wrong but my figure is that the previous owner tried to cure the vibration but he did not think at the tires. The tires on the car were Khumo S rated, if you can believe that and there were pretty new.
