The idling is ~750rpm in (N) and moving the stick to (D) or (R) it goes down to ~650rpm. The car jumping/moving is less notice from (N) to (R). Though, I can see a small oil leak from the differential maybe I only need to fill up the oil (and fix the oil leak)?
Or I maybe need to install the vibration damper (#124 350 06 72) 'to the rear axle center piece mount of rear axle carrier' suggested in MB Ref 41/018, date 950401? (The car has only travelled 122.000 km). P.S I have subscribed on http://www.alldatadiy.com/
