Hi Jonathan,
I think, it´s speed is too high to make te vehicle "jerk", it would rather rattle, hum or drone.
That sounds to me like the prop shaft...

Hi Tiemo, hi forumers! Now the defect seems to appear sometimes even without accelerating… i saved on Dropbox a few videos (bad quality, sorry!) at this link:

https://www.dropbox.com/sh/l0yr9iutdmyhn2o/AABh6aLOZhTSxqQ-WphYBXJVa?dl=0

actually: fuel filter new, injectors new (not tested before installation though), valve clearance accurately set, both belt's tension ok, injection pump tested and probably ok. I say "probably" because i don't thrust much in the diesel mechanic who tested it. as soon as possible (again covid lockdown now here in italy) i'll make a compression test. ideas? Thanks!
ciao
emilio
