Fellow W123-ers
I backed off the Nylock nuts on my new engine lurch-restraint struts, as
recommended.
Et voilà! Less harsh vibration but once again I have that delightful,
urgent, diesel-engine tremble. Love it.
Best of all, the tail-pipe vibration at idle seems to have moderated
significa
Check your glow plugs -- rough idle on start is often a weak or
shorted one not pre-heating one cylinder. Shakes terribly until all
of them fire.
Also check (and probably replace) the transmission mount -- if it's
soft, it will allow the rear of the transmission to vibrate up and down.
