I forgot to mention that you are missing my
argument...my point is not that sachs clutches are the
problem, but that there is a syncro specific clutch
with a separate part number, and while some syncro
owners have used the 2wd sachs clutch (supposedly good
for the syncro, too, according to sachs) without
problem, other syncro owners have had problems with the
2wd sachs that went away once they switched to the vw
specified syncro clutch with a separate part number.

this may just coincide with that period of time when
tons of people were having trouble with the sachs
clutches chattering....and some distributors reportedly
rejected large shipments of them deeming them
defective...and i was told by one local shop that they
would not warrant a sachs against chattering.

i also know of one syncro owner who attributes
catestrophic clutch failure to use of the weaker 2wd
clutch.

i'm just trying to save people the same head and heart
aches i went through...and added expense...when i
installed a 2wd sachs clutch in my syncro...and had to
pull it out.  Was it because it was not the syncro
clutch, or was it one of the defective sachs clutches?
who knows, but the vw specified syncro part number
cured the problem.
