yes, i have tried the "loosen the bolts and drive around" trick and
it helped to a degree, but not completely. That technique may be
suitable for certain instances of alignment and not others, who knows?
Go Westy still flogs their laser tool too, so does that mean...... ?
you fill in the blanks

I have to make clear that I have been dicking around with front diff
and prop shaft out, so the front diff angle may not be the same as
what it was with prop shaft in. . That being said, I do think that
shimming the diff front mount will be my next thing... (no wait, will
check lateral alignment first).

Theoretically, both flange angles should be the same, and that is
what I will be attempting to do. Will report back.

back when Warren was alive, he was puzzling over how to find a sweet
spot for his p-shaft to eliminate the vibes. He called Go Westy,
thinking
that since they seemed to produce such expensive gems of the Syncro
iteration, that they would likely have a method for perfecting this.

They did/do: loosen the frame-to-differential bolts, drive around for
a few
days and maybe 30-50 miles, or until the vibration is gone, tighten
those
bolts and voila!

Warren did it and said it worked. I have no experience with it. What you
say seems to be true, that the transaxle should be very close to 4
degrees
down. The differential will "adjust" itself given this opportunity.
My only
puzzlement about this method is that it has no possible way to adjust
up/
down as that requires spacers, usually at the front (van front) of
the diff.
mount points to point it more up or down.

I do know that the prop shaft I have only needs the transaxle to be
pointed
down "between .8" to 1.2" for it to be vibration-free, which mine is.
Even
after just finishing putting a Subaru 3.0 in the van, with a "high-
mount"
installation, which provides about 2+" more ground clearance, so the
tranny is pointing down more than stock.
