I had a problem with my car beginning to vibrate at about 65-70 mph and
progressively getting worse as speed was increased. I tried everything
except the driveshaft, including Panasports...still vibrated. Then I
sent my driveshaft to Ft. Wayne Brake a Clutch in Ft. Wayne, IN and they
sent back my driveshaft painted and balanced with a repaired yoke. I
didn't even suspect I had a yoke problem.
That was the culprit, so I now travel at insane speeds with no vibration
at all.
Oh, BTW I have no idea the which way around my driveshaft was originally
connected to the front and rear flanges, so I would surmise a properly
balanced driveshaft makes the relationship somewhat unimportant, except
that according to the Haynes Manual, "the forked yokes on both shafts
will have their axes parallel to each other". Whatever the hell that
means.

Perhaps someone who has experienced the symptoms of an unbalanced prop
shaft can make a comment on whether that results in the kind of behavior
you are experiencing. I know that the shaft is supposed to be marked
and go back the way it was installed at the factory. I know the issue
has been discussed in the past - I just don't know what the car feels
like if you don't put the shaft back correctly.
