Many times, the symptoms you describe can be caused by the right (passenger side) inner driver or the driver's side inner driver bushing.

Try getting it balanced by a Hunter first though as the passenger side inner driver in about $250 from Eeuro. I won't even get into the driver's side inner driver bushing - do a search on that one.

If being caused by the passenger inner driver, what happens is that some grooving occurs in the cup that the tripod bearing floats in. The vibration you feel on acceleration is caused by the bearing moving in and out of the grooving. It is mostly felt during acceleration because of the additional stress that acceleration puts on the parts (and the grooving occurs on the portion that presses against the bearing on acceleration.

My local indy thinks it may be a problem with the hardening of the original castings as he has never seen the problem recur in cars where he's replaced the inner driver.

You should be able to tell before replacing just by taking the half-shaft off and feeling in the cup. If there's grooving, you'll feel it.

Balancing is not for the life of the tire. No tire wears so evenly that you only need to balance it once - it's something that should be done periodically. Additionally, the Hunter machine (and others like it) account for rotational balance as well as side-to-side balancing. Not checking for the side to side balance will allow the tire/wheel to wobble at some resonant frequency/rotational speed so it can make a difference - especially on a car like the Saab that uses such a long inner driver shaft only supported by a carrier bearing near the end.
