High Speed Vibration from the driveshaft??
At speeds at or past 100mph there's a hum or whine from either the tranny or the driveshaft. Is this normal just cuz these cars aren't high speed cars or do I have a problem coming up?

O.o Holy hell, I haven't gotten my car up past 80 yet... But it sounds like it may be normal... I don't know how fast the FB's are designed for...

I have been to 110/115 and never had a whine. If that helps any.

I've been to 110 with no problem. Could be a U-joint problem. Or, slim chance, low fluid.
