Persistant vibes..

I wasn't feeling very good today, so I took off of work. But since I can't stand myself if I don't get anything done for the day, I went ahead and drove up to Houston drivetrain service and had them check out my problem. turned out the place that made my drive shaft did not do a very good job balancing... I had these guys do it and at the same time converted it's over to large u-joints. Night and day difference, though I think I have the slip yoke one tooth out of phase. I'll pull the shaft back out this weekend and shift the yolk one tooth over but it looks like that's all it was, poorly balanced drive shaft. I didn't even think of it, because I ordered it from a professional shop.
