I know that it sounds crazy, but I changed universals in my toyota, and I thought that i marked everything pretty good( one piece shaft). When I put it back I got it off a couple splines and it made a terrible vibration, moved it back and everything was fine.

 

I did a 580 mile turn this weekend crusie even and steady @ 55,60,65,70,75,80,85 welll thats all i will admit too. Still no vibration.
