Well I made the 600+ mile trip with no issues. I am going to pull the drive line some time this week and see if the new yolk has any wear, regardless, I still think the tranny is coming out so I can replace the tail shaft bushing. I'm still not sure what to do about the out of phase drive line yet. Everyone says to line it up, but if GM had a reason for doing this, will I be causing another problem?? I'm surprised a lot of you guys on here aren't looking under your Birds to see if the drive lines are in or out of phase?? It sure would be nice to see how many are out of phase. Should we start a poll?? This information could sure help out a lot of people.
