I met with one of the local drive line specialists today and his comment was simple, kick up the pinion angle as much as possible to get the drive shaft close to level. With the 5 bar link rear axle, this should be fairly easy.
I listened for an hour and saw every type of yoke available. He did point out that I had the long, not short, yoke at the diff (2" +/- difference), which would add length to the drive shaft if I wanted to build a new drive shaft. I also have the smaller u-joints at the trans. Yokes are designed for different angles, the more angle, the bigger they are. The trans yoke is the smallest angle, probably why it is binding.

However, if I was to use a bigger joint with more angle to eliminate the bind, he said it would vibrate like crazy.

Bottom line-the shaft needs to be close to level. Since the trans has no adjustment, it must come out of the pinion. We shall see tonight.
