Another 2 piece driveshaft angle question

[SCOTI]

While the Spicer info is correct, if you ask anyone w/knowledge on the subject, as soon as the rear-end is higher than the other driveline parts the numbers yield different results.

The best results I got w/my dually was aiming the rear pinion toward the carrier bearing while not keeping it straight.

Totally agree. 2 piece shafts are a little different than 1 piece shafts too. I think mine right now is around 5 degrees down on the tailshaft, 2 degrees down on the drive shaft, and the rear end points up around 5 degrees. It works, but I want to make it a little better. I read a ton of articles when I was setting it and probably confused myself more, but what I took from it was try to have similar angles on u joints and and have the trans and diff point opposite directions at similar angles (trans is pointing down as it points toward rear end and rear end is point up toward trans)
