driveshaft angles with IFS and Dirty dingo
 

I have searched and searched and think I have this all correct now but it just felt wrong making a spacer on the trans mount. setups is the IFS xmember 6.0/4l80. the xmember would not fit turned 180 so I had to do it this way. The spacer was needed because I am measuring up 5-6 deg on the axle. with the 2 piece shaft. I understand it as I had to have the 1st shaft on the same angle (5-6 deg). With my dirty dingo mounts it needed a 2" spacer. this made the engine almost the same angle as the 1st shaft. does this seem kosher? (cross posted on FB)

It looks like the axle is 5 degrees pointing up

Most drive trains slope down 3-5 degrees to the rear end.

When you give it gas the rear end will tilt up some

A driveline that is equal and opposite is what you want. Meaning axle pointing up 5 degrees with the other end pointing down 5 degrees. If one shaft is 0 to 0 that works too

"0" degrees of angle on a u-joint is not good... angle is what makes the needles roll in the cup to keep them lubricated. ..
the +5..-5 is ok but most shoot for +3..-3.

so the axle is fixed and not sure I want to get into the shims route. so if its 5 up , i read the first shaft has to match. the others can fall into place wherever. as far as the 0 degree between the first shaft and the trans. why is this bad?

Nice pic.
I'm running a CV joint on my 4x4 and the rear axle is ponted up at the t-case. Do to the lift and doubler it's pointed way up, creating a zero degree angle on the u-joint at the axle.
