6" lift Drive Shaft Angles

Calling all self proclaimed mechanical engineers. I have a 08 Taco, double cab, long bed, with a 6" lift and two piece drive shaft. To no surprise I have a drive line vibration and I believe it is angle related. In pic. 1. I've started the process to align the first piece of the drive shaft to the same angle as the T-case output shaft. In pic. 2. the first piece is at .03 degrees of the T-case output shaft. You'll then see in pic 3. I'm showing the center support bearing that is from a 2500 HD. I shimmed up the center support bearing temporarily to change the angles. In pic. 4. the second piece that is at 8.5 degrees and the last pic is the rear diff. pinion angle at 2.9 degrees. If I'm correct the working angle is 5.6. My intent is to align the first piece to the T-case then focus the second piece. My thoughts here are to put in a double cardan at the 8.5 area. What I'm asking of Tacoma World are your thoughts and experiences. Of course I will need a reputable shop to help out.

Thanks all

The angle here is the same as the T-case output shaft.



First piece of the two.



2500 HD center support bearing, shimmed to match the T-case output shaft.



Second piece of the two. This is where I would put the double cardan.



Angle at the rear diff.
