Rear pinion angle

So my rear drive shaft binds at full droop, and since I'm going to SOA the jeep in the near near future, I need some input. NOT going to run a transfer case drop because of my skidplate.

Right now I have 3" lift springs, and the shaft binded at ride height, so I built some 5.5" shackles, and now it only binds about 2" from full droop. from ride height I get about 6" of droop. So, if I run like an 8* shim, would that correct my driveshaft enough? Also, whats the bad about having a high pinion angle? I know its bad for a CV shaft, but I never heard anything about a u-joint.

Add a SYE and CV shaft and tilt the pinion up as that requires. Re-weld the perches, don't do shims. Do a proper suspension lift as the tires need and loose the long shackles. Do the job right and it will last and not give problems.

Not to hijack this thread, but I am replacing my tranny and t-case with an automatic and Atlas. Have removed the perches on my 8.8 and plan on pointing the diff directly at the t-case to line things up, then dropping the angle by 2-3 degrees. I have TW CV shafts and believe this should do the trick. Any thoughts on this process?

When I did the 8.8 I ended up with the pinion too high and don't want to go through this again. Thanks.

my shackles aren't that long? As far as the CV goes, soon as I blow out this axle I was planning on going SOA. And I really don't see any justification in getting a new rear shaft and having to lengthen it in 2 months anyways.. I have plenty of time to tinker with the jeep and not so much money

Also, these shackles are 1.5"x1/2" tubing backed against 1/4 plate.
