Rear Drive Shaft/Pinion issues-see attached pics
A little background:
2012 Rubicon 2-DR
OME HD springs/shocks (Front and Rear). I netted about 3" of lift overall, also using TF 1" spacers in front to level bumper and winch sag.
JKS Track bars front and rear w/ JKS adjustable rear sway bar links (stocks relocated to front)
315/75-16 Duratracs on 16x8.5 wheels w/ 4.5 B/S
I've included some shots of my rear D/S and pinion angles:





First pic is rear DS at TC, second is rear DS at pinion
Next is rear DS angle (about 15-16*) and then rear pinion angle (about 8-9*, iphone angle finder, LOL!)
Last is front DS at TC...(ouch!)
So I have about a 7-8 degree difference. Will adjustable rear UCA's be enough to correct the rear drive line angle and the rear TC output shaft angle?
Also, I'm sitting at about 2-3* on the front axle C's, and she's a little darty but not too bad, I'm more concerned about the front DS angle at the TC
Any opinions or comments would be helpful, thanks!

With stick shafts why should the angle be ?
Stock shouldn't be angles parallel like an aftermarket shaft correct? Also, on the c 2-3. I believe there is a better way to see castor bc that area to what I learned recently is not "machined" and can cause off numbers. I also did it at the c but I was told otherwise recently. Mate someone will chime in. :-)

Like Wayalife said you are going to need aftermarket driveshafts. Im not sure if you have adjustable CAs. If you dont you will need at least adjustable lower CAs for the front and adjustable upper CAs for the rear.
