Planning on installing my Currie adj UCA's out back and dialing in my pinion angle. Was browsing 4x4wire.com for more information, and that site said "The pinion should be 2 degrees below being pointed straight into the drive shaft"
that sound about right? I checked my paperwork that shipped with my SYE and that doesn't give any details, just says "the rear differential should be pointed at the transfer case output yoke under normal driving load"
Also plan on picking up one of the magnetic protractors from HD, to get an accurate measurement

1) Apply PB thru the frame onto the nuts for the frame ends of the UCA and at the axle ends.
If you bust any they run about $12 for a nut and bolt. (Just bought some from Jeep last week )
2) Remember that when both UCA's are disconnected the axle can/will want to violently rotate forward or backwards.
I used a pair of hydraulic jacks under the differential to prevent this from happening. One under the yoke and one under a lip on my Rockcrusher diff cover. Once the stock UCA's are out you can raise/lower the two jacks to set the pinion angle. Once set you can adjust and install the ends of the UCA's.
3) You need to set the pinion angle with the full normal load on the rear springs/axle. (Not drooping)
Apply antiseize to all of the bolts, bushings and UCA adjuster threads
Also, a pair of good ratchet straps will help pull the pinion down (aka rotates the upper control arm mounts forward). The jack is used to rotate the brackets toasted the rear.

Mmmm - Toasted Rear. Yummy
Pacifism is a shifty doctrine under which a man accepts the benefits of the social group without being willing to pay - and claims a halo for his dishonesty.
Picked up a magnetic mount protractor from HD, $8, cheap enough. My Curries come with new HW (with greasable fittings) so that base is covered. Didn't notice before but my UCA's have mounts to hold the rear brake lines in place / out of the way
Any work arounds for this? I was thinking of cutting the brake line mounts off my stock CA's and tacking them onto my Curries, really don't want my brake lines flopping around under there. Is there an option B? My plan was to get this done today but that's not happening
oh yeah, I found out my IPOD can survive being driven over, with big azz Swampah's
My glasses..... not so much
