It's a fight for the best steering you can without causing front driveline vibrations.
Anything over 4.5 degrees will give you nice steering, going to high will cause vibs

I initially had mine set at 6 deg, had some vibes, and now it's back at 5 deg and it feels great. Not flighty feeling in the highway, no driveline vibes.

Project JK has a do-it-yourself front end alignment guide. Everything you need to know should be in there. I printed out a copy that I keep in the garage and also take on the trail with me, just in case. I also printed out the torque specs document on the Project JK website. Great documents. Many thanks to Eddie for putting those together!
as mentioned, there really is no need to pay someone to do what you can do yourself and with ease. this write up should help you out:

Thanks for the tip. Does this recommendation apply to stock shafts or aftermarket double cardoons?
this is for aftermarket shafts. a factory shaft will allow you to get a bit more positive caster but, doing so will cause the cv boot and joint to fail prematurely. more would be better but, about +4° is where you want to be.

Thanks Eddie. I was running around 6.5 with prior 3" lift. Switched to the Evo Bolt-on coilovers and running just over 4" now and noticed a slight pick up in vibes. Had both shafts re-balanced and ujoints serviced and still noticed vibes, so I'm going to try dialing castor to between 4-5.
are you sure the vibes are coming from the drive shaft? the more positive caster you add, the more you should feel vibes. if anything, you will need to go less.

Yes, I agree, that's what I'm going to try. At 6.5 positive castor going to try 4.5 positive caster. My lift added about another 1" or so from 3" to little over 4". Your recommendation was is helpful and timely. I'll let everyone no how it turns out. Thanks:thumb:
