I'm trying my best not to take these comments as rude. But I'm an educated person quite capable of reading the word caster and reading the numbers in the columns. So unless there machine is off, it's 1*. When I got in the jeep I had white knuckles expecting to be scared by the choice I made. I was obviously very pleased it still drove well. If I noticed anything it's that the steering wheel is a bit lighter at parking lot speeds but that's it.

Not questioning your ability to read but do you understand how caster affects your steering, stability, wheel self-centering, etc? The reason you have so many people reacting this way is that the numbers you are telling us are completely contradictory to everything that is known about how to properly align a JK. That's all. We are trying to help you avoid a potentially very scary driving situation.

Like I already posted. I have taken the jeep up to 75mph with absolutely no difference in stability prior to alignment. I really don't know what else to say at this point.

We usually run with negative caster. In fact, we build reverse caster corrected housings. That way we can have pinion at 4* and caster at -4*. We find it provides a much more spirited driving experience.

Who's front shaft are you running??? I had same problem awhile back. Chased everything in that front end, parts, alignments... Had local shop spin balance front shaft still vibrated, sent it back to the well known mfr. and they tested it and sent it back and it still vibrated.... Someone reputable told me to dump my well known after market front shaft and put a Coast shaft in.... Problem solved. Won't run anything but a coast shaft from now on.
