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.

I would put it on another alignment rack. If it was 1* the 1 would have been in a big red number. They would have or should have told you that would not be wise. I too am not trying to be rude as I am just a dumb hick from the sticks with a 3rd grade education but I know how caster works from a steering stand point as I used to race bikes and caster works pretty much like rake.

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.

I contacted 4wheel parts and was told the printer would be fixed and I could have a printout on Thursday.

I just hope someone that wants to learn about how to properly set caster and pinion angles doesn't read this thread for their own safety

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.
