I've gotten my 2012 JKU pretty well dialed in. After installing front and rear adjustable track bars, control arm correction brackets, new shocks and tires, fresh swaybar end links, and a beefier swaybar, she's riding pretty nicely.

There's still a drift/pull to the right with hands loose or off the wheel. I checked the thrust angle on the axles and they're only 0.05° off, about 1/16", so I'm not sure how much that's contributing. Nothing on the alignment sheet really screams at me, so I'd love to get some input from you alignment whisperers out there!

Bonus question: I'm getting an occasional single popping sound (not terribly loud, but noticeable) from the rear of the Jeep when making more extreme turning maneuvers, like U turns, roundabouts, etc. It doesn't happen all the time, so it's difficult to figure out what conditions create it. I went back and made sure all of the rear components were secured. The lower passenger shock bolt and rear swaybar link both need a little snugging, but everything else seemed pretty tight. My theory right now is, if it's not a sway bar link, it might be the swaybar to frame bushings might need a little grease.

 

Drifting to the right is normal, manufactory set it up this way. My guess is if you fall asleep you will drift off the road rather than into oncoming traffic.

 

To pinpoint sounds in the rear, you can often replicate the sound by getting on one side of the jeep, put both hands on it, and push to the other side getting it rocking in motion real good. This will get your suspension in motion and often highlights the sound. That sounded like a sway bar link to me....which if undertorqued would make a pop as the body rolls (in a turn) or gets off camber.
