I just had my 07 JKU aligned after lots of front end work. I installed a Rebel coil over set up and installed new tie rod ends. The first attempt at aligning revealed a worn unit bearing. I had to bring it back from shop and wait for the bearing kit from Teraflex to arrive. I installed the new unit bearing on the Tera 60 and took it back to the shop yesterday. These are the numbers before and after. It runs nice. It "wandered" before, now it is dead straight and rolls easier and a little quieter. The specs are dana 60 high pinion, big brakes, 40" patagonias.
