My original SPC UCAs with sleeved poly bushings on the left; new UCAs with the X-Axis joint on the right.
TL;DR - the last time I got an alignment, the tech mentioned that the rear passenger side bushing on the upper control arm (UCA) was starting to get a bit loose. After some consideration, I decided to install completely new UCAs, with lifetime joints so I never have to worry about those bushings again.
