I just changed ours out this weekend. Like Rubicon, I found the Trail Air Equa Flex bushing on the left side was almost all dust. Just caught it before it started eating into the equalizer. Ours has less miles on it than Rubicon so the quicker you can do anything to your susspension the better of you will be.
Incidentley, I also repack the wheel bearings. Found one of the seals (LF) had started leaking grease onto the magnet. I did replace the seals with an oil bath seal Napa # 22558 if it helps anyone. This is the second seal that started leaking with less than 10K on the trailer. The first got replaced prior to us going to Nashville. I do not use the EZ Lube feature so it wasnt from blowing them out while greasing.
