Here's a pic of one of the 4 Large TeraFlex Clevite bushings that was just replaced on my JK. I had the 2nd TeraFlex long arm kit ever made for a JK installed back in 2008. This bushing is still in good shape and didn't really need to be changed. R&D wanted to see what kind of condition they were in before I sold my JK off, hence they were replaced.
