In many aftermarket shocks, the "tie bar" or "bar pin" can be slid in and out of the bushing with a little grease. As I recall, the bar pins on my originals were bonded to the bushing, and a real bear to remove. I believe my Bilsteins were the same way when I converted them from my TJ to my JKUR. Stand ready for a struggle, and possibly having to come up with new bushings as well. Be careful not to damage the shock bodies.
