For what it's worth, I got mine when I got the new shocks. My TJ has 204,000 miles on it, so to replace it at the same time seemed like a no brainer. I mean no disrespect to the folks who feel it isn't necessary, but unless the steering stabilizer is flat incapable of wearing out (which is not the case), then why not replace it along with the other components? I think it's like $50. I'd do it. Just my opinion...What do you guys think about the Rancho steering stabilizer?
