I'm going to swap to Titan outer tie rods, with Titan inner tie rods, so I just ordered Hitachi Titan inners/outers. I'm currently running PRG heimed outers and I'm getting a pop just left or right of center when I turn the wheel. I also was getting really bad popping when turning with aired down tires while in Moab. Hopefully, it's just the inners going bad and I caught it before the rack is toast. FYI, I'm just under 59K miles on the truck. I read through several posts on FB talking about how heims can kill the the rack pretty quickly, with people like Bill and Zach attesting to the carnage heims can create, I think it's time to get rid of mine before the rack goes.
