Ryan:
My 129's biggest front end load is the QA-42, and we don't have a particularly dusty/sandy environment, but in the 21 years that I've had it, I've probably replaced at least six or eight of the stock tie rod ends. Quiet honestly, I think they may be the only under engineered component on a Cub..... With the steering box tune-up that I'm planning, I'm going to convert to heim based tie rod ends also. Thanks to Terry for the research.
