I used a track bar kit that I found somewhere on the net but have never seen referenced here. Linstead Alignment in SD makes and sells them, they have a wbsite but the last time I tried to go there, it did not work. Their toll free is 800 432-0017. The kit replaces the weak parts of the ball end with a machined steel cup, threaded sleave and threaded cap that can be adjusted for pre-load and to accomodate wear if needed. It works in a similar way to the Lukes link but I think it is stronger and cleaner. They charge $62, less if you buy more. It requires some welding but it is simple stuff. I've put in a couple of them and they seem to working well.
