Yea I'd like to see pics too.... that is, if you haven't already taken care of the issue.

To my knowledge, the rod ends on the stock Cherokee steering linkage (aka: track bar & drag link) are not replaceable, well, that is to say only ONE end of each is replaceable, the other side is built into the bar, and cannot be rebuilt.
Upgrades to this include the stock ZJ (Grand Cherokee) set up, but the only thing you gain there is larger bars and rod ends, the issue still remains of there being fixed rod ends on both the tie rod and the drag link.

Pics of your set up and maybe even some good measurements (threads per inch, bar diameter, etc...) would help a lot.
