Aligned twice in the past year, but the tie rod ends are now going out? The dealer didn't notice or recommend replacement in either alignment? I'd take a close look at everything else up front before spending more on a third alignment or even replacing the tie rods. There might be something else wrong, like LCA bushings, a ball joint, etc. Are there any other symptoms: tire wear, handling, difficulty returning to center?

If there is nothing else wrong with the front end, and it's currently in-spec, and you can accurately measure the existing tie-rod ends center to center, and then accurately install the new rods with the same length, there's a reasonable chance it'll be close enough. If the old rods were worn enough to clunk, there's no guarantee you're starting from a good spec.

Regardless, even at 4k miles per year, rapid uneven wear may cost you more in replacement tires, not to mention possible problems with handling.

I'd at least have the alignment checked after the repair.
