You can replace the bushings in the tie rod ends without replacing the whole tie rod.

I had mine replaced because they were worn out and the car couldn't be aligned.

They were fairly cheap - less than $100.

Worn out tie rod ends will make a big difference in the quality of the ride. If they're worn out, you may experience a sloppiness in the steering wheel, and / or you may experience a tire wobble, very similar to a tire that is out of balance, except that the tire will wobble from side-to-side instead of up and down.
