My car has gotten to the point where it drifts quite a bit on the freeway, especially if I am hit by a crosswind. I am assuming I should replace my tie rods (all of them) since they are likely 100k+ in age at least. On the parts site I noticed that there are "tie rod ends" and "tie rod assemblies" with a significant difference in cost. Which one should I buy? On diesel giant's pictorial I saw he used the entire new tie rod... all three for my car would be $180. I'll be having the dealer replace them because I don't want to work on steering components.

Any tips or advice on this potential project? I am getting sick of my car wandering all over the freeway, its getting hard to keep it in a straight line!
