I replaced the tie rod ends with 555s and new budbuilt tubes and I can't believe the difference it made. I still have to get it aligned, but the difference at all speeds is amazing. The only tricky nut was the pitman arm connection, but a little bit of heat did the trick. I used a $10 pickle fork for the separation work. It now looks shiny and beefy. Going straight on the highway. Priceless.
