Typically your first trip after replacing all your steering components would be to the alignment shop. Being that I had already spent my ramen budget on car parts, I wan't to keen on that idea. Since toe settings are responsible for most accelerated tire wire I found a solution to keep that in check.
Toe Plates. I got the idea from my roomate who was an engineering student and intern for a race team. They use them all the time (a much nice version than what I created for $8 at harbor freight) to set toe during qualifying and such.
The concept is simple, line the plates up parallel to the face of the wheel (I used the bungie cord to keep it snug)
Then measure the distance between the front edges of the plates and the back edges.
If the distance between the front edge(s) is greater than distance between the rears then you have toe out. If the opposite is true you have toe in.
