how do you think they did it before computerized alingment machines?

Thats how they did it. Thats how many autoxer's do it. its very easy and anybody who has worked on cars at all could do it VERY accuratly.

But as he stated, he has some adjustable stuffs, in which case it would probably be good to take it to a shop.

Personaly, I thought it was funny every time someone came in who knew about cars to get an alignment when they could do it themselves.

The very best was when the sales man would sell them a 4 wheel align, when there was a solid rear axle, hahaha.

Anybody who takes there car to Tire kingdom is only going to get the toe in set. 90% of the poeople that work at TK dotn know how to do anything else but the toe.

But yeah, if both measurements on either side of the tire are exactly the same it will be VERY accurate.

i guess I am assuming that most people can use a tape measure...
