After paying a half-witted tire shop for a $hitty alignment when I got new Michelin LTX's mounted 2 months ago, it started pulling to the left slightly after about 2 weeks. I decided to perform my own toe alignment.
Procedure;
1) Put van on flat surface and open driver window
2) Set up dry line on driver side. Square up dry line to rear wheel measuring from front and rear rim edge of rear tire. NOT tire. This is going to take some finesse, precision and accuracy so take your time and get this perfect. This establishes your line to square the front wheel to.
3) Now square up front wheel to dry line(the opposite of what you did in the rear). Adjust position of wheel using steering wheel (engine not running). Now the driver side should be perfectly square against dry line.
4) At this point you want everything as a fixed point on the drivers side. Don't touch anything and move to passenger side. Set up second dry line there and perform the same procedure starting at rear wheel. Once you're done there you're ready to see how far off your toe is.
5) Move to front passenger wheel and pull a tape on front and rear of rim edge. The dimensional difference between those two measurements is your toe. Perform your adjustment if necessary and go back and measure those two points again.
Tire shop alignments suck. Once I figure out how to post photos here I'll put up a couple.
