Ok. Take 4 jack stands. Set them up in such a way so that they are at each outside corner of each tire, about 6" or so to the outside of the sidewall and a foot or so behind the rear tires and in front of the front tires.
Get some twine and tie a section to each side jack stands so that it is tight enough to not droop any. You will have a right side string and a left.
Now, position each side string so that it divides the rear tires exactly in half horizontally. Then position the string so that it will be equidistant from both the rear half and front half of the rear tires. I usually use 6". This is not critical as long as both sides are the same. you will of course need to re position the jack stands to accomplish this.
Repeat the same for the front, making sure not to disturb the rear. If you do, simply readjust so that the string cuts all four tires in half horizontally.
Once this is done, Center the steering wheel and find a way to lock it in the center. I have a steering wheel holder from when I did alignments.
Now, adjust each side's tie rod sleeve to put the front tires an equidistant amount from the strings both on the front half and rear half of the front tires. Once that is done, adjust so that the front half of each front tire is 1/16" MORE on the front side. This will give you a total toe in of 1/8" which is just right. Lock the tie rod sleeves down. Done.
Of course if you have camber/caster gauges, now is the time to break them out, too.
