The old Ford Twin-I beam suspension was notorious for wearing the outer edge of the front tires into a saw-tooth pattern. I would do 5,000 mile rotations then at about 25,000 miles have the tires remounted and balanced turning the inside of the tire to the outside. It worked out well for me for many years. I just put new tires on my 88 E-150 and if I have the van long enough will do the same thing. I just make sure when buying tires that could be mounted either way on the rim.
I believe only toe in and toe out was adjustable and anything else required cold bending the I-Beams. Not many people were able to do it properly, it was expensive, and like playing Russian Roulette with 4 bullets in the gun. They have since improved the front ends on the trucks and vans.
