Fastrax review and alignment questions for the pros.
You should be measuring "about inline" with the spindle. I simply use a scribe which you can build. Jack up one tire at a time, barely off the ground, under the LCA. "Anchor" your scribe and rotate the tire to provide at least two marks 1/2 turn apart (180*) on each tire. Then tape between, the difference, etc
Because I'm usually working alone, I actually bought a toe gauge, although you can build one. This one turned out to be for large trucks, and I had to saw it down it was too tall
This is the scribe and toe gauge I bought off egag
I scored some beat up Ammco turning plates and caster/ camber gauge here locally
You don't really need this fancy stuff but you DO need an angle gauge to measure camber. Caster is figured mathematically by turning the tires in and out I believe its 22.5 degrees, take the difference in camber readings, and multiply by 1.5 to get caster. Search it you can find destructions on the net
