Thanks for the info^^^When I worked on a front end alignment rack, many moons ago. The wheels were raised and scribed. Then lowered back down. Next we measured with a alignment bar, and adjusted accordingly!!!!!!!!! This is the way that both Hunter and Weaver alignment Reps, taught us to do it! That was applicable to both solid axle and IFS. Most of the pick up trucks back then were solid axle, with leaf springs. Caster was adjusted with tapered shims under the springs. The cars were IFS. The IFS, was shimmed on the upper A-frame, for both caster and camber.
Voices in my head :rofl:,where did you learn this insane method from?google alignment strings and read up on that proven method. the alignment strings gives you real measurements you can work with and adjust toe. plus the suspension is loaded giving the correct on road geometry so you can take accurate measurements.
