Jerry:
I tried the only big truck shop in town a couple of weeks ago. They said they knew how to bend the axle, but their alignment testing equipment was physically to large to fit my small truck.
I have a set of Snap-On magnetic caster/camber gauges that attach to the hub, and all you have to do to read caster is turn the wheel in and out 20 degrees each way and read the gauge. Camber reads directly, as long as the vehicle is on a level floor. Any alignment man who understands basic geometry should be able to get an accurate reading, while they're set up to do the bending. Want me to send them to you as a loaner?
