I'm going to align a customer's 56 GMC 1/2 ton. It has the original straight axle, an aftermarket steering gear and P/S. Currently the caster is 1.5* positive and the vehicle wanders pretty severely. I'm thinking of wedging that up to about 4.5* positive. Any thoughts?
I believe you are on the right track goldenrog.
with the caster set correctly, a car will wonder towards the ditch on a ball road, so what do you do to the caster to make the car go straight on a ball road? set this way it would wonder left on a flat road.
