So, here is an example of the target vehicle for this whole exercise.
This is a Ford E350 Class C sitting on a parking lot at a casino in Laughlin, NV. The question is, does this vehicle have a caster of +5.0 or over? The only inconvenience to the owner was to crank the steering wheel full right and allow me to take 4 pictures.
The left hand wheel camber measured about NEGATIVE 1.1 Degrees
The left hand wheel was cranked about 27 Degrees to the Right.
The right hand wheel camber measured about POSITIVE 2.6 Degrees
The right hand wheel was cranked about 32 Degrees to the Right.
The Estimated Caster K"
K = (180/3.14) X (2.6 - (-1.1)) / (32 - (-27))
K = +3.6 Degrees
In my opinion this vehicle caster could be set better FOR HIGHWAY DRIVING.
Just to confirm, it appears the shims are fixed shims probably installed on the production line.
