as far as i know and can see the dodge axles dont have an adjustment or can be adjusted for camber by means of a cam. the alignment would have to disassmble pretty much the whole front axle, press out the upper ball joint and either machine the hole or install a smaller ball joint for means of the eccentric to be installed. if that is the case what did they charge you for all this?
as far as the alingment, the wider tires magnifies/amplifies(the correct word doesnt come to mind)and slop you have in your frontend and also any ruts that are worn into the road by heavy traffic, also like another gentlemen said all road have some sort of crown. i know mine i got nuts on at the alignment shop(the truck wouldnt fit on the rack with the big tires)with my stock tires. the tech just stood there and watched in amazement at how much i play with it till i got it perfect. 0.01 degrees thrust, 0.02 degrees for toe, and 0.05 for caster.
