in the one section of dodgeram.org, there is a tech who gives different specs for aligning the track then what the shop might use. he says that if the caster isnt the same and with a certain spec (3-4 degrees) that it will pull and drive oddly, even the tech sets it to spec. mine does the same thing, im getting ready to paint the frame and axles blue metallic, so im going to have to redo the alignment and ill try those specs.
