Take a tape measure and measure the distance from one point on the front wheel or axle straight back to a point on the rear axle or tire. Repeat for the opposite side and use the matching locating points. The measurements should be the same or within 3mm.
The truck may be square sitting still, but a bushing or something else may flex when driving causing a tracking problem. A vehicle will pull toward the side with the narrower wheelbase. A tracking problem will cause tires to scuff on the edges as well. A mismatched rim, different in offset or width, will also cause funny handling and pulling.
You can also try driving in the oncoming lane and see if the pull changes direction. If it does, that means your front end follows the curve of the road. This applies if you live somewhere that the roads are curved for water runoff. The quadcab longboxes are really sensitive to the wind and are quite picky on the curved road surfaces.
Dwayne--Good luck with getting your truck fixed. If they can't get it fixed, Dodge will be forced to buy it back. Then the truck will be sold to some unsuspecting person who will continue to experience the troubles. Your truck has to be fixed, otherwise accellerated tire wear and poor handling will be with the truck for the rest of its life. And heaven help you if you ever drive on ice, that truck will want to turn sideways at 25mph as the axles push the truck in two different directions. I have personally seen this in one of my vehicles, and it is scary.
