You will get the same tire wear on the out side of the front passenger side if in need of a front end allignment. I was told same by an individual that had same wear. He had front end aligned several times with no corrction. That's when he found many places do not know how to do the allignment on a Spartan chassis. He found a place that checked with Spartan, aligned it correctly and problem solved. I had the same tire wear and asked and found someone who knew how to align the Spartan and it drove better and odd tire wear was also gone. The correct procedure has to do with checking ride height before proceeding with anything else but beyond that I am in the dark. It is well worth checking before you pay for new ball joints.
