A good possibility exists of toe in being incorrect as 2 of your symptoms are indicators. The outside cupping as well as the wandering. Light front loading on the XC chassis can also cause the wandering. Have you had a 4 corner weigh done by a reputable outfit? FCOC members (a chapter of FMCA)normally have that available at their rallies with good information available as to what problems incorrect weights can cause. Tire pressures need to be correct and can only be ascertained by knowing the weight being carried by the tires or axle.
