1. An axle condition evaluation system, comprising:

  • a first sensor unit disposed on a first associated lateral side of a vehicle inspection lane;

    a second sensor unit disposed on a second associated lateral side of said vehicle inspection lane, said second lateral side opposite said first associated lateral side;

    wherein said first sensor unit is configured to acquire a first plurality of distance measurements along more than two measurement axes in a first set of measurement axes to a surface of a first rolling wheel assembly on an end of an axle adjacent to a first associated lateral side of a moving vehicle passing through said inspection lane in a generally straight line, but neither along nor parallel to, a longitudinal midline of the inspection lane;

    wherein said second sensor unit is configured to acquire a second plurality of distance measurements along more than two measurement axes in a second set of measurement axes to a surface of a second rolling wheel assembly on an end of said axle adjacent to a second associated lateral side of said moving vehicle;

    wherein each of said first and second sensor units is operatively coupled to convey said first and second pluralities of distance measurements to a processing system configured with software instructions to determine, from said acquired distance measurements, a total toe of said axle without determining representations of individual toe for said first and second rolling wheel assemblies.
