Airbur, I know the WH tech piece mentions that the radius arm caps are likely torqued in an unbalanced fashion and when the axle is removed and the radius arms are laid flat on the ground, one is usually higher than the other. Have you considered intentionally imbalancing the torque to reverse the effects of the lean? Basic idea being, if the PS radius sits off the ground while the DS sits flat, or the both sit flat, adjusting the torque so the DS sits higher.
