Cricket,
What I did was make with white-out a line on the
axle tube in line with the movable part of axle, In full down position and when loaded. Since these axles dont move much it was hard to tell even if my axle was working (with tire flex and all that) gave me reference points to confirm that my axle was indeed working. or in your case is one side of the axle actually lower, or is it tire inflation difference?, illusion with one side of body being lower?. Think with the smaller
tires it just compounded the illusion that one side is lower than the other. And yes bend in middle of torsion axle is normal
