Could be, when you set it on the ground, with the tires on, the stagger causes just enough bind, to make it hard to rotate, may need just a half turn one way or the other, on the ladder, or one or the other of the rear radius rods, if you can get a little pressure, one way or the other, sideways on the torque tube, you can tell which way it needs to be adjusted, to re-center and allow for the stagger. Bob!
