You did say 1.5 ton, and I said 2 ton.
I know there are differences in the two, was not aware of width differences but it's not surprising.
Who else can measure some AD 1.5 and 2 ton axles?
Measuring technique is also important. It ia a good idea to clamp or have someone hold a straight edge on the wheel mounting surface (wheels removed) while you do the same on the other side and pull a tape measure parallel to the ground between the two. Also measure in front and behind so you can average and remove toe-in from the equation.
