I won't say "It can't be.", but remember It was stated that the hub runs
true. This is not likely with a bend half-shaft or axle.
However, if the wheel is not square to the hub:
((>All I can detect is that the space between the brake drum
>and the outer edge of the inner wheel lacing flange could
>have as much as 1/32 - 1/16" variation from closest to

then the described wobble could occur. Yes, a small angular error at the
hub could, with the 19" diameter wheel, translate to a very significant
run out at the tire.

Sure soiunds like a bent axle to me. It's super-easy to pull the shaft,
put
it on a flat surface, and roll it. Why not give it a try.
