You know what? I questioned this myself with my front axle on my 1940 1/2 ton, because my axle is also bowed towards the front. I placed a straight edge along the centres of the kingpin holes, and measured from the straight edge to the u-bolt holes. Both sides measured up so close to each other that I am only going to assume that this is the way it should be and I am going to work with what I have. I also checked my axle over very closely and I could not find any visible mark or ding where it may have smacked anything.
