I am pretty careful as to the treatment I give it, but was still uncomfortable about the rearward pressure put on the front axle pivot tubes if you ran over something or dropped a front wheel into a hole while carrying a load with it. the best thing I could think of was a wishbone running form the front spindles to a pivot under the torque tube like you see on many of the 50s and 60s wide front, such as the Fords, etc. but that was a little beyond my abilities, so I finally settled for adding a couple of gussets at the point where the vertical tube welds into the horizontal one.
it is not pretty, but should strengthen that weak spot some. I might not worry about that particular spot, but I have seen several spindles that have been broken loose tright there, and welded back, though frequently not properly aligned first. These were not on rigs with loaders, either.
He's go'na write you up!!
