Good sleuthing Vaughn! I would never have thought that information was even available anymore.
One question. Are you SURE the springs are referred to as "underslung"? My springs all mount to the "top" side of the axle housings...
As far as heat treatment, The majority of the cylindrical parts we produce here for the big AG and construction equipment manufactures get heat treated. Some of them come back to us again for further machining after they are hardened.
It is not unusual for us to drill four or five holes through the length of the cylindrical parts (about 12-inches in overall depth, and approximately 5/8-inches in diameter). Then send the parts out to be heat treated. They then come back and our check pins used to assure straightness and alignment of the holes will no longer pass completely through the holes, even though they did before the heat treatment process.
This of course means the parts now fail inspection. Nine times out of ten, it is not the fault of the heat treatment process, of the business that is providing the process, it is because of the really crappy steel coming out of Communist Red China.
I would not want to be in the business of heat treating parts to harden them. One never knows how the bad material produced today is going to react, or what shape of a pretzel it is going to turn into.
The U-bolts that I had bent for me, and that I personally stood there and watched the process, were obviously very soft steel.
