Bob to me it seems to be a method of preloading the bearings using the shims as adjustments for the bearing clearances ,by doing this when you tighten up the nut on the end of the shafts it locked tight the centre race of the bearings so there couldn't be any movement. I've often wondered over the years with these old trucks that when the bearings were to be adjusted and whoever was doing the job had no shims for adjustment so they just left the spacers out. If you have no shims or spacer and adjusted the bearings the bearings will end up in the same position on the shaft anyway and it's a lot easier to adjust the bearings, just have to make sure the nut n the end of the shaft is well secured.
In the very first front axles that were used the cv joint didn't have a ground shoulder on the inside side and they used a spring and plunger or shimming method on the very inside ends of the axles, the only reason I can think of they would've used this method would have been to push out on the axle to hold the cv joint firm together. Never seen any of these early cv joints down under.
Does this make it any clearer or are you all even more confused? because I can easily get confused myself these days.
