Expert Reply:
3500 lb axles have the most common and most consistent spindle sizes. They are typically 1.73 inches at the seal, 1.38 inches at the inner bearing and 1.06 inches at the outer bearing like # TRU24FR. I've attached a video to assist.
I've linked the page to all of the options for hubs or hub/drum assemblies for this size spindle. There are 4 different sizes for 5 bolt assemblies and I've attached an article to assist.

Wondering if anyone still uses 1.5" x 1.375" spindles? I'm looking for bearing/hub assembly for an axle I currently have but seems like these dimensions are no longer used? Would you have any leads on where one could find some (perhaps old) stock in these dimensions?
