911! Hub fell off and need help!

[Truck Guy99]

I'm bringing home a homemade trailer that I believe has 3/4 ton axles from a square body chevy. The hub completely fell off taking the wheel and tire with it. I have a spare axle for it that I can take the hub off of but can someone give me a list of tools or maybe a step by step? Oh, and is there anything special I need to replace it? I'll be on the side off the road to do this job because it was dark and I had to leave it so I can't afford to miss anything

3/4 ton rear ends have full floating rear axles. the axle has nothing to do with holding the hub to the rear end. the bearings & races hold the hub to the spindle. you can pack the rear bearings with grease just like you do the front ones. You have apparently ground off the bottom portion of the backing plate from dragging it. I would just remove it. so you will need the inner & outer bearings races and seal. be sure to properly adjust the bearings and lock the retainer securely between the two axle nuts.
