3/4 ton axles for my 1/2 ton...maintenance suggestions?

[86 Silver]

Just bought new (to me) 3/4 ton axles for my 1/2 ton...going from 3.42 to 4.10 gears. Any suggestions on what I should do to service them pre-transplant? I don't want, nor do I have the budget to, completely rebuild them. But I also want to do what I can to make sure they're going to be fine.

Obviously I will open differentials and change out fluid.

I think I should redo wheel bearings while I'm at it.

I'll go through brakes (new rotors and resurface drums, new pads).

New locking hubs most likely.
