If it’s a cup and cone hub you can get a whole axle assembly with new cones and spacers. There’s essentially a Chinese standard cone and a Taiwan and it’s likely one or the other.
If it’s a cartridge bearing you just whack it out and whack a new one in (I’m simplifying here)
Don’t discount it might be something stupid. I learned about the cones chasing a noise on my MTB. The new cone didn’t fix it because it turned out to be the wheel reflector
