How to properly lube a Coda Expert Sealed Cartridge Bearing (Rear Wheel Hub)?

[lidation]

My bike has a Coda Expert Sealed Cartridge Bearing in the rear wheel hub. How do you lube it? I opened up the rubber seals and I saw those ball bearings were fixed by invidivual cups. I can't seem to be able to get the grease to those balls. What is a proper way of greasing those ball bearings? They seem to be a little dry. See photos attached. Thanks!

Apply some on the head, and shaft, and rub it around. Make sure to get it down the shaft a good bit. Put some more on the other part and maybe a finger in or so. To get it on the balls, put some on your hand and smear it around.

Just pack the grease in. Personally, I would disassemble the hub to get the bearing out and work on it outside of the hub. If you don't, I wouldn't apply any cleaners, just pack the grease and go.

Sealed bearings are not supposed to be lubed up. As you already openned them, just clean them up with a good degreasing product and relube with a good bearing specific grease. It'll reach the balls just rotating them. Beware not to ruin the rubber seals, as they are the protection against sand, mud, water or dust

It depends. Sealed cartridge bearings are usually not meant to be regreased, yet often times what they come with stock is pathetic in terms of grease and if you can regrease them, you should. A grease-gun would help immensely here, as you could put the head in-between the balls and shoot a little grease there. You don't want it so packed in that the balls can't move freely anyways. It's hard to tell if your hub is some kind of cup-n-cone setup or just a cart bearing from the picture, but if you can get as far as you have, you should absolutely grease it.
