Something inside the rear wheel hub I can’t find the name for online.

I have a weird ring with bend inwards teeth on it inside my wheel. as seen in the pictures it can move freely but can’t be removed. what is this cause I think the bearing go below it. This is from a wheel that when I opened it it had only two bearing balls in it that’s all I took out of it

It looks like a bearing cage, as in this image, but without the bearings

The hub needs to be thoroughly cleaned and all of the old bearings and / or fragments and cage removed first. Just popping a new set of caged bearings in will most likely result in the old fragments damaging the new bearings. And the other bearing surfaces (cup and cone) need to be checked to make sure they are fit for further service.

That would be what I would do, but it would be good to find out where the balls went to, and how they came to disappear. Could you take a photo more depth of field, so that more of the cup is in focus? You need a proper cleanup of that cup and see what else may be wrong.
will do that ones I’m home

That looks like a freewheel, so will need to be removed before a new bearing cage can be installed. Alternatively you can fit loose balls which IMO is better because the load is shared across more bearings.

All this is probably academic however as if the original balls have broken up enough to hide in the nooks and crannies inside the hub then the bearing race is certainly fubar'd and you will need a new hub/wheel.

You need to get that freewheel off and give the hub a good clean and proper inspection to establish its condition.

Any suggestions on how to clean it easy should I just wd40 with a toothbrush or?
 
I'd get the thick off with paper kitchen roll then the rest with liquid in a dish and with a brush. Something like gunk or paraffin or white spirit. WD40 would do as if I remember correctly it's mainly white spirit anyway. Use clean liquid as a final wash, then dry off. Bearings hate dirt.

Pull out the bearing cage (that claw/octopus type thing). It will bend pretty easily and fit out through the freewheel. You can then clean with rag, wd40, toothbrush or whatever.

But like I said, you need to get the freewheel taken off to really inspect the bearing condition. If it is really bad you might be able to see with the freewheel in place once the gunk has been cleaned away.

WD40 is not mainly white spirit, it will leave a sticky mess when it dries. There are so many magical and mythical properties attributed to the stuff as a lubricant or penetrating fluid it's hard to believe. I remember using it in the early '80s for helping to keep the moisture out of my distributor and and plug leads on a Mini, it was good at that and stopping squeaky hinges on a garden gate and not much else.

So many delicate objects requiring lubrication have been ruined by dust sticking to the sticky gunge left by WD40 and movement then impeded. If you want a penetrating fluid, use Plus Gas. If you want to clean the gunk from your bearings use paraffin or petrol.
