Right Rear Ball Bearing cracked?

when I’m driving I can hear this bad grinding sound at my right rear tire. my camber back there is TERRIBLE, not sure what the hell happened to it. I think the ball bearing is busted up.

anybody know how to diagnose the problem to make sure that’s what it is, and if it is, what do I need to replace / fix + tools?

thanks!

EDITUPDATE* sounds like a gun shooting now when I turn a hard left, huge cracking noise whenever I make a left turn. not just one crack, but like mutiple cracking until i straighten out… when i’m rolling i hear a grinding noise. please help! i think also my wheel wobbles back and forth a bit (my friend told me)

is it the ball bearing in the rear wheel? if so how do I replace / repair? Please help!? thanks!

please help!? anybody?

Jack up the suspected wheel and wiggle it. If theres play in it then its probably your bearing.
