The ring Hyflyer is refering to is removed after you get the hub off & the seal & outer brg. You only need to remove it if you want to replace the outer brg.
There might be a thrust washer behind the last spindle nut with a tang on it that fits in the groove. It could be hung up. If not & the shoes are not dragging then the inner bearing must be stuck to the shaft. If thats the case prying it enough to pull the seal out.
