Left Rear wheel bearing grinding noise. Pulled axle, it looks fine as does the bearing. Pulled bearing and Toner Ring Assembly. Is this supposed to be 3 pieces? Retaining ring, spacer, toner ring (splined rubber sleeve). Seems like that loose-fitting spacer could be the noise culprit, except kinda hard to believe it would give a growling noise. Or is it supposed to be attached to the toner ring?
