I've heard bad ones that whirring would be a perfect description of the noise they made, no grind or rumble, just a smooth whir that got louder and louder over coming days, bearing change fixed it. Thinking they can make several sounds there on back or front. Whir means you got some time to fix it, grind or rumble, fix it now or walking in a short time. The grinding means bearing is eating itself.
You jack up vehicle by SUSPENSION not frame, jacked up by frame the suspension is overextended and CVs are not supposed to be cycled under those conditions, the angle will be one not normally seen in use and it SHOULD click if any wear there on an older car. Means nothing if it does, mine all do it. You should never motor car like that under power, can tear up axles.
