So my car is making this droneing -grinding noise from the rear,started to click a little on take off which leads me to believe its a cv . But from what I’ve read,it could be the wheel bearing. I’ve read the cvs don’t make the grinding noise.When I looked I can see this grease-lube on the inside of my wheel even seeping from lug nuts.
I’ll pull the wheel and check it out but what do y’all gurus think? Attached Image

Clicking is usually a CV going bad.

Would be unusual for CV to get weeping out at the lug nuts. CV’s fling grease radially. Feel inside the trailing arm bore. If no grease is in there there it is likely a wheel bearing which will have a drone kind of noise.

Did you repack the wheel bearings? Too much lube in wheel bearing will weep like what I see on your wheel.

If you have both a click on take off and a drone at speed you may have multiple problems.

Another way to diagnose wheel bearing is whether the noise changes as you corner (1/4 G or less) which changes the wheel bearing load. Loading the bearing will usually make the drone louder but I’ve seen exceptions to that.
