2017 Nissan Rogue Sport AWD.
Passenger rear wheel begins humming at 5 mph and gets louder the faster you go.
Wheel bearing/hub assembly seemed most likely candidate as tires are almost new and balanced properly.
I replaced it, torqued the axle nut per specifications, but to no avail.
Rotor looks fine so I went ahead and replaced both sets of brakes on back even though I know what grinding brakes sound like.
Given the noise is most definitely on the passenger side only, I think my only other possibilities are the CV axle or the rear differential.
It literally sounds like an electric motor spinning up.
Edit: Forgot to mention… my wife hit a deer and it destroyed the radiator.
We had it towed to mechanic per insurance.
She picked it up and said the noise started immediately… and waited 3 days to tell me.
I wonder if the tow truck driver possibly did… something wrong. I highly doubt the mechanics had anything to do with it given the problem and where the damage was, but what do I know.
Now, of course, they, like I, say, “why did you not come right back? We can’t cover that.”
