Wheel bearings? Noise at low speeds, sharp turns

Trying to diagnose a noise that sounds like wheel bearings, but at 63K it seems a bit unlikely. When turning into a parking space it makes a noise that sounds a bit like rubbing or scraping, don't hear anything going straight or around normal driving corners. Not clicking ot popping like a CV joint. Had the wheels off and rotated the assemblies and heard nothing, felt nothing. The concern is that we have a trip scheduled to DTW and it'll be close to 700 miles round trip at Michigan freeway speeds. At this juncture I'm thinking of taking the big Bronco despite the extra gas it will chug down. It does seem to be coming from the rear more than the front.
Anybody else experience this? Off course this comes up right before the dash to Detroit!

Been doing some research, looks like it might be related to TSB 24-2185, RDU vent hose letting contaminants into the rear diff. Probably not taking it to Detroit until that's been looked at.

Not hearing the sound for myself it is hard to gage... But one thing to consider is the brakes. I have seem multiple times where a shoe may start dragging when the wheels are turned. this happens after considerable wear.... at 63k it is highly possible that may well be the culprit.

Hello, I would like to take a look into your noise concerns further on my end. Could you please send us a message with your VIN and mileage?

The new style vent hose is apparently not available, so I had the dealer change out the rear drive oil which was described as "gross". They told me this would be an ongoing concern until they replaced the nonexistant part. Anyways, it was $170 for a vehicle 3,375 miles past warranty. Not particularly happy.

My wife's 21 Bronco Sport is experiencing the same issue. Sounds like turning my Ram Rebel while rear dif e-locker engaged (sort of like one wheel is having hop or slip a bit.
Has 140,000KM.
This noise started very shortly after it was in having the brakes serviced. I believe they resurfaced the rotors and installed new pads. The dealership also did some sort of a computer update.
Looking at changing the gear oil in the rear differential as I've read that this may help; but not holding my breath.

Just took mine in for the same issues. Turns out I need a new rear differential. Falls under power-train warranty.
