Clunking at low speeds, differential, wheel bearings?

[Lampcont44]

Hey guys I've been trying to narrow down this noise I began hearing a week ago. I first noticed a tumbling/clunking sound when I am slowly approaching to a stop and then slowly accelerating. I dont notice anything at regular speeds. I can also hear it more when im coasting at slow speeds (it's more obvious then).

I took it to a dealer to no avail (could not replicate sound ).

I decided to jack it up and hear it for myself. Here's a video of the sounds as im turning one of the wheels. I cant tell if its coming from the differential or the wheel bearing(s).

What do you guys think?

2020 Ranger FX2 with a 2.5 inch front level (Bilstein 5100) and 66K miles.

There is a TSB for driveshaft and ring pinion gears. Had both replaced under Ford ESP earlier this year. Got a shudder when decelerating and starting. Clunking when stopping and starting.

I’d search for driveshaft threads.

My ‘21 tremor makes the same noise when jacked up, yet it sounds fine when driving it.
I did have the rear driveshaft hanger bearing replaced because it was noisy. I originally thought it was a bad wheel bearing, but it ended up being the hanger bearing. So maybe that’s something to look at.
You could check your rear diff fluid level to make sure it’s correct.
(I learned that the rear diff fluid lubricants the wheel bearings, so the correct level is important)
