How about jack up that wheel and turn it by hand ..
and also wiggle it, left-right, up-down.
something might be apparent.
You have to have a wheel cock or two to do this ..
since you'll have a rear wheel off the ground..
and since brake on or in-gear is not an option..
need to chock the wheels so it won't roll off the jack.
that's what I'd do for a simple first step.
lol...
when I used to fix cars full time..
people would call up and want to tell a long story about when it did
what etc..
I would just tell them ..
tell me the basic concern or symptom..
then get me the car !
Nothing is going to change until someone really examines the thing
properly.
No amount of talking about it will change whatever is going on in the
wheel, car or van.
Let us know what you find out.
Does applying the parking brake while rolling have any affect..
like increase or decrease the noise ?
