noise from the rear
I have a similar issue currently with worn out Yokohama S drive tires. Will be buying Michelin next time.
I'd expect it to be something in the rear before a wheel bearing though. They go straight to more of a grinding noise (at least when I've had them go bad on vehicles).
FWIW, my Durango started making a whining noise that I thought was just the tires. I was wrong and it is loud now and the rear needs to be rebuilt. It's been whining for at least 5,000 miles.
Would help to know mileage.
Had you inspected the rear rims for any bends or dents, inside and out? Did you watch the tire guy at the balance machine to check for any unusual weights?
What speed(s) does the noise occur at?
Does the noise happen when accelerating slightly, decelerating slighlty, and/or in neutral coasting? This loads the driveline and can narrow down suspect components.

The noise is continuous and on get slightly quieter when off throttle. The old girl has 250k miles on her but she is still a race horse. She just needs a little TLC.

anyways, I'd start with a diff fluid change and possibly the center driveshaft support bearing if it hasn't ever been replaced.

To add from my recent personal experience of the rear end noise and my rear wheel bearing going bad on my E55 in February, the sound my car made was more of a squeal with a slight grind, speed sensitive noise which got progressively worse until above 60 MPH. Then the noise went away ENTIRELY for about a month. Then the noise came back and was immediately worse and then poof, grinding halt, boom, pow, surprise. Dead on the side of the road with wheel almost completely falling off. New Rear end. (bearings, hubs,speed sensor, rotor, pads, axle) $$$$$$$$

Previously, when I had put the car up on jackstands to listen for the noise while troubleshooting, it did not make any noise because the wheels were not under the load of the car weight. If you don't have access to chassis ears to pinpoint the sound, take it to a shop which does. I could've saved a few thousand dollars in repair if I had pinpointed my RR bearing sooner with chassis ears.
With your high mileage, there is some other sound advice as to changing diff fluid and such.
A good way to check for bearings is lift the car on the frame, and grab the wheel- lift up and down and left to right and in and out. Should be no give, no pop or clunk.
A decent indy shop can spot suspension problems easily. In my case they found worn out front ball joints which I changed first, but turned out not be the problem.
If bearings are suspected, and you want to nail it, get a set of chassis microphones (ears).. Can be had on eBay or Amazon for under $200 for the wireless ones which are considered substantially better. A shop may have a set to use as well.
That being said, 250K is a lot of miles. I suppose bearings start to give at some point.
