Cupped tires can make noise rotate them to the front to see if the problem goes with the tires they do have wheel bearings that go bad and the rear diff but the rear diff will change noise when your on and off the gas

SOURCE: '03 Merc Mountaineer humming noise when turning

If same tires as before & air pressure set correctly, or as usual, a humming when swerving, or turning one way or the other or both, it's usually a pretty good indicator.

SOURCE: 2002 Mountaineer SUV, 4WD, Especially while turning the wheels

I had the same problem with my 2002 Mountaineer at about forty thousand miles. Murcury replaced the steering column free under warranty. I now have ninty two thousand miles and it's back. The rear end is making a whining noise, the tranny is starting to slip, and the rear window regulator went out. Why did we buy a Mercury?????? Disgusted Dave!!!

sounds like you wheel bearings need to be greased up. Good ideal to have full grease job anyways. U-joints, tie rods, and bearing especially

Loud humming noise coming from the rear/tires? of 07 pt cruiser?

Rub your hand over the tread and try and feel for cupping or uneven tread patterns. This will create alot of road noise. If not, have your wheel bearings checked.

I have a saturn Vue 2003 with 150,000 miles. there is a loud humming noise when driving coming from the rear of the vehicle. I have rotated tires and balanced. Tires have 65% more wear to go. Muffler...

Based on your description: 150K+left rear slowed down much quicker than the right +/ and the humming noise, there is a great possibility that the Wheel Bearings will have to be replaced.

Loud Noise & Vibration

Who knows without inspecting it, but check the tires. Tires can cause serious problems even if they look ok. Though tires look fine, they can have an almost invisible way of vibrating a vehicle also un balanced tires can cause vibrations

My front end makes a loud humming noise. At low speeds, I hear a humming noise and at high-speeds I can hear a noise in my tires. Not sure if it is an the wheel bearings, bad tires, or alignement.

Alignment will not create a sound by it's self. The most common cause of humming (especially if you have an agressive tread design)is a wear pattern in the tires...check for that or rotate the tires around & see if the noise changes. If it does then you know it's in the tires. & Not always, but most of the time a bearing noise will increase or decrease in intensity if you load up one side at a time by doing 35-50 mph & turning slightly to each side.

Humming noise in front end/engine fo 2001 Cadillac STS

Keep an eye on your temperature gauge until we figure this out, just in case & see if it climbs much/any at highway speeds.
