2015 Traverse, get wobbling noise coming from rear tire area at highway speeds. Sound increases when brakes applied. Noise starts after 10-15 miles and continues for approx 5 miles then stops. Cause?

Wheel bearing is the most likely cause. Prob a 1.5-2 hour labor rate job in the shop.

CHECK YOUR UNIVERSAILS COULD BE WORN OR DRY U NEED TO PULL OUT THE SHAFT TO CHECK PROPLEY CHECK FOR STIFFNESS AND NOTCHEY MOVEMENT

SOURCE: Howling in the rear end.

I have a front wheel drive and at 120k I had noise in the back. It turned out to be a bad wheel bearing. It was tough to diagnosis because the quick check is to see if the wheel wobbles when pulled, but mine didn't. It wasn't untl they put it on a lift and found the wheel wouldn't roll freely.

That's a hub bearing. Replace the one that's doing it. I'm assuming this 'roar' is coming from the front, NOT the rear.

The high pitch sound may come from the brake pads as metal parts hit the disc to signal the owner that it needs change. The metal parts gets exposed when the pads have worn out. The brake also has a hub to cover the disc. See if the metal plate is hitting it but this issue would appear when the wheels are in motion. Check if it is the belts, have the tension checked out. Other than that the bearings are the other items on your wheel that could cause a high pitched sound when you car is in motion.
