Why is there a loud howling from the right rear of my 2002 2500HD 4x4. on 2002 Chevrolet Silverado 2500 HD

I is worse when it is hot outside and when I ride the brake it stops. Also the rear rim is substantially hotter than the rest when I get out to check them.

could be a wheel bearing noise. better get it checked before the issued becomes much worse and more damage is done.
