My 2005 Sierra has a howling sound when I reduce my speed. It starts around 50mph down to 40mph.

check your axle fluid first, then check your wheel bearings. if you can find an area to drive in a circle drive to teh left and if the noise is on the right side it may be a wheel bearing on that side. then drive right and vice versa
