Hi, I have a 1993 gmc suburban k1500 on 24" rims and I recently replaced the tires on it. After about a week driving on them I started get this howling sound when driving 30mph or higher, and when coming to a stop I get a whining down sound. I have had both front and rear differential serviced with gear oil. But I can not figure out where this howling sound is coming from, can be heard very clear with windows up but not clear with windows down. I can be heard from drivers seat and sounds like its coming from front. But also can be heard from rear and sounds like its coming from rear. What possibly can this be?
