hey guys, lately my truck has started making a howling noise when I drive it. it only happens at about 10-30 mph, in both 2wd and 4wd. its not that loud, maybe as loud as the tranny and transmission's gear noise. I know its from the frontend because I can feel it through the steering wheel (it vibrates in tune with the noise). it only makes the noise when moving, and makes it when the truck is in gear or in neutral. 350/SM465/Rockwell/d44 closed knuckle drum brakes.
any ideas?
thanks
