Noise at 30mph - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Around 30mph there is a whining noise in my 65 C10. It sounds a lot like the big oversized off-road tires running on the highway. It only starts at 30 mph and stops when I let off the gas. I thought maybe the rear end need more oil, so I brought it to a lube shop to have the oil changed in the engine & rear end. The rear end was bone dry. Well, it now has oil but the noise is still there. It’s weird because it is only noticeable when I press the accelerator. Any thoughts?
