I have a 98 Silverado 4x4 with a lot of miles on it. I notice that under acceleration the rear end starts whining around 35mph and continues from there. It does lessen a little bit at higher highway speeds. If you let off of the gas and just coast the sound goes away until you hit the gas and it start whining again. A friend told me it may be the pinion bearing but I wanted some other opinions. Anyone have any other ideas? Is there anything I can check before I start just replacing parts? Thanks
