Okay so I own a 2008 chevy silverado 1500 LT with a 5.3 flex fuel. I started hearing a strange whine noise when im driving. If im in drive i can hold the brake and hit the gas and itll make the noise or while im driving its a continuous whine that goes up or down in tone during acceleration. When it is in park however, the whine is non existant! Ive had a few of my mechanics put me up on the lift to scope it and they say its the loudest at the torque converter. We dropped the tranny pan and did the filter and gasket and flushed it. There wasnt really anything in the except the normal crap. My transmission shifts beautifully and the tranny service has always been done on it. So now I am at a loss for what it could be. When I bought it I was told it had a one inch leveling kit on the front and ive looked around and found that sometimes it can make the oem cv axles and wheel bearings fail but it wasnt gradual it was all of a sudden. And i didnt start hearing the noise until i realized that my left cv axle and wheel bearing had failed so i had both front cv axles and wheel bearings done. It still makes the noise. I have been told by others that it could be one of the differentials or the transfer case but I am at a loss for what it could be! HELP!! I am so confused and worried my truck is going to give up on me! I cant afford the engine or transmission going out ...©
