    Hey, my friend has a 1994 Chevy Silverado Z71 w/ 350. He noticed that whenever he goes 50mph to about 60mph, it makes this really wierd, loud, low, almost a moaning sound. My dad and I thought it could be the U joint, but the guys at the dealer said that it sounded like the pinion, and it would cost $1000 to fix. does anyone know anything about this, if the dealer is ripping him off, or anything? Thanks, -pete /forums/images/graemlins/k5.gif /forums/images/graemlins/truck.gif /forums/images/graemlins/usaflag.gif

    Friends got some problems in his truck this vintage, he says it's carrier bearings, but not sure how he "knows" this.

    Thanks guys, I told my friend to try accelerating, the sound goes away when you let off the gas. He asked the guy he bought it from if it could be the pinion or carrier bearings. They sent him to this guy who is supposedly rochester's "rear end specialist" (lol, not like that), and he is going to check the bearings. Thanks for the help and suggestions, I had no idea what was going on, thanks again /forums/images/graemlins/thumb.gif
