| My 2002 Sierra SLE with the 4.8L V8 has an engine noise that has been going on for a few years. Sounds like lifters to me. Was told by the dealership that it is normal and will not harm the engine. It only rattles for a moment when accelerating a little on the fast side. Does anyone have the same problem or know of a fix? Thanks | |

| I have an '07 Silverado Classic ext cab W/T. When the transmission shifts at 40-45 mph there is a brief vibration or shudder that can be felt in the steering wheel and gas pedal. When I took the truck in for it's first oil change I mentioned the problem to the dealer's greeter. When I picked the truck up I was told that the transmission was operating as designed. They did not road test the truck, just plugged it into a computer. Could this shudder be caused be the two piece drive shaft? | |
My 2003 silverado has a noise when applying the gas that sounds kinda like a spark knock but it is coming from around the catalytic converter area. I had two mechanics tell me it was a loose baffle in the catalytic conver so I took it to the dealer since the emissions stuff was still under warranty. They put a new catalytic converter on but it still makes the same noise. The mechanics at the dealership told me "that some of these trucks just make noises". They did not seem interested in looking any further for the noise and quite frankly I can't afford to pay their prices to "guess" what is wrong. I can climb under the truck and listen as someone puts on the gas and the sounds if coming from somewhere around the catalytic converter area. Any ideas?
