| I have a noise coming from the drive shaft area. Thought it was a disc brake squealer, turned out I was able to eliminate those. Sounds like it may be coming from the drive shaft center support bearing. Does this seem to you, that this may be where the problem is? If so what are my repair options? | |

I noticed this about a week ago when I stopped at a gas station in the middle of the night to buy a pack of smokes. As I returned to my already running truck I noticed a humming/buzzing sound coming from right behind the driver side , where the cab meets the bed of my truck. To give a better idea of what kind of noise it was making imagine a leaf blower from a hundred yards away. I drive my truck for a living and have 180,000+ miles on it already. Does anyone have an idea of what this sound could be? Thx in advanced for any help.

Thanks for the help I apologize for starting a new thread , I wasn't sure where to post... my buddy suggested it was the fuel pump as well but I wanted to get some confirmation from a third party before getting it fixed... |

| My 98 Z71 had the same noise. Lasted for quite awhile before fuel pump stopped working. A trick to get u through is if the pump does quit working... Tap the tank with a rubber mallet, or shake the truck (with at least half a tank of fuel) and most times the pump will work again for a while. | |
| i also have a 03 silverado 1500HD and i also had this exact buzzing sound but it wasnt at idle speed but right around 120km, i had a friend sit in back so he cuold find it and it turned out to be the plastic plug just behind the driver side back seat, i pulled it out and threw it in the glove box and havent heard it buzz since, hope its as easy as that for ya | |

I have a squeak that just developed tonight. It seems that the squeak is audible once for each time the driveline makes a revolution. Could it be a u-joint? There doesn't seem to be much play in the driveline when I'm under it and try to move it around. There seems to be a bit of grease on the transfer case housing coming from where the rear driveline enters the transfer case but that may be normal...the grease isn't fresh or dripping by any means. Anyone experienced the same thing? Thanks in advance.
