fast4popper Posted November 9, 2004 Report Share Posted November 9, 2004 I am wondering what the loud thud is as I sit idle in my driveway? does anyone know? I am thinking it is the fan clutch or something of that nature? It almost sounds like someone around me is slamming a car door. am I the only one that hears this or are there others out there that hear the same things? thanks for the help -C- Link to comment Share on other sites More sharing options...

black03zr5 Posted November 9, 2004 Report Share Posted November 9, 2004 I have the same thing. It is like the ac compressor clutch is engaging. However, it still happens even when the AC is off. When I take my truck in, that will be on the list. Speaking of which does anybody ever get a loud metal clank while they are driving at lower speeds. It is high pitched and sounds like to pieces of metal hitting. The dealer has looked at it, and can't find where it is. Link to comment Share on other sites More sharing options...
cadowns Posted November 9, 2004 Report Share Posted November 9, 2004 Could it be the thermal expansion and contraction of the Muffler? Many of us had this noise before we trashed the stock muffler. CD Link to comment Share on other sites More sharing options...
black03zr5 Posted November 9, 2004 Report Share Posted November 9, 2004 I don't think so. It doesn't happen when the truck is sitting, only when it is moving. I can't really describe the sound other than a ching noise. Could it be the thermal expansion and contraction of the Muffler? Many of us had this noise before we trashed the stock muffler.

DaGeorge Posted November 9, 2004 Report Share Posted November 9, 2004 does it happen at low speeds when you give it only a little pedal?? I have that. It feels kinda like driveline slop. but it only does it if it hasn't come up to temp. My blazer would do the same thing in 4wd and cold. Link to comment Share on other sites More sharing options...
SPEEDCRAVIN Posted November 9, 2004 Report Share Posted November 9, 2004 Man there is so many things that a loud car door closing thud could be. If you are near a wall or even in the garage the noise more that likely be amplified louder. this could be anything from your A/C compressor engauging, or posibly it could be a mode door sticking a little in the dash and when it closes making the noise... Give us some more info on your noise... JOSH Link to comment Share on other sites More sharing options...
