    I posted this on a Silverado forum and haven't had much luck, I was wondering what you guys thought.

    I have this rattle coming from what sounds like the rear driver's side of my truck. It sounds exactly like a card in a bicycle spoke. The noise only happens after the truck has set for 2 hours or more and it'll last for about 5-10 minutes. I will quit at 30 mph and come back anytime below that. I live on a gravel road and it will stop as soon as I hit the pavement, and when I leave work, which is on pavement it will do it consistently for around 10 minutes. I have walked along side the truck and it sounds like it is coming from the driver's side rear wheel area but I am not sure.

    The noise is loud and you can hear it with the windows down and it echos off buildings. It has been driving me crazy trying to fix it .

    So far I have :
    completely replaced the rear end with a new unit with new axles.
    replaced both CV axles
    replaced all brake pads
    replaced the rear driver's side brake caliper.
    lubricated every contact point.

    What could be causing this noise? I am hoping it is not the Sun Gears in the transmission. I would appreciate any input.

    I have a 2004 Silverado with 200k miles with the g80 rear end 17" factory wheels and tire sizes.

    That may be it. any idea on how to tighten it up? If I remember right it just snaps in there.

    To make a long story short I no longer have a spare tire or spare holder..

    There is no zip ties on my drive shaft.

    The dust covers on the rear brakes rust out real bad on disk brake rear ends, but I suppose you may have already been through those.

    Leaf spring clamp. The clampy thingy that typically holds the 2nd leaf to the main leaf. Usually there are 2 on each leaf spring. The clamp will spread and get loose esp if you brake hard a lot. It can be tightened/ bent back into shape with big pliers

    Aluminum or alloy wheels? Check for very small fine crack/cracks. Check lug nuts for correct torque. Check lug holes for wear. Check tire/tires for a flap or cut in the tread face. Seperating belts or seams in the tire. All of these things can cause a noise similar to what you discribe. Just some thoughts.

    Maybe you have a Wombat stuck to your tire and flopping against the fender and road as you drive.
