Viberation or drone from about 45-65 mph

    My truck is an 05 silverado. 4x4, ext cab has about 83k on it and when im driving from around 45-65 mph there is a viberation that i can hear and feel on the floorboard. It kind of sounds like when you hit the rumble strips but no that extreme, and it goes in and out the faster you go the more it does it. i thought it was a wheel bearing so i replaced that and it still does it. i did a search and some people were saying maybe the driveshaft? but doesnt seem right with the miles and only ever pulled my motorcycle. the noise is hard to explain but its starting to be a pita! any help or input id appreciate!. thanks

    Any chance you've recently made exhaust modifications? If you have, its possible you've got a resonance problem. Other than that, I'd rotate the tires, and see if it's a tread issue. Worn tires can do the same thing.

    I recommend taking it to a tire shop and having them evaluate the suspension. They'll do this for free, usually (like at Les Schwab) and you can deduce whether or not there's something in the suspension that's causing the problem. I suspect something is out of alignment or spec.

    Can you post a video of the sound?

    There can be any number of things.... can you feel it in the wheel? what does it do when applying breaks firmly? Is the rim hot to the touch? what happens when you throw it in neutral when it is happening? Maybe a warped rotor, sticky caliper, bad tranny mount or even a hub that has not fully disengaged.

    Do you have an Auto AWD position on your transfer case?
    If you do, are you driving in that selection?

    Sounds like a seizing ujoint to me...the sealed for life units will dry out and seize, and still show externally that they are good. Pull the shaft, and flex the u-joints by hand and see if there is a tight one.

    Thanks for the help so far guys, i tried to get a video but you couldnt hear it on my phone. it still does it when i put it in neutral, and when i apply the brakes. and noticed that it is a lot more noticeable if its colder out? could it be the oil in the front diff? and i the viberation is mostly on my drivers side floor board dont really feel it in the wheel! im almost out of ideas but i think ill try the u joint since its a pretty cheap fix and go from there. Thanks again for the help

    I think your onto something with the universal joints... I've personally not had them cause a vibration when they have failed... but I do not see why the couldn't. Anyway, they are cheap and easy to replace and sounds Luke a logical place to start.
