    I got a 2001 chevy silverado 1500 5.3lt and I just recently got my truck lifted and its making this weird noise when I go over 20mph it sounds like a grind and a rattle and I took it back to the place I got my lift put on and they said they have no idea what it is. If you know anything please share with me I have no idea

    Can you tell what area the noise is coming from? Front? Back? Middle? A "noise" is a pretty broad description and can make diagnosis pretty hard. Can you get video of the noise and post it?

    It sounds like it is coming from the left front driver side and yes I can try to get one today

    From what you've mentioned, I going to take a guess, and say that the Grinding/Rattle Noise, maybe coming from the Front Wheel Hub Bearings???.....its a common Problem on the 1999" to 2006" NBS Trucks.

    yea, get us a vid of it. That may help narrow it down, it could be anything at this point. U-joint, front diff, front wheel bearing, front CV axle, transfer case. I find it odd that the place that did the lift can not figure out what it is.

    I find it weird to but when I'm driving down the road with the windows up it sounds like it is coming from the wheel well but when yhe windows are down it sounds like its right below driver. And when I get off work ill shoot a video

    I know its after the fact, but When you went back to the Shop, that did the Work"the Lift"....did you take them on a drive, so that they could hear grinding/rattle Noise??

    Sounds like a t-case or ujoint noise to me. We can tell better when you post a vid

    Yea the shop told me to bring it back after 500 miles to make sure the bolts on the lift haven't come loose and they checked it and said they could not find out the nois

    if the noise is that evident and the shop can't figure it out then I would be questioning the ability of said shop. Was it a detail and accessory shop?

    It sounds a lot like the sound that @reggiecab2000 had on his truck. Here is his post and video. http://www.gmtruckclub.com/forum/showthread.php/112531-need-help-asap!?highlight=reggiecab2000

    Try listening to the video in the above link and see if it sounds like yours.
    It turned out to be his transmission.

    I have compared your vid and his multiple times. Thru my computer speakers they sound pretty close in sound. Yours seems slightly higher pitched.

    I don't know what it sounds like it 4wd. The truck didn't make this noise till I got the lift on I don't know if the drive shaft is not long enough or what

    I don't know if the trans because it doesent slip or anything like that

    His did not slip either. It was a damaged bearing inside causing the noise. Do they sound the same to you?
  18. GiddieUp

    GiddieUp New Member

    Somewhat but mine does not do it in reverse and his sounds like more of a clunking noise like sounds like something is hitting something else

    i had a needle bearing go bad, yet even with that noise you could hear on mine, my truck drove perfectly fine, but with that noise i did not want to risk damaging anything else.

    how big of a lift did you get and how many miles do you have?

    i would say to do what i did, lift up the rear wheels and spins them with a friend in the drivers seat and listen around for where its coming from
