    Front end growling noise after brand new diff but only under decel???

    Ok here goes. I had a what I thought was the notorious front end growl, but only
    Under decel, it starts getting noticeable above 40mph and is very annoying by 60mph. Seemed like the transfer case may have been making some noise as well. I bought brand new rebuilds from a very reputable company, I put both units in today
    and
    Couldn't wait to go for a ride and hear a nice quiet caddy....... Noise was still there! I am at a complete loss and at my wits end! So to reiterate, the noise is only on
    Decel. If I push the throttle pedal slightly is goes away. Noise is there whether the
    Truck is coasting in neutral or in drive, with or without traction control or with the
    Towing on or off. The only way it goes away is to slightly push the throttle whil still slowing down. As if I'm removing the "negative load" it sounds like a rotational
    Noise kind of like a drive shaft is rubbing on something, but I have been all over
    This truck and I can't find anything that is making any contact.
    Thanks for any help

    the noise is not a whine. its pretty loud, almost what a drive shaft would sound like if it was making contact with somthing. it really sounded like a bad front end, but i guess i ruled that out.

    Axle half shafts maybe? Rear end, mistaken for a noise from the front?
