    Default 2001 2500 8.1 L - knocking felt under floor

    I have a 2001 2500 8.1L Suburban LT w/Autoride and am feeling a knocking at my feet primarily when decelerating at speeds beyond 45 MPH. You can hear it on a smooth road. Not sure what it is. Any ideas?

    Default

    Does it increase or decrease with speed? Just a tick or more of a hard knock?
