    On a prostar picked up a new trailer and noticed the drivers side leveling bag was low and the mudflap was dragging the ground. Headed down the rd to a track stop and just started chattering in 8 high sounds like the trans maybe rear end.. could these two be connected.. the low bag and the chatter?

    Yes.
    If your ride height is off the driveline angles will go with it. Extra pressure on the rears and tranny, can make shifting feel sticky.
    Can cause vibrations... bad news .
    Usually an easy fix though.
