[ROCKO]

I bvelieve it goes away it could be masked though by the sound but then its not there when at a slow coast or when sitting at a idle. Could it be the valves or something like that?
 It is lifted and I am not sure if its tthe stock drivelines or not cause i bought it with the lift. I just added 1" longer shackels but if it was the driveline wouldnt it shake the truck when at higher speeds?

start with a new drive line...that most likly your problem
