I have a 03 cc dually 2wd with 15000 miles.Under hard acceleration I feel a bad vibration,which feels like when your pinion angle is off.It don't seem to be speed related,only when I get on it hard.Truck runs smooth as glass at a 100 mph,so I know it's not a balance problem.Feels fine when driven normal.Has anybody experienced this with there truck.

Saw this last night in the TSB folder. Not sure it is the problem but is a place to start.
