Driveline noise/vibration

[Tanker93]

You said it all started after the carrier bearing was changed, I wonder if the shop that did the work didnt mark the driveshafts and put it back together 'out of phase'. These shafts are balanced together which means they can only go back together 1 way or you will have vibration/pulsation issues. Might pay to take the whole shaft assembly (Gearbox-front diff) off and give it to a drive line shop for them to balance. They couldve even put it back together the right way but accidentally knocked one of the weights off
