wow,,,, the sole purpose i got online tonight is because of this EXACT same issue i had for a couple thousand miles and last week my driveline let go, and exited the vehicle....(had to go retrieve it in a field next to highway)... pic to follow soon.
for last three days i have been looking into this issue. ford is not willing to warranty for obvious reasons(carrier bearing shim and lift kit, 4"front/2"rear) however they did provide me with a TSB that says they know of a shudder/vibration issue and sent out a fix for it. what you may not feel stock is magnified with the lift angles on the driveline.
talking to a one of the best shops in Montana i was told that a one piece shaft from steel will have too much 'jump rope' effect, and the only possiblity to get away with a one piece would be an aluminum shaft ($$$)....
the TSB (TSB09-20-5) states that the driveline should have a 3 degree optimal operating angle,,,,,
ANY TECHS PLEASE CHIME IN
Again pics to follow soon
