Horrible vibration from drivetrain.

[freeride707]

ive been having this vibration issue this whole week, started out only when its cold now does it all the time. anyway today i blew out a Ujoint. so i figured that was the issue. Well its not, i fixed it and still has the vibration. it feels like its coming from the trans driveshaft or rearend. Only under acceleration, gets really bad when the TC is locked up or in reverse. It shutters between gears then the vibration gets so bad the whole truck shakes and sounds like a the driveshaft is hitting the floor board or something. ive checked all other u jounts trans moutn etc etc.

help i need this fixed ASAP its my only vehicle and i cant be blowin out Ujoints everyday.

is this a weak trans pump causing this? or something else
i will be calling Brian at BTS in the morning

only codes ive got are a P1280 P1211 and a P0741, two ICP codes and a TC code, i replaced the ICP sensor and that didnt help anything. im completely lost on what the issue could be

Kind of sounds like the carrier bearing, but I could be wrong.

theres no slack in it and its bolted down tight...
