Jiggle in rear end

Hey guys I posted last week about a jiggle in the rear end of my truck only at take off. Gotten many comments about it possibly being u joints or carrier bearing. I also notice vibration at higher speeds through floor board/gas pedal. Could that be another symptom of driveshaft stuff? TIA

 

Vibrations are a tricky/impossible thing for us to solve over the internet. Very subjective in nature. To answer simply, yes all those symptoms could be driveline related but none of us can say for sure. Here's a huge thread with more info than you ever wanted about helping solve some of those problems:

You should get together with this guy.

pull drives shaft, its only 10 bolts
then check joints for binding and center bearing for smoothness and if rubber is shot sunk down in bracket
