02 Sierra extcab driveline issues PLEASE LOOK AND COMMENT!!!!

Lowered 02 extcab sierra with driveline vibrations... Please look and comment!!

So I've got a 02 sierra extcab lowered 3/5 and it has a vibration between 5-20mph it has a new carrier bearing and a 4* shim for pinion angle, also has the 2 piece driveshaft. Anyways the center support bearing hangs down lower then rest of the driveline, I was told I needed to raise the support bearing to correct the angle and that would cure my vibration issues OR should I try a bigger shim in the rear like a 6*???? Here is a pic kinda hard to see but you can see clearly how it hangs lower any input would be greatly appreciated!!

^This. On ecsb trucks you need to raise the carrier bearing to avoid having those vibrations.
 
01droppedsilvy - I merged your threads, in the future please avoid posting the same thread in multiple subforums.

as 2005_Silverado said the carrier bearing is typically raised, what is your pinion angle? If youre not sure a checker can be purchased fairly cheaply.
