Vibration after lift?

[Obsledpuller]

Hello guys I just put a Sky RSK SD conversion kit on the front of my truck and I also put 4" blocks in the rear. The truck sits level and looks ok the problem is now I have a vibration wheni first start moving. I don't know much about pinion angle but maybe I need to fab up a dropdown bracket for the carrier bearing? Need a little assistance thanks.

Pretty positive ur driveline is out of angle. Need to shim ur carrier bearing.

A 5/8 shim under the carrier bearing resolved my issue with the vibration on take off.

Thanks added a 2"x1" box tube steel and the vibration seems to have gone away.
