Driveline vibe or axle wrap after 4" lift?

[Captain Starbucks]

After I did my 4 inch lift a few years ago (blocks in the back) I had a little bit of a vibration ONLY in first gear at takeoff. I figured it was because I did not drop the carrier bearing (two piece driveline).

I recently bought a carrier bearing drop kit but it specifically says on the last line of the directions that it will not cure 1st gear vibration and that it's axle wrap.

My question to you is: So should I return the carrier bearing drop kit since I don't get a vibration at any other speed?

And how do I fix axle wrap?

Thanks.
