Carrier bearing drop just creates other issues

first time poster, long time stalker...I have a 2016 tundra super crew with 2 inch lift in the front and 1" blocks in the rear...I did have a 2" in rear but changed it. I have tried every size drop and I am convinced you can never get rid of the driveline vibration. the more you drop it, the more vibration I get at 60-65mph. the less you drop it you get the vibration at takeoff. with 1/2" drop I get it at take off and 60-65. with 3/4 you eliminate it at take off but more pronounced and the higher speed. the less you drop the better at high speed but bad at take off. how can anyone not be bothered with the issue?

 

I just got done lifting the rear of mine with camburg inch and half shackles and king shocks on 37s no vibration at all in mine not sure why you would be having it

 

is the shackles any different than blocks as far as drop kit?

 

Not sure I didnt use the carrier bearing drop kit tho what I ment to say earlier
