2011 DBCB Vibration on acceleration

I have a 2011 Tacoma DBCB TRD Sport with the infamous vibration on acceleration. Mine just started recently and starts around 10-15 mph and smooths out around 25-30 mph. I have searched and read many threads regarding the carrier bearing, u joints, leaf sprints, needle bearing. I thought maybe it was the needle bearing because I did just install 5100's earlier last year. I have them at the .85 setting in the front and I added the driver side lean spacer. A lot of people said that it doesn't happen to them in 4wd when it is the needle spacer. I tried that and I still have the vibration. I have no grinding, groaning, or squeeling. Only the vibration, but after 25-30 mph it has none whatsoever. I'm just trying to figure out a place to start, as I just don't want to start replacing parts and it make no difference. Any good place to start? Thanks!

 

You lifted the front, did you lift the rear too?

 

No...just the front as I was trying to level it out
