Post Lift Vibration

So I did the Bilstein 5100 lift and love it, however, I am getting a vibration from the front that is baffling me. I got the wheels aligned, I tried with the differential drop kit and without, with the carrier bearing drop kit and without, and every combination. The wheels are balanced.

***Here is the latest discovery to my dilemma, the vibration completely disappears when I engage 4x4. When I go back to 2 wheel drive, it immediately returns. The worst of it is at around 35MPH.

In more scientific terms, it is NOT a steady beat like buzz, buzz, buzz, buzz, buzz. It is more like buzz buzz buuuuuuzzzzzzzzz, buzz buzz buuuuuuzzzzzzz, and so on.

Thank you!

 

Sounds like you may need to install the clamshell bushing from ECGS.
