noob cv joint issues

So the noob that I am, i put a 3 inch lift on my 04(billy 5100's, eibach coils, and toytec aal). After i installed it I had some vibrations up front, which I assumed was the cv joints. The vibrations have gotten a little worse considering ive been driving around like this for about 2 months. I just ordered a 1 inch diff drop kit in hopes that it will fix the issue. Just wondering if anyone else has had these issues and if they know for a fact that it is the cv joints or not. If anyone knows any other remedies please let me know.
