Vibration after SYE + CV. What could it be?

Hello jeepers,
This is my first ever post ever considering i just joined a mnute ago. The reason i join is because of the vibration in my 2003 wrangler X. I installed a rough country 6 inch short arm kit, later i will be purchasing the long arm upgrade. I also installed the rugged ridge slip yoke eliminator and an adams custom driveshaft for a 6 inch lift. I dont know what to do next. The jeep only vibrates between 30-40 mph while accelerating. Below or above that the jeep is smooth. I just wanted some suggestions if possible what to do. I dont know if i want to install blocks to drop the transfer case or what. Thanks TheOrffs

It sounds like it needs to be checked again. Stuoffroad.com has a great write up.
