So, I have a 2011 Jk 2dr with 4.5" RK lift. I replaced the front driveshaft with an Oliver's double cardan driveshaft and had no issues. So I then decided to replace the rear with the same style driveshaft and now I have a vibration under throttle. When I let off it goes away. Did I mess something up in the pinion gear preload when I installed the new yoke or is this normal with double cardan setups? Thanks in advance
