I went from a 3"ish lift to a 4" lift and now I'm experiencing some vibrations under throttle. Decided to switch to a Double Cardon shaft so i adjusted my pinion to point right at the transfer case by making my own castor correction plates and using an angle finder checked the angle difference from the pinion to the shaft, its ~1°. Im still experiencing some vibrations though, they definitely go away if i remove the front shaft although there is a very minor vibe from the back (which i also adjusted: the pinion flange and transfer case flange are in parallel). My question is, does anyone else have this problem? How bad is a slight vibration if i leave it? I don't really want to do all the work again for .5° adjustment only to find out that it makes no difference... I can live with the vibration as long as my driveshaft isn't going to explode in 6months. Im pretty picky too so its probably not as noticeable to someone else.
