I am thinking about putting on a CV joint on my driveshaft. The reason for this is I am getting a vibration under acceleration. I do not have any lift, however the angle from my transfer case is quite severe as compared to the pinion side. I lowered my trasfer case by moving the spacers, that are below the transfer case crossmember, to between the crossmember and the frame. This got rid of the vibration but when I put it in reverse it feels like it is binding and there is a very strange noise coming from somewhere. Has anyone used a CV joint on a slip yoke? I can get this done with the new CV joint and having the shaft shortened and balanced for around $175. Is this worth it?
