I am getting vibrations from the angle on my rear driveshaft in my 2005 rubi. I've already installed a transfer case drop, still have to tweek my pinion angle to see if that helps. My question is, I know when you install a SYE on a 231J that you can use the front shaft from a Cherokee to get a cv in the rear of a yj and probably tj. Is there a cv from another vehicle that will work in the rear of a rubicon? just am having a hard time justifying dropping $400 on a driveshaft so I thought I'd try this first.
