I have a 2003 Land Rover D2...just recently, a vibration started coming from the rear. When I'm driving straight, it's vibrating at any speed. When I'm turning, it feels like a shudder. It is coming from the rear. I have checked the most common issues that could be causing it. The flex coupler is a little dry rotted as the U-joint is a little worn. I am about to pull the rear diff out to go through it but was hoping that someone might have had the same issue and could tell me any possibilities that it could be before I did that! Has anyone else had or is having the same issues?!? I am open to diagnostic help!
