Ok I have a 1995 explorer 4wd with the 6 cylinder 4 door. I have noticed a vibration coming from the rear end. I changed both front and rear U joints. The crank case is full of fluid. Anyone know what might be causing the vibration?

 

Can you describe the vibration in more detail? Is it only when accelerating, only when coasting, only above a certain speed, only when turning left, only when you have a passenger in the second row, etc.?

The vibration is usually when accelerating at 50 to 54 mph..
