I just replaced my rear drive shaft U-joints and they are now smooth are move easily. The splines were marked and reinstalled in their original orientation. The U-joints are in phase. But now I have a bad vibration.
I should add that I also removed the front drive shaft and greased both the U-joints and the splines. The U-joints were perfectly smooth and tight so I just reinstalled it - in phase - as it was originally.
So, I'm head scratching about the source of the vibration. Question: Does it matter if the front and rear drive shafts are "in phase" together?
