94YJ Vibration when accelerating
I have a 94 YJ with around 120k miles. Engine is in great running shape, the transmission shifts fine, the clutch seems to engage, disengage and all around function great. But, when i get to around 45 mph and up, there is a vibration somewhere in the drivetrain. When I let off the gas and coast, it goes away. Could this be a driveshaft, u-joint, or tranny problem? It just started a while back and I returned from out of town and drove it, it seemed like it had gotten a little more severe. Anyone have any ideas??
