I just purchased this truck about a month ago, and presently am experiencing a drive train vibration when it hits 60 to 80kph (sorry for the lack of Canadian mph). It will do it (shudder/vibrate) no matter what gear it is in. The net points in 2 different directions when it comes this chassis assembly, one is a bad ujoint and the other is suspension dampener. Was wondering if anyone experienced this type of trouble and could shed some light on it - thanx in advance.
