My 1990 V10 with 700R4 developed a noise not unlike a bad u-joint. It seem like the front u-joint on the rear driveshaft. I replaced both u-joints. The noise is still there intermittent as before. It seems to be coming from mid-truck area more to the passenger side. It happens on dead stop on medium to quick take off. The truck is stock and runs fine otherwise. There is no vibration at any speed. It happens in Drive and Reverse. Any suggestions ? Thanks Charlie
