My Ford V-10 power train is whining between 61-63 mph. It sounds like a bearing or tranny issue rather than engine whine. 43000 miles. After 63 it goes away. Anyone else? Solutions?
It might be that your carrier bearing's are going out, or a universal joint is worn and throwing the drive line out a bit. If you find one worn item, I would just go ahead and replace both carrier bearings(if their are two) along with the universal joints. When ones gone south, the others soon follow. Check the rear carrier bearing first. Get under and give them all a good shake and see what you can tell. Also check that the engine mounts and transmission mounts are sound.
