Drive train vibration

[Craig Wood]

My 2002 Expedition has developed what appears to be a drive train vibration. The vibration starts at 40kph and continues all the way to at least 120mpkh. Both rear u-jojints were changed with no improvement. Going to change the two u-joints on the front drive shaft . Going to the tire shop tohave all the tire checked for broken belts and rebalancing. We did notice a small shiny spot near the middle of the rear dirive shaft when it was removed (1inch by 0.5 inches). Shaft may hav lost a weigjht, any body have these weights on trhier exy. Anybody have any ideas?

Try posting this in the Power and Drivetrain section. I don't know if anybody even looks in this section.

More than likely its the clutch pack and the ring and pinion making the noise. I have a 2003 Expedition and I've learned that a lot of f150's, explorers and expedition's have this problem. Look under the TBS code 05-23-3
