Has anyone out there replaced a 3.73 differential with a 4.10, specifically in a F-250? If so, did you replace the entire housing, springs, etc? I don't know if the 4.10 guts would bolt into the 3.73 housing or if it'd cost more that way. Does the rear half of the U-joint mate up with the drive shaft?

Thanks again,
-Bob
