In the Ft Axle, there's a double U-Joint (called the Cardan Joint) that has this, spring-loaded, Ball & Socket that will squeak. You'll have to pull the DriveShaft to check it though (It'll squeak in you hand sometimes....)

Next, try locking your hubs in manually (if your 4WD) and see if that eliminates the vibration as a test for bad needle brgs.
